74LVC2T45; 74LVCH2T45

Dual supply translating transceiver; 3-state

Rev. 8 — 29 March 2013

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.

2. Features and benefits

 Wide supply voltage range:

 V_CC(A): 1.2 V to 5.5 V

 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-A114F Class 3A exceeds 4000 V

 MM JESD22-A115-A exceeds 200 V

 CDM JESD22-C101E 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)
