1. General description

2. Features and benefits

The 74LVC1T45; 74LVCH1T45 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 (V

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 V

to V

transmission from B to A.

The devices are fully specified for partial power-down applications using I

circuitry disables the output, preventing any damaging backflow current through the

device when it is powered down. In suspend mode when either V

GND level, both A port and B port are in the high-impedance OFF-state.

Active bus hold circuitry in the 74LVCH1T45 holds unused or floating data inputs at a valid

logic level.
