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.
