Description

The M54/74HC4538 is a high speed CMOS DUAL MONOSTABLEMULTIVIBRATOR fabricated insilicon gate C2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption. Each multivibrator features both a negative, A, and a positive, B, edge triggered input, either ofwhich can be used as an inhibit input. Also included is a clear input that when taken low resets the one shot. The monostable multivibrators are retriggerable. That is,theymay be triggered reapeatedly while their outputs are generating a pulse and the pulse will be extended. Pulse width stability over a wide range of temperature and supply is achieved using linear CMOS techniques.

The output pulse equation of M74HC4538 is simply : PW = 0.7 (R)(C) where PW is in seconds, R in Ohms, and C is in Farads.

All inputs are equipped with protection circuits against static discharge and transient excess voltage.
