ICM7555
General purpose CMOS timer

August 31, 1994
853-1192 13721
DESCRIPTION
The ICM7555 is a CMOS timer providing significantly improved
performance over the standard NE/SE555 timer, while at the same
time being a direct replacement for those devices in most
applications. Improved parameters include low supply current, wide
operating supply voltage range, low THRESHOLD, TRIGGER, and
RESET currents, no crowbarring of the supply current during output
transitions, higher frequency performance and no requirement to
decouple CONTROL VOLTAGE for stable operation.
The ICM7555 is a stable controller capable of producing accurate
time delays or frequencies.
In the one-shot mode, the pulse width of each circuit is precisely
controlled by one external resistor and capacitor. For astable
operation as an oscillator, the free-running frequency and the duty
cycle are both accurately controlled by two external resistors and
one capacitor. Unlike the bipolar 555 device, the CONTROL
VOLTAGE terminal need not be decoupled with a capacitor. The
TRIGGER and RESET inputs are active low. The output inverter can
source or sink currents large enough to drive TTL loads or provide
minimal offsets to drive CMOS loads.
FEATURES
Exact equivalent in most applications for NE/SE555
Low supply current: 80
μ
A (typ)
Extremely low trigger, threshold, and reset currents: 20pA (typ)
High-speed operation: 500kHz guaranteed
Wide operating supply voltage range guaranteed 3 to 16V over full
automotive temperatures
Normal reset function; no crowbarring of supply during output
transition
Can be used with higher-impedance timing elements than the
bipolar 555 for longer time constants
