Description
AI
The 74LVC2T45; 74LVCH2T45 are dual bit, dual supply translating transceivers with 3-state outputs that enable bidirectional level translation. They feature two 2-bits input-output ports (nA and nB), 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 nA and DIR are referenced to VCC(A)and pins nB are referenced to VCC(B). A HIGH on DIR allows transmission from nA to nB and a LOW on DIR allows transmission from nB to nA.
