Description
The ST2378E is an 8-bit, dual supply,
bi-directional level translator with ±15kV 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_CC and V_L, set logic
levels at both sides with range specified as
1.71V ≤ V_L ≤ 5.5V and V_L ≤ V_CC ≤ 5.5V. For
proper operation, V_CC 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 V_CC to V_L or V_L to V_CC 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.
