Key electrical and mechanical differences between the two devices
| Parameter | AD8174ARZ | AD8174AR | Why it matters |
|---|---|---|---|
| Manufacturer | Analog Devices Inc. | Analog Devices Inc. | Same manufacturer ensures consistent design, documentation, and support. |
| Function / Type | 4-channel video multiplexer-amplifier with buffered outputs | 4-channel video multiplexer-amplifier with buffered outputs | Identical core function confirms the parts are functionally interchangeable in the same circuit role. |
| Package / Case | 14-lead SOIC (R-14) | 14-lead SOIC (R-14) | Same package footprint allows drop-in board replacement without layout changes. |
| Supply Voltage Range | ±5 V to ±15 V (dual supply) | ±5 V to ±15 V (dual supply) | Matching supply range ensures compatibility with the existing power design. |
| -3 dB Bandwidth | 250 MHz (typical) | 250 MHz (typical) | Bandwidth determines video signal fidelity and is critical for high-speed video switching applications. |
| Slew Rate | 1000 V/µs (typical) | 1000 V/µs (typical) | Slew rate affects large-signal transient response and video pulse fidelity. |
| Number of Channels | 4 | 4 | Channel count must match to preserve the multiplexing architecture of the design. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Same temperature range ensures equivalent environmental robustness. |
| RoHS / Lead-Free Status | RoHS compliant, lead-free (Z suffix) | Non-RoHS, contains lead | RoHS compliance affects regulatory compliance and solder process compatibility; the Z suffix denotes the lead-free variant. |
| Packaging / Ordering Suffix | Z = lead-free, RoHS-compliant SOIC | No Z suffix = leaded SOIC | The suffix distinguishes lead-free from leaded parts, which matters for procurement and environmental compliance. |

Frequently asked questions
What is the difference between AD8174ARZ and AD8174AR?
The AD8174ARZ is the RoHS-compliant, lead-free (Pb-free) version of the AD8174AR. Both are the same 4-channel buffered video multiplexer from Analog Devices in a 14-lead SOIC package; the "Z" suffix denotes the RoHS-compliant packaging option, while the AD8174AR is the non-RoHS (leaded) variant.
Are AD8174ARZ and AD8174AR functionally and electrically identical?
Yes. Both parts share the same die and datasheet specifications for the AD8174: 4-channel multiplexer with buffered outputs, 250 MHz -3 dB bandwidth, 1000 V/µs slew rate, and ±5 V or single-supply operation. The only documented difference is the RoHS/lead-free package finish indicated by the "Z" suffix.
Can AD8174ARZ be used as a drop-in replacement for AD8174AR?
Yes, in most cases. Both are supplied in the same 14-lead SOIC (R-14) package with identical pinout and land pattern, so the AD8174ARZ is a form-fit-function replacement for the AD8174AR. Designs requiring RoHS compliance should use the AD8174ARZ.
What is the function of the AD8174 multiplexer?
The AD8174 is a 4-to-1 analog multiplexer with an internal output buffer, intended for video and high-speed signal routing. It selects one of four inputs via two binary address lines and drives a buffered output, making it suitable for RGB/video switching and signal selection applications.
What supply voltage does the AD8174ARZ/AD8174AR require?
The AD8174 operates on dual supplies of ±5 V or a single supply of +5 V to +12 V, per the Analog Devices datasheet. Verify the exact recommended operating conditions in the current datasheet before design.
Does the "Z" suffix affect electrical performance?
No. The "Z" suffix in Analog Devices part numbering designates RoHS compliance (lead-free termination finish). It does not change the electrical specifications, which remain identical to the non-Z AD8174AR.
Which part should be specified for a new RoHS-compliant design?
The AD8174ARZ should be specified for new designs requiring RoHS compliance. The AD8174AR (non-Z) is the legacy non-RoHS option and may be subject to restricted availability or obsolescence in some markets.
