µPC617
Timer IC
Timer circuit
Overview
The µPC617 is a powerful integrated circuit. Adding a few external parts to it can turn it into various types of timing signal generators, such as monostable and astable multivibrators. It has trigger, threshold, and control pins.
Inputting a signal to the reset pin can stop the circuit operation easily. In addition, the output can sink current as high as 200 mA (maximum). So, it can be used to drive relays and lamps.
Features
- Supply voltage : 4.5 to 16 V
- Circuit current (VCC = 5 V) : 3 mA
- Output current capacity : 200 mA
- Temperature stability : 0.005%/°C
- Rising and falling time : 100 ns
- Monostable and astable oscillation
- Interfacing directly with TTL-level signals
- Variable duty cycle
