SN74AXCH8T245 Overview
The SN74AXCH8T245 device is an 8-bit noninverting 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 (VCCA and VCCB) . Data pins A1 through A8 are designed to track VCCA, which...
