(Micro Package)

(TSSOP Package)

ORDER CODES :

74VHC126M

74VHC126T

This device requires the 3-STATE control input G

to be set low to place the output into the high

impedance state.

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.

DESCRIPTION

The 74VHC126 is an advanced high-speed

CMOS QUAD BUS BUFFERS fabricated with

sub-micron silicon gate and double-layer metal

wiring C

MOS technology.
