Features
1. Dual Timer: Combines two independent 555 timer circuits in a single package, allowing for more versatile timing applications.
2. Low Power Consumption: Due to its CMOS design, the TLC556CD offers lower power consumption compared to standard bipolar 555 timers.
3. Wide Supply Voltage Range: Operates from 2 V to 15 V, making it suitable for various applications.
4. High Output Current: Capable of driving up to 200 mA, which allows it to directly drive LEDs, relays, and other devices.
5. Timing Adjustability: Provides precise control over timing functions such as monostable (one-shot) and astable (oscillator) modes with external resistors and capacitors.
6. Temperature Range: Designed to operate over a wide temperature range, typically from 0°C to 70°C for commercial applications.
7. Package Type: Available in a surface-mount SOIC-14 package, ideal for compact designs.
These features make the TLC556CD suitable for a broad range of timing, pulse generation, and oscillator applications.
Pinout
1. GND (Pin 1): Ground reference voltage.
2. TRIG A (Pin 2): Trigger input for Timer A. A low input triggers the operation.
3. OUT A (Pin 3): Output for Timer A. Can sink or source current.
4. RESET A (Pin 4): Reset input for Timer A. A low input resets the timer.
5. CONT A (Pin 5): Control voltage for Timer A. Modifies the threshold and trigger levels.
6. THRES A (Pin 6): Threshold input for Timer A. Ends the timing interval when it exceeds 2/3 of VCC.
7. DISCH A (Pin 7): Discharge pin for Timer A. Used for timing capacitor discharge.
8. VCC (Pin 8): Supply voltage.
The TLC556CD is favored for its low power consumption and wide operating voltage range, making it ideal for battery-powered applications.
