DESCRIPTION
The 74VHC240 is an advanced high-speed
CMOS OCTAL BUS BUFFER (3-STATE)
fabricated with sub-micron silicon gate and
double-layer metal wiring C2MOS technology.
G output enable governs four BUS BUFFERs.

(Micro Package)
T
(TSSOP Package)
ORDER CODES :
74VHC240M
74VHC240T
This device is designed to be used with 3 state
memory address drivers, etc.
Power down protection is provided on all inputs
and 0 to 7V can be accepted on inputs with no
regard to the supply voltage. This device can be
used to interface 5V to 3V.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
