74LVC1T45 Datasheet PDF - NXP

●General description

●The 74LVC1T45; 74LVCH1T45 are single bit, dual supply transceivers with 3-state outputs that enables bidirectional level translation. They feature one data input-output port (A and B), a direction control input (DIR) and dual supply pins (VCC(A) and VCC(B)). Both VCC(A) and VCC(B) can be supplied at any voltage between 1.2 V and 5.5 V making the device suitable for translating between any of the low voltage nodes (1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V and 5.0 V). Pins A and DIR are referenced to VCC(A) and pin B is referenced to VCC(B). A HIGH on DIR allows transmission from A to B and a LOW on DIR allows transmission from B to A.
