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.
