MC74HC4538A
Dual Precision Monostable
Multivibrator (Retriggerable,
Resettable)
The MC74HC4538A 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 triggerâinput 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.
Features
⢠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 mA
⢠High Noise Immunity Characteristic of CMOS Devices
⢠In Compliance with the Requirements Defined by JEDEC Standard
No. 7A
⢠Chip Complexity: 145 FETs or 36 Equivalent Gates
⢠PbâFree Packages are Available*
