The 74VHCT244A is an advanced high speed CMOS OCTAL BUS BUFFER (3-STATE) fabricated with sub-micron silicon gate and double-layer metal wiring C²MOS technology. G output enable governs four BUS BUFFERs.

This 74VHCT244A 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.

All inputs and outputs of the 74VHCT244A are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
