Texas Instruments SN74AXCH8T245/SN74AXCH8T245-Q1 Bus Transceiver
Texas Instruments SN74AXCH8T245/SN74AXCH8T245-Q1 Dual-Supply Bus Transceiver is an 8-bit non-inverting bus transceiver that resolves voltage level mismatch between devices operating at the latest voltage nodes. These nodes include devices operating at 0.7V, 0.8V, and 0.9V and devices operating at industry standard voltage nodes (1.8V, 2.5V, 3.3V) and vice versa.
The Texas Instruments SN74AXCH8T245/SN74AXCH8T245-Q1 Bus Transceiver is offered in TSSOP-24 and VQFN-24 packages. The Q1 variant is AEC-Q100 qualified for automotive applications.
