1. General description
The 74AVC2T45-Q100 is a dual-bit, dual-supply transceiver that enables bidirectional
level translation. It features two data input-output ports (nA and nB), a direction control
input (DIR) and dual supply pins (V
CC(A)
and V
CC(B)
). Both V
CC(A)
and V
CC(B)
can be
supplied with any voltage between 0.8 V and 3.6 V. This flexibility makes 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 nA and DIR are referenced to V
CC(A)
and pins nB are referenced to
V
CC(B)
. A HIGH on DIR allows transmission from nA to nB and a LOW on DIR allows
transmission from nB to nA.
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 A and B 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.
