TC74VHCT74AF集成电路（IC）的触发器规格书PDF中文资料

Dual D-Type Flip-Flop with Preset and Clear

The TC74VHCT74 is an advanced high speed CMOS D-FLIP FLOP fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation.

特性 Features

• High speed: fmax = 160 MHz (typ.) at VCC = 5 V

• Low power dissipation: ICC = 2 μA (max) at Ta = 25°C

• Compatible with TTL outputs: VIL = 0.8 V (max)

VIH = 2.0 V (min)

• Power down protection is provided on all inputs and outputs

• Balanced propagation delays: tpLH ∼ − tpHL

• Pin and function compatible with the 74 series

(74AC/HC/F/ALS/LS etc.) 74 type.
