TC74VHCT541AF Datasheet

Silicon Monolithic


The TC74VHCT540A and 541A are advanced high speed CMOS OCTAL BUS BUFFERs fabricated with silicon gate C2 MOS technology. They achieve the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. TC74VHCT541AF Features • High speed: tpd= 5.4 ns (typ.) at VCC= 5 V • Low power dissipation: ICC= 4 μA (max) at Ta = 25°C • Compatible with TTL inputs: 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• Low noise: VOLP= 1.5 V (max) • Pin and function compatible with the 74 series (74AC/HC/F/ALS/LS etc.) 540/541 type.
