Dual timer
Product specification
NE/SA/SE556/NE556-1
DESCRIPTION
Both the 556 and 556-1 Dual Monolithic timing circuits are highly
stable controllers capable of producing accurate time delays or
oscillation. The 556 and 556-1 are 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
Turn-off time less than 2µs (556-1)
Maximum operating frequency >500kHz (556-1)
Timing from microseconds to hours
Replaces two 555 timers
Operates in both astable and monostable modes
High output current
Adjustable duty cycle
TTL compatible
Temperature stability of 0.005%/°C
SE556-1 compliant to MIL-STD or JAN
