Product Overview
The SN74LV8T596BQBR from Texas Instruments is a high-performance 8-bit shift register with output latches and 3-state outputs. It operates over a wide voltage range of 1.65V to 5.5V, making it suitable for interfacing with both 3.3V and 5V logic families. The device features a serial input (SER), a shift clock (SRCLK), a storage register clock (RCLK), and an output enable (OE). Data is shifted into the register on the rising edge of SRCLK and transferred to the storage register on the rising edge of RCLK. The 3-state outputs allow for bus-oriented applications. The device is available in a compact 16-WQFN (2.5x3.5mm) package, ideal for space-constrained designs.
