MM74HC4538 Dual Retriggerable Monostable Multivibrator
General Description
The MM74HC4538 high speed monostable multivibrator (one shots) is implemented in advanced silicon-gate
CMOS technology.
They feature speeds comparable to low power Schottky TTL circuitry while retaining the low power and high noise immunity characteristic of
CMOS circuits.
Each multivibrator features both a negative, A, and a positive, B, transition triggered input, either of which can be used as an inhibit input.
Also included is a clear input that when taken low resets the one shot.
The MM74HC4538 is retriggerable.
That is, it...
