Description

The TC74VHCT540A and TC74VHCT541AFT are advanced high speed CMOS OCTAL BUS BUFFERs fabricated with silicon gate C2MOS technology. They achieve the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation.The TC74VHCT540A is an inverting type and, the TC74VHCT541AFT is a non-inverting type.When either G1 or G2 are high, the terminal outputs are in the high-impedance state.The input voltage are compatible with TTL output voltage.These devices may be used as a level converter for interfacing 3.3 V to 5 V system.Input protection and output circuit ensure that 0 to 5.5 V can be applied to the input and output (Note) pins without regard to the supply voltage. These structure prevents device destruction due to mismatched supply and input/output voltages such as battery back up, hot board insertion, etc. TC74VHCT541AFT 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.
