74AVC16T245-Q100
16-bit dual supply translating transceiver with configurable
voltage translation; 3-state
Rev. 2 — 14 January 2019 Product data sheet
1. General description
The 74AVC16T245-Q100 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 port has its own output enable (nOE) and send/receive (nDIR) input for
direction control. V
CC(A)
and V
CC(B)
can be independently supplied with any voltage between 0.8 V
and 3.6 V. This flexibility makes 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.
This product has been qualified to the Automotive Electronics Council (AEC) standard Q100
(Grade 1) and is suitable for use in automotive applications.
