产品概览
The SN74AVC4T774RSVR from Texas Instruments is a 4-bit dual-supply bus transceiver with configurable voltage-level shifting and 3-state outputs, housed in a UQFN-16 (RSV) package. It provides independent direction control per channel, supports data rates up to 380 Mbps, and operates across 1.1V to 3.6V dual rails, making it ideal for SPI, UART, and JTAG level translation.
