MC74HC4538A_16 Datasheet, PDF (1/14 Pages) ON Semiconductor – Dual Precision Monostable Multivibrator

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, R_x and C_x. 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
