ET74LVCH1T45

概要

The ET74LVCH1T45 is a dual-bit, dual-supply transceiver that enables bidirectional level translation. It features two data input-output ports (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 1.65V and 5.5V making the device suitable for translating between any of the low voltage nodes (1.2V, 1.5V, 1.8V, 2.5V, 3.3V and 5.0V). Pin A and DIR are referenced to VCC(A) and pin B are 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.
