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 the
Same Test Jig)
Output Drive Capability: 10 LSTTL Loads
Outputs Directly Interface to CMOS, NMOS and TTL
Operating Voltage Range: 3.0 to 6.0 V
Low Input Current: 1.0
