Pin and function compatible with 74HC240
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 dissipation. 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
voltage. This device can be used to interface 5V to 3V
systems and two supply systems such as battery
backup. This circuit prevents device destruction due to
mismatched supply and input voltages.
Ordering Information
Surface mount packages are also available on Tape and Reel. Specify by appending the suffix letter “X” to the
ordering number. Pb-Free package per JEDEC J-STD-020B.
