1. General description
The 74AVC8T245-Q100 is an 8-bit, dual supply transceiver that enables bidirectiona l level
translation. It features two 8-bit input-output ports (An and Bn), a direction control input
(DIR), 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 DIR are referenced to V
CC(A)
and pins Bn are
referenced to V
CC(B)
. A HIGH on DIR allows transmission from An to Bn and a LOW on
DIR 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.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.
