Overview
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 has conditioned trigger inputs, there are no trigger–input rise and fall time restrictions.
The output pulse width is determined by the external timing components, Rx and Cx.
The device has a reset function which forces the Q output low and the Q output high, regardless of the state of the output pulse circuitry.
• Unlimited Rise and Fall Times Allowed on the Trigger Inputs • Output Pulse is Independent of the Trigger Pulse Width • ± 10% Guaranteed Pulse Width Variation from Part to Part (Using th...
