ST2378E:8-Bit Level Translator with 15kV ESD Protection

The ST2378E device is an 8-bit, dual supply,bidirectional level translator with ±15 kV ESD protection on I/Os at VCCside. It is designed to interface data transfer between low voltage ASICs/PLDs and higher voltage systems. Externally applied voltage, VCCand VL, set logic levels at both sides with the range specified as 1.71 V ≤ VL≤ 5.5 V and VL≤ VCC≤ 5.5 V. For proper operation, VCCshould be set higher than VL.

Utilizing a transmission-gate-based design, this device allows bidirectional asynchronous data transfer, which means each channel is allowed to have either VCCto VLor VLto VCCdata transfer direction independently and no direction pin is required. The ST2378E device operates at a guaranteed data rate of 13 Mbps over the entire specified operating voltage range.

Among the other features, the OE pin allows disablemode operation whereby current consumption is reduced to less than 1 μA.
