74AVC1T45 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 (Top View) 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 . This arrangement allows for Vcc(A) 1 6 CCB Vcc(B) universal low-voltage translation between any voltages from 1.2V to GND 2 5 DIR 3.6V. The Direction pin (DIR) controls the direction of the transceiver ( ) Top View and in a logic voltage related to V . When a high logic level is CCA 3 4 A B Vcc(A) Vcc(B) 1 6 applied to DIR the A pin becomes an input and the B pin becomes the SOT26 output. Conversely the roles of A and B are reversed when DIR is GND 2 5 DIR SOT363 asserted low. A 3 4 B ( Bottom View) The tri-state feature occurs when either of the power supply voltages X1-DFN1010-6 are zero. This is also an Ioff feature and allows for the output to A 3 4 B X2-DFN0910-6 remain in a high-impedance state with both power supplies at 0V X2-DFN1410-6 GND 2 5 DIR preventing damaging backflow currents and providing power down electrical isolation up to 3.6 V as not to interfere with any logic activity Vcc(A) 1 6 Vcc(B) on pin A or B.
