General description

The 74LVC2T45; 74LVCH2T45 are dual bit, dual supply translating transceivers with

3-state outputs that enable bidirectional level translation. They feature two data

input-output ports (nA and nB), a direction control input (DIR) and dual supply pins (VCC(A)

and VCC(B)). Both VCC(A) and VCC(B) can be supplied at any voltage between 1.2 V and

5.5 V making 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 nA and DIR are referenced to VCC(A) and

pins nB are referenced to VCC(B). A HIGH on DIR allows transmission from nA to nB and a

LOW on DIR allows transmission from nB to nA.

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 74LVCH2T45 holds unused or floating data inputs at a valid

logic level.
