74LVC2T45; 74LVCH2T45

Dual supply translating transceiver; 3-state

Rev. 7 — 19 June 2012

Product data sheet

1. General description

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

3-state outputs that enable bidirectional level translation. They feature two 2-bits

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

CC(A)

and V

CC(B)

). Both V

CC(A)

and V

CC(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 V

CC(A)

and

pins nB are referenced to V

CC(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 I

OFF

. The I

OFF

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

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

CC(A)

or V

CC(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.
