Description
The ST2378E device is an 8-bit, dual supply,
bidirectional level translator with ±15 kV 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
1.71 V ≤ VL ≤ 5.5 V and VL ≤ VCC ≤ 5.5 V.
For proper operation, VCC should 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 VCC to VL or VL to VCC data transfer
direction independently and no direction pin is
required. The ST2378E device operates at
guaranteed data rate of 13 Mbps over the entire
specified operating voltage range.
Among the other features there is included the
OE pin which allows disable mode operation
whereby current consumption is reduced to less
than 1 µA.
