74HC423
Schematic symbol
Dual retriggerable monostable multivibrator (one-shot): Each half makes an output pulse whose length is set by a capacitor between Cext and Rext/Cext and a resistor from Rext/Cext to VCC. It triggers on a falling edge of A while B is high, or a rising edge of B while A is low, and a new trigger during the pulse stretches it. RD low ends the pulse. Like the 74HC123, but a rising edge on RD does not start a pulse. Same pinout as the 74HC123.
