OPERATING VOLTAGERANGE:

V_CC(OPR)= 2V to 5.5V

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 interface5V to 3V.

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.

PIN AND FUNCTION COMPATIBLEWITH

74 SERIES244

IMPROVED LATCH-UP IMMUNITY

LOWNOISEV_OLP= 0.9V(Max.)

DESCRIPTION

The 74VHC244 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.
