Product Change Notification
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 Qbar 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
  • Pb-Free Packages are Available*
