DESCRIPTION
The 74VHCT126A is an advanced high-speed
CMOS QUAD BUS BUFFERS fabricated with
sub-micron silicon gate and double-layer metal
wiring C
The device requires the 3-STATE control input G
to be set low to place the output in to the high
impedance state.

Table 1: Order Codes
Power down protection is provided on all inputs
and outputs 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 since all
inputs are equipped with TTL threshold.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
