74VHCT540A  
Octal Buffer/Line Driver with 3-STATE Outputs  
Protection circuits ensure that 0V to 7V can be applied to  
General Description  
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 mis-  
matched supply and input voltages.  
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 dissi-  
pation.  
Note 1: Outputs in OFF-STATE  
The VHCT540A is an octal buffer/line driver designed to be  
employed as memory and address drivers, clock drivers  
and bus oriented transmitter/receivers.  
Features  
■ High Speed:  
t
PD = 5.4 ns (typ) at VCC = 5V  
CC = 4 µA (max) at TA = 25°C  
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.  
■ Low Power Dissipation:  
I
■ Power down protection is provided on all inputs and  
outputs  
■ Pin and function compatible with 74HCT540
