74LVC2T45; 74LVCH2T45

Dual supply translating transceiver; 3-state

Rev. 03 — 19 January 2010

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 data

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.

2. Features

Wide supply voltage range:

CC(A)

: 1.2 V to 5.5 V

CC(B)

: 1.2 V to 5.5 V

High noise immunity

Complies with JEDEC standards:

JESD8-7 (1.2 V to 1.95 V)

JESD8-5 (1.8 V to 2.7 V)

JESD8C (2.7 V to 3.6 V)

JESD36 (4.5 V to 5.5 V)

ESD protection:

HBM JESD22-A114E Class 3A exceeds 4000 V

MM JESD22-A115-A exceeds 200 V

CDM JESD22-C101C exceeds 1000 V

Maximum data rates:

420 Mbps (3.3 V to 5.0 V translation)

210 Mbps (translate to 3.3 V))

140 Mbps (translate to 2.5 V)

75 Mbps (translate to 1.8 V)

60 Mbps (translate to 1.5 V)
