Overview
The SN74ALVC164245DGGT is a 16-bit (dual-octal) noninverting bus transceiver produced by Texas Instruments. This component is designed for asynchronous communication between data buses and features two separate supply rails. The A port operates at 2.5 V and 3.3 V, while the B port operates at 3.3 V and 5 V, allowing for voltage level translation between these environments. The control circuitry is powered by VCCA, ensuring efficient and reliable data transmission.
