SINGLE BIT DUAL POWER SUPPLY TRANSLATING

TRANSCEIVER WITH 3 STATE OUTPUTS

Description

Pin Assignments

The 74AVC1T45 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 V_CCA

while the B input/output tracks V_CCB. This arrangement allows for

universal low-voltage translation between any voltages from 1.2V to

3.6V. The Direction pin (DIR) controls the direction of the transceiver

and in a logic voltage related to V_CCA. 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

preventing damaging backflow currents and providing power down

electrical isolation up to 3.6 V as not to interfere with any logic activity

on pin A or B.
