SN54AHCT123AF

The SN54AHCT123AF 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.

Features of the SN54AHCT123AF are:(1) Inputs Are TTL-Voltage Compatible; (2) Schmitt-Trigger Circuitry On A, B, and CLR Inputs for Slow Input Transition Rates; (3) Edge Triggered From Active-High or Active-Low Gated Logic Inputs; (4) Retriggerable for Very Long Output Pulses; (5) Overriding Clear Terminates Output Pulse; (6) Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II; (7) ESD Protection Exceeds JESD 22  2000-V Human-Body Model (A114-A)  200-V Machine Model (A115-A)  1000-V Charged-Device Model (C101).

The absolute maximum ratings of the SN54AHCT123AF can be summarized as:(1)Supply voltage range, VCC:-0.5 V to 7 V; (2)Input voltage range, VI: -0.5 V to 7 V; (3)Output voltage range, VO:-0.5 V to VCC + 0.5 V; (4)Input clamp current, IIK (VI0): -20 mA ; (5)Output clamp current, IOK (VO < 0 or VO > VCC):  ±20 mA; (6)Continuous output current, IO (VO = 0 to VCC):±25 mA; (7)Continuous current through VCC or GND:±50 mA; (8)Storage temperature range, Tstg :-65°C to 150°C.
