ONSEMI MC74HC4538ADG Dual Monostable Multivibrator
The MC74HC4538ADG is a dual precision monostable multivibrator compatible with the MC14538B pinout. It features inputs that are compatible with standard CMOS outputs, with pull-up resistors, and can interface with LSTTL outputs. The device can be triggered by either the positive or negative edge of an input pulse, generating a precise output pulse over a wide range of pulse widths. Its conditioned trigger inputs eliminate the rise and fall time restrictions typically associated with trigger signals. The output pulse width is adjustable via external timing components, Rₓ and Cₓ. Additionally, it includes a reset function that forces the Q output low and the Q output high, regardless of the pulse circuitry state. The device allows unlimited rise and fall times on trigger inputs, and the output pulse duration is independent of trigger pulse width. It directly interfaces with CMOS, NMOS, and TTL logic levels, and boasts high noise immunity. This device complies with JEDEC standard no. 7A, offers a guaranteed ±10% pulse width variation, provides a 10 LSTTL load drive capability, and features a low input current of 1 mA.
