74VHCT541A Octal Buffer/Line Driver with 3-STATE Outputs June 1997 Revised April 2005 74VHCT541A Octal Buffer/Line Driver with 3-STATE Outputs General Description The VHCT541A 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 VHCT541A 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 VHCT244A 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 (Note 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: Outputs in OFF-state. Features s High Speed: tPD 5.5 ns (typ) at VCC 5V 25qC s Low power dissipation: ICC 4 PA (max) at TA s Power down protection is provided on all inputs and outputs s Pin and function compatible with 74HCT541 Ordering Code: Order Number 74VHCT541AM 74VHCT541ASJ 74VHCT541AMTC 74VHCT541AN Package Number M20B M20D MT……
