Pinout
The TLC556CDR is a dual timer IC in a 14-pin SOIC package. It consists of two independent 555 timers in a single chip, sharing power (VCC, pin 14) and ground (GND, pin 7).
Key Pin Functions:
- Triggers (pins 2 & 12): Start timing when voltage falls below 1/3 VCC.
- Outputs (pins 5 & 9): Deliver high/low signals based on timer states.
- Thresholds (pins 6 & 8): End timing when voltage exceeds 2/3 VCC.
- Discharge (pins 1 & 13): Discharge external capacitors.
- Control Voltage (pins 3 & 11): Adjust timing thresholds (optional).
- Resets (pins 4 & 10): Force reset when pulled low.
Operates at 2–15V, suitable for precision timing, pulse generation, and oscillation. Compact and efficient for space-constrained designs.
