General description
The 74AVCH4T245 is a 4-bit, dual supply transceiver that enables bidirectional level translation.
The device can be used as two 2-bit transceivers or as a 4-bit transceiver.
It features two 2-bit input-output ports (nAn and nBn), a direction control input (nDIR), a output enable input (nOE) 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 nAn, nOE and nDIR are referenced to VCC(A) and pins nBn are referenced to VCC(B).
A HIGH on nDIR allows transmission from nAn to nBn and a LOW on nDIR allows transmission from nBn to nAn.
The output enable input (nOE) can be used to disable the outputs so the buses are effectively...
