SINGLE BIT DUAL POWER SUPPLY TRANSLATING
TRANSCEIVER WITH 3 STATE OUTPUTS
Description
Pin Assignments
The 74LVC1T45 is a single bit, dual supply transceiver with 3-state
(Top View)
outputs suitable for transmitting a single logic bit across different
voltage domains. The A input/output pin is designed to track VCCA
Vcc(A) 1
while the B input/output tracks VCCB. This arrangement allows for
universal low-voltage translation between any voltages from 1.65V to
GND 2
5.5V. The Direction pin (DIR) controls the direction of the transceiver
and in a logic voltage related to VCCA. When a high logic level is
A 3
applied to DIR the A pin becomes an input and the B pin becomes the

output. Conversely, the roles of A and B are reversed when DIR is

asserted low.
(Bottom View)
The 3-state feature occurs when either of the power supply voltages
A 3
are zero. This is also an Ioff feature and allows for the output to
remain in a high impedance state with both power supplies at 0V,

preventing and damaging backflow currents and providing power
Vcc(A) 1
down electrical isolation up to 5.5V as not to interfere with any logic
activity on pin A or B.
