Product data sheet

General description
The 74AVC4TD245PW is a 4-bit, dual supply transceiver that enables bidirectional level
translation. It features eight 1-bit input-output ports (An and Bn), four direction control
inputs (DIR1, DIR2, DIR3 and DIR4), an output enable input (OE) and dual supply pins
(V
CC(A)
and V
CC(B)
). Both V
CC(A)
and V
CC(B)
can be supplied at any voltage between
0.8 V and 1.95 V for translating between the 0.8 V, 1.2 V, 1.5 V and 1.8 V supply voltage
nodes or 1.1 V to 3.6 V for translating between the 1.2 V, 1.5 V, 1.8 V, 2.5 V and 3.3 V
supply voltage nodes. Pins An, OE and DIRn are referenced to V
CC(A)
and pins Bn are
referenced to V
CC(B)
. A HIGH on DIRn allows transmission from An to Bn and a LOW on
DIRn allows transmission from Bn to An. The output enable input (OE) can be used to
disable the outputs so the buses are effectively isolated.
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 An and Bn are in the high-impedance OFF-state.
