概要
Description
Key features of the TLC556MDR include a wide operating voltage range of 2 V to 15 V, low supply current, and a high output drive capability. This makes it suitable for battery-operated devices and portable electronics. The device is capable of providing accurate time delays or oscillation frequencies through external resistors and capacitors.
Offered in a small SOIC-14 package, the TLC556MDR is ideal for applications where space is limited. It is commonly used in pulse generation, frequency division, and timing applications, among others. With its versatility, the TLC556MDR is a reliable choice for engineers seeking an efficient and low-power timing solution.

Pinout
1. GND (Pin 1): Ground reference voltage.
2. TRIG A (Pin 2): Trigger input for Timer A; used to start the timing interval.
3. OUT A (Pin 3): Output for Timer A.
4. RESET A (Pin 4): Reset input for Timer A; active low.
5. CONT B (Pin 5): Control voltage for Timer B; adjusts the threshold and trigger levels.
6. THRES B (Pin 6): Threshold input for Timer B; ends the timing interval when voltage exceeds 2/3 of VCC.
7. DISCH B (Pin 7): Discharge pin for Timer B; used to discharge the timing capacitor.
8. VCC (Pin 8): Supply voltage.
Each timer in the TLC556 can be configured in monostable or astable modes, similar to a standard 555 timer, and operates independently of the other.
