74AVC16T245
16-bit dual supply translating transceiver with configurable
voltage translation; 3-state
Rev. 7 — 14 January 2019 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.
