MC74HC4538A - Dual Precision Monostable Multivibrator
MOTOROLA SEMICONDUCTOR TECHNICAL DATA Dual Precision Monostable Multivibrator (Retriggerable, Resettable) The MC54/74HC4538A is identical in pinout to the MC14538B.
The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.
This dual monostable multivibrator may be triggered by either the positive or the negative edge of an input pulse, and produces a precision output pulse over a wide range of pulse widths.
Because the device ha
