74AVC20T245-Q100 20-bit dual supply translating transceiver with configurable voltage translation 3-state Rev. 2 14 January 2019 Product data sheet 1. General description The 74AVC20T245-Q100 is a 20-bit, dual supply transceiver that enables bi-directional voltage level translation. The device can be used as two 10-bit transceivers or as a single 20-bit transceiver. It features four 10-bit input-output ports (1An, 1Bn and 2An, 2Bn), two output enable inputs (nOE), two direction inputs (nDIR) and dual supplies (V and V ). V and V CC(A) CC(B) CC(A) CC(B) can be independently supplied at any voltage between 0.8 V and 3.6 V making the device suitable for bi-directional voltage level translation 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. The 1An and 2An ports, nOE and nDIR are referenced to V , the 1Bn CC(A) and 2Bn ports are referenced to V . A HIGH on a 1DIR allows transmission from 1An to 1Bn CC(B) and a LOW on 1DIR allows transmission from 1Bn to 1An. A HIGH on nOE causes the outputs to assume a HIGH impedance OFF-state. The device is fully specified for partial power-down applications using I . The I circuitry OFF OFF disables the output, preventing any damaging backflow current through the device when it is powered down. In suspend mode when either V or V are at GND level, all output ports will CC(A) CC(B) assume a high impedance OFF-state. This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications. 2.
