The 74VHCV540FT and 74VHCV541FT are Advanced high speed CMOS OCTAL BUS BUFFERs fabricated with silicon gate CMOS technology. They achieve the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. The 74VHCV540FT is an inverting type, and the 74VHCV541FT is a non-inverting type. When either G1 or G2 are high, the Terminal outputs are in the high-impedance state. Input pin have hysteresis between the positive-going and negative-going thresholds. Thus the 74VHCV540FT and 74VHCV541FT are capable of squaring up transitions of slowly changing input signals and provides an improved noise immunity. 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.

Wide operating temperature range: Topr = -40 to 125 

High speed: tpd = 4.1 ns (typ.) at VCC = 5.0 V

Low power dissipation: ICC = 2.0 μA (max) at Ta = 25 

Wide operating voltage range: VCC(opr) = 1.8 V to 5.5 V

Output current: |IOH|/IOL = 16 mA (min)(VCC = 4.5 V)

Power-down protection provided on all inputs and outputs.

Pin and function compatible with the 74 series (74AC/HC/AHC/LV etc.) 540 or 541 type
