Product Overview

The SN74AHC123APWR is a dual retriggerable Monostable Multivibrator designed for 2 to 5.5V VCC operation. This edge-triggered multivibrator features output pulse-duration control by three methods. In the first method, the A\ input is low and the B input goes high. In the second method, the B input is high and the A\ input goes low. In the third method, the A\ input is low, the B input is high and the clear (CLR\) input goes high. The output pulse duration is programmed by selecting external resistance and capacitance values. The external timing capacitor must be connected between Cext and Rext/Cext (positive) and an external resistor connected between Rext/Cext and VCC. To obtain variable pulse durations, connect an external variable resistance between Rext/Cext and VCC. The output pulse duration also can be reduced by taking CLR\ low. Pulse triggering occurs at a particular voltage level and is not directly related to the transition time of the input pulse.
  • Edge triggered from active-high or active-low gated logic inputs
  • Retriggerable for very long output pulses
  • Overriding clear terminates output pulse
  • Glitch-free power-up reset on outputs
  • Latch-up performance exceeds 100mA per JESD 78, Class II
  • Green product and no Sb/Br
