DESCRIPTION
The LVQ240 is a low voltage CMOS OCTAL BUS
BUFFER fabricated with sub-micron silicon gate
and
double-layer
metal
wiring
C
2MOS
T
(TSSOP Package)
technology. It is ideal for low power and low noise
3.3V applications.
It has better speed performance at 3.3V than 5V
LSTTL family combined with the true CMOS low
power consumption.
G output control governs four BUS BUFFERs.
This device is designed to be used with 3 state
memory address drivers, etc.
All inputs
and
outputs are
equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
