74AVCH16T245

16-bit dual supply translating transceiver with configurable

voltage translation; 3-state

Rev. 6 — 3 April 2019

Product data sheet

1. General description

The 74AVCH16T245 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, 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_OFFcircuitry

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 and B

outputs are in the high-impedance OFF-state. The bus-hold circuitry on the powered-up side

always stays active.

The 74AVCH16T245 has active bus hold circuitry which is provided to hold unused or floating

data inputs at a valid logic level. This feature eliminates the need for external pull-up or pull-down

resistors.
