ST2378E 8-Bit Level Translator with 15kV ESD Protection

The ST2378E is an 8-bit, dual supply, bi-directional level translator with ±15kV ESDprotection 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
