74AVCH20T245 - 20-bit Dual Supply Translating Transceiver

General Description

The 74AVCH20T245 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.

Key Features

  • four 10-bit input-output ports (1An, 1Bn and 2An, 2Bn), two output enable inputs (nOE), two direction inputs (DIR) and dual supplies (VCC(A) and VCC(B)). VCC(A) and VCC(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 VCC(A), the 1Bn and 2Bn ports are referenced to VC.
