Pinout
The TLC555IDR is a CMOS version of the classic 555 timer IC, packaged in an 8-pin SOIC (D).
Pin Functions:
1. GND – Ground
2. TRIG – Trigger input (starts timing when < 1/3 VCC)
3. OUT – Timer output
4. RESET – Active-low reset (must be high for operation)
5. CTRL – Control voltage (bypass with capacitor for stability)
6. THRES – Threshold input (ends timing when > 2/3 VCC)
7. DISCH – Discharge (connects to ground during discharge phase)
8. VCC – Supply voltage (2V–15V)
Key Features:
- Low power consumption (CMOS-based)
- Operates in monostable, astable, or bistable modes
- Compatible with standard 555 timers but more efficient
Applications: Timing, pulse generation, and oscillation circuits.
