Overview
74AVCH16T245 16-bit dual supply translating transceiver with configurable voltage translation; 3-state Rev.
01 — 14 October 2009 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 (VCC(A) and VCC(B)) for voltage translation and two 8-bit input-output ports (nAn, nBn) each with its own output enable (nOE) and send/receive (nDIR) input for direction control.
VCC(A) and VCC(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 IOFF.
The IOFF circuitry disables the output, preventing any damaging backflow current through the device when it is powered down.
In suspend mode when either VCC(A) or VCC(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.
