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 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 (Top View ) Vcc(A) 1 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 VCCA. When a high logic level is 6 Vcc(B) GND 2 5 DIR 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. 4 B SOT26 SOT363 (Top View ) Vcc(A) 1 GND 2 A (Bottom View) 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.
