LM556 - Dual Timer

Description

The LM556 Dual timing circuit is a highly stable controller capable of producing accurate time delays or oscillation.

The 556 is a dual 555.

Timing is provided by an external resistor and capacitor for each timing function.

LM556 Dual Timer March 2000 LM556 Dual Timer General Description The LM556 Dual timing circuit is a highly stable controller capable of producing accurate time delays or oscillation. The 556 is a dual 555. Timing is provided by an external resistor and capacitor for each timing function. The two timers operate independently of each other sharing only VCC and ground. The circuits may be triggered and reset on falling waveforms. The output structures may sink or source 200mA. Features n n n n n n n n n Direct replacement for SE556/NE556 Timing from microseconds through hours Operates in both astable and monostable modes Replaces two 555 timers Adjustable duty cycle Output can source or sink 200mA Output and supply TTL compatible Temperature stability better than 0.
