74VHC240
Octal Buffer/Line Driver with 3-STATE Outputs
General Description
The VHC240 is an advanced high speed CMOS octal bus
buffer fabricated with silicon gate CMOS technology. It
achieves high speed operation similar to equivalent Bipolar
Schottky TTL while maintaining the CMOS low power dissi-
pation. The VHC240 is an inverting 3-STATE buffer having
two active-LOW output enables. This device is designed to
drive buslines or buffer memory address registers.
An input protection circuit ensures that 0V to 7V can be
applied to the input pins without regard to the supply volt-
age. This device can be used to interface 5V to 3V systems
and two supply systems such as battery backup. This cir-
cuit prevents device destruction due to mismatched supply
and input voltages.
