Description

The ST2378E is an 8-bit, dual supply,

bi-directional level translator with ±15kV ESD-

protection on I/Os at VCC side. It is designed to

interface data transfer between low-voltage

ASICs/PLDs and higher voltage systems.

Externally applied voltage, VCC and VL, set logic

levels at both sides with range specified as

1.71V

≤ VL ≤ 5.5V and VL ≤ VCC ≤ 5.5V. For

proper operation, VCC should be set higher than

VL.

Utilizing a transmission-gate-based design, this

device allows bi-directional asynchronous data

transfer, which means each channel is allowed to

have either VCC to VL or VL to VCC data transfer

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.
