1 / 21 page SN54AHCT123A, SN74AHCT123A DUAL RETRIGGERABLE MONOSTABLE MULTIVIBRATORS SCLS420G – JUNE 1998 – REVISED APRIL 2003 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Inputs Are TTL-Voltage Compatible D Schmitt-Trigger Circuitry On A, B, and CLR Inputs for Slow Input Transition Rates D Edge Triggered From Active-High or Active-Low Gated Logic Inputs D Retriggerable for Very Long Output Pulses D Overriding Clear Terminates Output Pulse D Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II D ESD Protection Exceeds JESD 22 – 2000-V Human-Body Model (A114-A) – 200-V Machine Model (A115-A) – 1000-V Charged-Device Model (C101) description/ordering information These edge-triggered multivibrators feature 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.
