General description
The 74AVC4T774 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 3.6 V making the device suitable for translating between any of the low voltage
nodes (0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V and 3.3 V). 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.

(1) This is not a supply pin, the substrate is attached to
this pad using conductive die attach material. There is no
electrical or mechanical requirement to solder this pad.
However if it is soldered the solder land should remain
floating or be connected to GND.
