74LVC1T45
SINGLE BIT DUAL POWER SUPPLY TRANSLATING
TRANSCEIVER WITH 3 STATE OUTPUTS
Description
The 74LVC1T45 is a single-bit, dual-supply transceiver with tri-
state
outputs suitable for transmitting a single logic bit across different
voltage domains. The A input/output pin is designed to track VCCA
while the B input/output tracks VCCB. This arrangement
allows for
universal low-voltage translation between any v
oltages from 1.65V to
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
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.
The tri-state feature occurs when either of the power supply voltages
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,
which prevents and damages backflow currents and provides power-
down electrical isolation up to 5.5V as not to interfere with any logic
activity on pin A or B.
