DUAL BIT DUAL POWER SUPPLY TRANSLATING

TRANSCEIVER WITH 3 STATE OUTPUTS

Description

Pin Assignments

The 74LVC2T45 is a dual-bit, dual-supply transceiver with tri-state

outputs suitable for transmitting two logic bits across different

voltage domains. The direction pin (DIR) and Port A, consisting of

pins 1A and 2A, have logic levels in relation to V_CC(A) while port B,

consisting of pins 1B and 2B have logic levels related to V_CC(B).

This arrange- ment allows for universal low-voltage translation

between any voltages from 1.2V to 5.5V. When a HIGH logic level

is applied to the direction pin, port A pins become inputs and port B

pins are outputs. Conversely, the roles of the ports are reversed

when the direction pin is asserted LOW.

V^CC

The tri-state (Ioff) feature places all port pins in a high impedance

state when either power supply is 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

either of the ports.
