74AVC1T45-Q100
Dual-supply voltage level translator/transceiver; 3-state
Rev. 3 — 6 January 2016
Product data sheet
1. General description
The 74AVC1T45-Q100 is a single bit, dual supply transceiver with 3-state output that
enables bidirectional level translation. It features two 1-bit input-output ports (A and B), 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 at any voltage between 0.8 V and 3.6 V. This feature 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 A and DIR are referenced to V
CC(A)
and pin B is referenced
to V
CC(B)
. A HIGH on DIR allows transmission from A to B and a LOW on DIR allows
transmission from B to A.
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.
