TC74VHCT32AF

The TC74VHCT32AF is a type of advanced high speed input ot gate fabricated with sillicon gate. It gains the high spe ed operation similar to equivalent bipolar schoottky TTL when keeping the CMOS low power dissipation. The internal circuit is composed of 4 stages consisting of buffer output, which offer high noise immunity and stable output. The in put voltage are compatible with TTL input voltage.

Features of TC74VHCT32AF are: (1)high speed: tpd=3.8ns(typ) at VCC=5V; (2)low power dissipation: ICC=2uA(max) at Ta=25°C; (3)compatible with TTL outputs: VIL=0.8V(max);(4)power down protection is provided on all inputs and outputs; (5)balanced propagation delays: tpLH=tpHL; (6)low noise: VOLP=0.8V(max); (7)pin and function compatible with the 74 series 32 type.

The absolute maximum ratings and recommeded operating conditions of the TC74VHCT32AF can be summarized as: (1)supply voltage range:-0.5V to 7.0V; (2)DC input voltage:-0.5V to 7.0V; (3)DC output voltage:-0.5V to 7.0V; (4)in put diode current:-20mA; (5)output diode current±20mA;(6)DC output current:±20mA; (7)DC Vcc/ground current:±50mA; (8)power dissipation: 180mW; (9)storage temperature:-65°C to 150°C. Recommeded operating conditions: (1)supply voltage: 4.5V to 5.5V; (2)input voltage: 0V to 5.5V; (3)output voltage: 0V to 5.5V; (4)operating temperatur e:-40°C to 85°C; (5)input rise and fall time: 0ns/V to 20ns/V, etc.
