74HC4538N

The 74HC4538N is a dual retriggerable precision monostable Multivibrator is a high-speed Si-gate CMOS devices and are pin compatible with low-power Schottky TTL (LSTTL ). The device is specified in compliance with JEDEC standard no-7A. This is a dual retriggerable-resettable monostable multivibrators. Each multivibrator has an active low trigger/retrigger input (nA), an active high trigger/retrigger input (nB), an overriding active low direct reset input (nCD), an output (nQ) and its complement (nQ) and two pins (nREXT/CEXT and nCEXT) for connecting the external timing components CEXT and REXT. Typical pulse width variation over the specified temperature range is ±0.2%. The multivibrator may be triggered by either the positive or the negative edges of the input pulse. The duration and accuracy of the output pulse are determined by the external timing components CEXT and REXT.

• Tolerant of slow trigger rise and fall times
• Separate reset inputs
• Triggering from falling or rising edge
