74LVC1T45 SINGLE BIT DUAL POWER SUPPLY TRANSLATING TRANSCEIVER WITH 3 STATE OUTPUTS Description Pin Assignments The 74LVC1T45 is a single-bit, dual-supply transceiver with tri-state outputs suitable for transmitting a single logic bit across different (Top View) (Top View) voltage domains. The A input/output pin is designed to track VCCA Vcc(A) 1 6 Vcc(B) while the B input/output tracks VCCB. This arrangement allows for Vcc(A)1 6 Vcc(B) universal low-voltage translation between any voltages from 1.65V to GND 2 5 DIR GND 2 5 DIR 5.5V. The Direction pin (DIR) controls the direction of the transceiver A 3 4 B and in a logic voltage related to VCCA. When a high logic level is A 3 4 B applied to DIR, the A pin becomes an input, and the B pin becomes X2-DFN1410-6 the output. Conversely, the roles of A and B are reversed when DIR is SOT26 SOT363 SOT563 asserted low. (Bottom View) The tri-state feature occurs when either of the power supply voltages (Top View) are zero. This is also an Ioff feature and allows for the output to A 3 4B Vcc(A) 1 6 Vcc(B) remain in a high impedance state with both power supplies at 0V, GND2 5DIR GND 2 5 DIR which prevents and damages backflow currents and provides power- A 3 4 B down electrical isolation up to 5.5V as not to interfere with any logic Vcc(A)1 6 Vcc(B) activity on pin A or B.
