Description
The ST2378E device is an 8-bit, dual supply,
bidirectional level translator with ±15 kV ESD
protection on I/Os at V
CC
side. It is designed to
interface data transfer between low voltage
ASICs/PLDs and higher voltage systems.
Externally applied voltage, V

levels at both sides with the range specified as

For proper operation, V
CC
should be set higher
than V

.
Utilizing a transmission-gate-based design, this
device allows bidirectional asynchronous data
transfer, which means each channel is allowed to
have either V
CC

L
or V
L
to V
CC
data 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
disable mode operation whereby current
consumption is reduced to less than 1 μA.
