Dual Precision Monostable Multivibrator (Retriggerable, Resettable)

ON Semiconductor 

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 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.

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. 7 A

• Chip Complexity: 145 FETs or 36 Equivalent Gates

• NLV Prefix for Automotive and Other Applications Requiring

Unique Site and Control Change Requirements; AEC−Q100

Qualified and PPAP Capable

• These Devices are Pb−Free, Halogen Free and are RoHS Compliant
