74HC4538 - Dual retriggerable precision monostable multivibrator

General Description

Each multivibrator

Key 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 short. The HD74HC4538 is retriggerable. That is, it may be triggered repeatedly while their outputs are generating a pulse and the pulse will be extended. Pulse width stability over a wide range of temperature. The output pulse equation is simply: tw = 0.7 (R) (C). Features.
