74AVC1T45
Rev. 7 — 24 August 2017
Dual-supply voltage level translator/transceiver; 3-state
Product data sheet
1
General description
The 74AVC1T45 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 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 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.
