Description
General part information
74AXCH8T245 Series
The SN74AXCH8T245 device is an 8-bit non-inverting bus transceiver that resolves voltage level mismatch between devices operating at the latest voltage nodes (0.7 V, 0.8 V, and 0.9 V) and devices operating at industry standard voltage nodes (1.8 V, 2.5 V, 3.3 V) and vice versa.
The device operates by using two independent power-supply rails (VCCAand VCCB) . Data pins A1 through A8 are designed to track VCCA, which accepts any supply voltage from 0.65 V to 3.6 V. Data pins B1 through B8 are designed to track VCCB, which accepts any supply voltage from 0.65 V to 3.6 V. Additionally the SN74AXCH8T245 is compatible with a single-supply system.
The SN74AXCH8T245 device is designed for asynchronous communication between data buses. The device transmits data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level of the direction-control inputs (DIR1 and DIR2). The output-enable (OE) input is used to disable the outputs so the buses are effectively isolated.
