Overview

74LVC1T45-Q100; 74LVCH1T45-Q100 Dual supply translating transceiver; 3-state Rev.
5 — 10 February 2022 Product data sheet 1.
General description The 74LVC1T45-Q100; 74LVCH1T45-Q100 are single bit, dual supply transceivers with 3-state outputs that enable bidirectional level translation.
They feature two 1-bit input-output ports (A and B), a direction control input (DIR) and dual supply pins (VCC(A) and VCC(B)).
Both VCC(A) and VCC(B) can be supplied with any voltage between 1.
2 V and 5.
5 V.
This flexibility makes the device suitable for translating between any of the low voltage nodes (1.
2 V, 1.
5 V, 1.
8 V, 2.
5 V, 3.
3 V and 5.
0 V).
Pins A and DIR are referenced to VCC(A) and pin B is referenced to VCC(B).
A HIGH on DIR allows transmission from A to B and a LOW on DIR allows transmission from B to A.
The devices are fully specified for partial power-down applications using IOFF.
The IOFF circuitry disables the output, preventing any damaging backflow current through the device when it is powered down.
In suspend mode when either VCC(A) or VCC(B) are at GND level, both A port and B port are in the high-impedance OFF-state.
Active bus hold circuitry in the 74LVCH1T45-Q100 holds unused or floating data inputs at a valid logic level.
This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications.
