HD74HC423A Dual Retriggerable Monostable Multivibrators REJ03D0626-0200 (Previous ADE-205-505) Rev.2.00 Mar 30, 2006 Description This multivibrator features output-pulse-duration control by two methods. The basic pulse duration is programmed by selection of external resistance and capacitance values. Once triggered, the basic pulse duration may be extended by retriggering the gated low-level-active (A) or high-level-active (B) inputs, or be reduced by use of the overriding clear. The B input is a Schmitt trigger enabling jitter-free triggering from input signals with slow transition rates. Features High Speed Operation High Output Current: Fanout of 10 LSTTL Loads Wide Operating Voltage: VCC = 2 to 6 V Low Input Current: 1 µA max Low Quiescent Supply Current Ordering Information Part Name Package Type Package Code (Previous Code) Package Abbreviation HD74HC423AP DILP-16 pin PRDP0016AE-B (DP-16FV) P HD74HC423AFPEL SOP-16 pin (JEITA) PRSP0016DH...
