Description

The ST2378E is an 8-bit, dual supply,

bi-directional level translator with ±15kV ESD-

protection on I/Os at V

interface data transfer between low-voltage

ASICs/PLDs and higher voltage systems.

Externally applied voltage, V

levels at both sides with range specified as

1.71V ≤ V

proper operation, V

VL.

Utilizing a transmission-gate-based design, this

device allows bi-directional asynchronous data

transfer, which means each channel is allowed to

have either V

direction independently and no direction pin is

required. ST2378E operates at guaranteed data

rate of 13Mbps over the entire specified operating

voltage range.

Among the other features is included the OE pin

which allows disable-mode operation whereby

current consumption is reduced to less than 1µA.
