General description
The 74AVCH2T45 is a dual bit, dual supply transceiver that enables bidirectional level translation.
It features two data 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 0.
8 V and 3.
6 V making the device suitable for translating between any of the low
voltage nodes (0.
8 V, 1.
2 V, 1.
5 V, 1.
8 V, 2.
5 V and 3.
3 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...
