20-bit dual supply translating transceiver with configurable

voltage translation; 3-state

Rev. 4 — 14 December 2011

Product data sheet

1. General description

The 74AVCH20T245 is a 20-bit, dual supply transceiver that enables bi-directional voltage

level translation. The device can be used as two 10-bit transceivers or as a single 20-bit

transceiver. It features four 10-bit input-output ports (1An, 1Bn and 2An, 2Bn), two output

enable inputs (nOE), two direction inputs (nDIR) and dual supplies (V_CC(A)and V_CC(B)).

_CC(A)and V_CC(B)can be independently supplied at any voltage between 0.8 V and 3.6 V

making the device suitable for bi-directional voltage level translation between any of the

low voltage nodes: 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V and 3.3 V. The 1An and 2An ports, nOE

and nDIR are referenced to V_CC(A), the 1Bn and 2Bn ports are referenced to V_CC(B). A

HIGH on a 1DIR allows transmission from 1An to 1Bn and a LOW on 1DIR allows

transmission from 1Bn to 1An. A HIGH on nOE causes the outputs to assume a HIGH

impedance OFF-state.

The device is 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, all output ports will assume a high impedance OFF-state. The bus hold

circuitry on the powered-up side always stays active.

2. Features and benefits

 Wide supply voltage range:

 V_CC(A): 0.8 V to 3.6 V

 V_CC(B): 0.8 V to 3.6 V

 Complies with JEDEC standards:

 JESD8-12 (0.8 V to 1.3 V)

 JESD8-11 (0.9 V to 1.65 V)

 JESD8-7 (1.2 V to 1.95 V)

 JESD8-5 (1.8 V to 2.7 V)

 JESD8-B (2.7 V to 3.6 V)

 ESD protection:

 HBM JESD22-A114E Class 3B exceeds 8000 V

 MM JESD22-A115-A exceeds 200 V

 CDM JESD22-C101C exceeds 1000 V

 Maximum data rates:

 380 Mbit/s ( 1.8 V to 3.3 V translation)

 260 Mbit/s ( 1.1 V to 3.3 V translation)

 260 Mbit/s ( 1.1 V to 2.5 V translation)
