SN74LVCH8T245RHLR TI 8-Bit Bus Transceiver | 24-VQFN (5.5x3.5) | 1.65-5.5V, 500Mbps

Product Overview

The SN74LVCH8T245RHLR is a high-performance 8-bit bus transceiver from Texas Instruments, designed for bidirectional voltage-level translation and data communication between different voltage domains. Housed in a compact 24-VQFN (5.5x3.5) package, this device supports a wide supply voltage range from 1.65V to 5.5V on both A and B ports, making it ideal for mixed-voltage systems. With a data rate of up to 500 Mbps, it ensures high-speed signal integrity while maintaining low power consumption. The device features dual-supply rails (VCCA and VCCB) that can be set independently, allowing seamless translation between 1.8V, 2.5V, 3.3V, and 5V logic levels. The SN74LVCH8T245RHLR is part of TI's LVC family, offering robust ESD protection and partial power-down (Ioff) capability to prevent backflow current when the device is powered down.
