74VHCT540A Octal Buffer/Line Driver with 3-STATE Outputs May 2007 74VHCT540A Octal Buffer/Line Driver with 3-STATE Outputs Features ■ High Speed: tPD = 5.4ns (Typ.) at VCC = 5V ■ Low Power Dissipation: ICC = 4µA (Max.) at TA = 25°C ■ Power down protection is provided on all inputs and tm General Description The VHCT540A is an advanced high-speed CMOS device fabricated with silicon gate CMOS technology. It achieves the high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. The VHCT540A is an octal buffer/line driver designed to be employed as memory and address drivers, clock drivers and bus oriented transmitter/receivers. This device is similar in function to the VHCT240A while providing flow-through architecture (inputs on opposite side from outputs). This pinout arrangement makes this device especially useful as an output port for microprocessors, allowing ease of layout and greater PC board density. Protection circuits ensure that 0V to 7V can be applied to the input and output(1) pins without regard to the supply voltage. This device can be used to interface 3V to 5V systems and two supply systems such as battery backup. This circuit prevents device destruction due to mismatched supply and input voltages. Note: 1.
