Resistors Allow for Floating Control Inputs
High Drive Strength (up to 32 mA at 5 V)
Low Power Consumption
The SN74LXC8T245 is an 8-bit, dual-supply
noninverting bidirectional voltage level translation
device. Ax pins and control pins (DIR and OE) are
referenced to V CCA logic levels, and Bx pins are
referenced to VCCB logic levels. The A port is able to
accept I/O voltages ranging from 1.1 V to 5.5 V, while
the B port can accept I/O voltages from 1.1 V to 5.5 V.
A high on DIR allows data transmission from A to B
and a low on DIR allows data transmission from B to
A when OE is set to low. When OE is set to high, both
Ax and Bx pins are in the high-impedance state. See
Device Functional Modes for a summary of the
operation of the control logic.
