Description

ST2329 is a level translator providing level shifting

necessary to allow data transfer in a multi-voltage

set the logic levels on either side of the device. It

utilizes transmission gate based design that

allows bidirectional level translation without

control pin.

The ST2329 accepts VL from 1.65V to 3.6V and

transfer between low-voltage ASICs /PLD and

higher voltage system. This device has three-

state output mode that disables all I/Os.

ST2329 supports power-down mode at either of

when one of the supply is off. This feature will

protect the device from current backflow through

the device.
