Replacement verdict
Not a drop-in replacement
The TLC2262CDR and TLC2274MDRG4 are not drop-in replacements for each other. The TLC2262CDR is a dual operational amplifier in an SOIC-8 package, while the TLC2274MDRG4 is a quad operational amplifier in an SOIC-14 package. The differences in channel count, package footprint, pin configuration, and supply current make direct substitution impractical without circuit redesign.

Key electrical and mechanical differences between the two devices
| Parameter | TLC2262CDR | TLC2274MDRG4 | Why it matters |
|---|---|---|---|
| Number of Channels | 2 | 4 | Channel count determines how many independent signal paths can be processed; a 2-channel device cannot directly replace a 4-channel device in multi-channel circuits. |
| Package / Case | SOIC-8 | SOIC-14 | Different package footprints and pin counts prevent direct drop-in replacement on the same PCB layout. |
| Supply Voltage Range | 4.4 V to 16 V | 4.4 V to 16 V | Matching supply ranges ensure both parts operate correctly in the same power environment. |
| Input Offset Voltage (Max) | 950 µV | 950 µV | Offset voltage affects DC accuracy; identical values indicate comparable precision in signal conditioning applications. |
| Gain Bandwidth Product | 0.71 MHz | 2.2 MHz | GBW determines the maximum frequency at which the op-amp can provide useful gain; a lower GBW part may not meet bandwidth requirements of a design. |
| Slew Rate | 0.55 V/µs | 3.6 V/µs | Slew rate limits how fast the output can respond to input changes; significant differences affect large-signal and high-frequency performance. |
| Input Bias Current (Typ) | 1 pA | 1 pA | Low bias current is critical for high-impedance sensor interfaces; matching values indicate similar input loading behavior. |
| Quiescent Current per Channel (Typ) | 0.5 mA | 0.5 mA | Quiescent current impacts power budget; identical per-channel values mean comparable efficiency in battery-powered designs. |
| Operating Temperature Range | -40°C to 125°C | -40°C to 125°C | Matching temperature ranges ensure both parts are suitable for the same environmental conditions and reliability requirements. |

Frequently asked questions
What are the main differences between the TLC2262CDR and the TLC2274MDRG4?
The TLC2262CDR is a dual operational amplifier, while the TLC2274MDRG4 is a quad operational amplifier. Both are from Texas Instruments' TLC226x/227x family of LinCMOS rail-to-rail output op amps. The TLC2262CDR comes in an SOIC-8 package, and the TLC2274MDRG4 comes in an SOIC-14 package. The TLC2274MDRG4 is also specified with an extended temperature range and is qualified for automotive applications per AEC-Q100.
Do the TLC2262CDR and TLC2274MDRG4 share the same electrical performance per amplifier?
Yes. Both devices are based on the same LinCMOS operational amplifier core, so per-channel specifications such as input offset voltage, input bias current, supply current per channel, gain bandwidth product, and slew rate are essentially identical. The primary differences are channel count, package, and qualification grade.
Can the TLC2262CDR be used as a drop-in replacement for one channel of the TLC2274MDRG4?
No. The TLC2262CDR is a dual op amp in an SOIC-8 package, while the TLC2274MDRG4 is a quad op amp in an SOIC-14 package. They are not pin-compatible, and the TLC2262CDR cannot directly replace a single channel of the TLC2274MDRG4 without a redesign of the PCB layout and pin connections.
What are the supply voltage ranges for the TLC2262CDR and TLC2274MDRG4?
Both devices operate from a single supply or split supplies with a total supply voltage range of 2.2 V to 16 V. This wide operating range makes them suitable for battery-powered and industrial applications.
Are the TLC2262CDR and TLC2274MDRG4 rail-to-rail input or output devices?
Both devices feature rail-to-rail output swing. The input common-mode voltage range includes the negative rail but does not extend to the positive rail. They are not rail-to-rail input devices.
What is the operating temperature range for the TLC2262CDR and TLC2274MDRG4?
The TLC2262CDR is specified for operation over the commercial temperature range of 0°C to 70°C. The TLC2274MDRG4 is specified for the extended industrial temperature range of –40°C to 125°C and is AEC-Q100 qualified for automotive use.
What are the package and pin count differences between the TLC2262CDR and TLC2274MDRG4?
The TLC2262CDR is supplied in an 8-pin SOIC package (SOIC-8). The TLC2274MDRG4 is supplied in a 14-pin SOIC package (SOIC-14). The TLC2274MDRG4 has four independent op amp channels, while the TLC2262CDR has two.
Are the TLC2262CDR and TLC2274MDRG4 suitable for automotive applications?
The TLC2274MDRG4 is AEC-Q100 qualified and specified for the extended temperature range of –40°C to 125°C, making it suitable for automotive applications. The TLC2262CDR is a commercial-grade device with a 0°C to 70°C temperature range and is not AEC-Q100 qualified.
What are the typical quiescent current specifications for the TLC2262CDR and TLC2274MDRG4?
The TLC2262CDR typically draws 1.5 mA per channel at 5 V. The TLC2274MDRG4 has a similar per-channel quiescent current. Because the TLC2274MDRG4 contains four channels, its total quiescent current is approximately twice that of the TLC2262CDR under identical supply and load conditions.
