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 (VCC(A) and VCC(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. 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 nAn and nBn are in the high-impedance OFF-state.
