74AVC2T45DC-Q100H Product Information

General Description

The 74AVC2T45DC-Q100H is a dual-bit, dual-supply transceiver that enables bidirectional level translation. It has 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 nA to nB, and a LOW on DIR allows transmission from nB to nA. This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications.
