GENERAL DESCRIPTION
The 74HC/HCT5555 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A.
FEATURES
? Positive and negative edge triggered
? Retriggerable or non-retriggerable
? Programmable delay
minimum: 100 ns
maximum: depends on input
frequency and division ratio
? Divide-by range of 2 to 224
? Direct reset terminates output
pulse
? Very low power consumption in
triggered start mode
? 3 oscillator operating modes:
– RC oscillator
– Crystal oscillator
– External oscillator
? Device is unaffected by variations
in temperature and VCC when using
an external oscillator
? Automatic power-ON reset
? Schmitt trigger action on both
trigger inputs
? Direct drive for a power transistor
? Low power consumption in active
mode with respect to TTL type
timers
? High precision due to digital timing
? Output capability: 20 mA
? ICC category: MSI.
APPLICATIONS
? Motor control
? Attic fan timers
? Delay circuits
? Automotive applications
? Precision timing
? Domestic appliances.
