16-bit dual supply translating transceiver with configurable

voltage translation; 3-state

Rev. 3 — 9 June 2011

Product data sheet

1. General description

The 74AVC16T245 is a 16-bit transceiver with bidirectional level voltage translation and

3-state outputs.The device can be used as two 8-bit transceivers or as a 16-bit

transceiver. It has dual supplies (V_CC(A)and V_CC(B)) for voltage translation and four 8-bit

input-output ports (nAn and nBn) each with its own output enable (nOE) and send/receive

(nDIR) input for direction control. V_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 low voltage translation

between any of the following voltages: 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V and 3.3 V. A HIGH

on nDIR selects transmission from nAn to nBn while a LOW on nDIR selects transmission

from nBn to nAn. 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, both nAn and nBn are in the high-impedance OFF-state.

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-A114F Class 3B exceeds 8000 V

 MM JESD22-A115-A exceeds 200 V

 CDM JESD22-C101D exceeds 1000 V

 Maximum data rates:

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

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

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

 200 Mbit/s ( 1.1 V to 1.8 V translation)

 150 Mbit/s ( 1.1 V to 1.5 V translation)
