**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 VCCA and VCCB. Both VCCA and VCCB 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 VCCA and pin B is referenced to VCCB. A HIGH on DIR allows transmission from A to B and a LOW on DIR allows transmission from B to A.
