Description

The SN74LXCH8T245 is an 8-bit, dual-supply noninverting bidirectional voltage level translation device with bus-hold circuitry. Ax pins and control pins (DIR andOE) are referenced to VCCAlogic levels, and Bx pins are referenced to VCCBlogic 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 whenOEis set to low. WhenOEis set to high, both Ax and Bx pins are in the high-impedance state. SeeDevice Functional Modesfor a summary of the operation of the control logic.
