MC74HC4538A: Dual Precision Monostable Multivibrator

Description: The MC74HC4538A is identical in pinout to the MC14...
  • 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
