74VHCT244AT

OPERATING VOLTAGERANGE:

V_CC(OPR)= 4.5V to 5.5V

PIN AND FUNCTION COMPATIBLEWITH

74 SERIES244

This device is designed to be used with 3 state

memory address drivers, etc.

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.

■

IMPROVED LATCH-UP IMMUNITY

LOWNOISEV_OLP= 0.9V(Max.)

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.

DESCRIPTION

The 74VHCT244A is an advanced high speed

CMOS OCTAL BUS BUFFER (3-STATE)

fabricated with sub-micron silicon gate and

double-layermetal wiring C²MOS technology.

G output enable governs four BUS BUFFERs.
