NE556 – Dual Timer IC

SKU: NE556-DIP14 Categories: ,


NE556 is a dual timer IC, means it has two 555 timer circuit in 14 Pin DIP package. This IC is very useful where you have to generate two different time cycle, like sending burst of 38KHz signal after every 1 Hz time gap. one timer will be tuned at 38KHz and other at 1Hz will triggers first timer.

The threshold (THRES) and trigger (TRIG) levels normally are two-thirds and one-third, respectively, of VCC. These levels can be altered by using the control voltage (CONT) terminal. When the trigger input falls below trigger level, the flip-flop is set and the output goes high. If the trigger input is above the trigger level and the threshold input is above the threshold level, the flip-flop is reset, and the output is low. The reset (RESET) input can override all other inputs and can be used to initiate a new timing cycle. When RESET goes low, the flip-flop is reset and the output goes low. When the output is low, a low-impedance path is provided between the discharge (DISCH) terminal and ground (GND).


This is a direct replacement for SE556/LM556 IC.
