Description

General part information

SN74LXC1T45 Series

The SN74LXC1T45 is a 1-bit, dual-supply noninverting bidirectional voltage level translation device. The I/O pin A and control pin (DIR) are referenced to VCCAlogic levels, and the I/O pin B are referenced to VCCBlogic levels. The A pin is able to accept I/O voltages ranging from 1.1 V to 5.5 V, while the B pin 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. SeeDevice Functional Modesfor a summary of the operation of the control logic.
