SCANSTA476TSD/NOPB TI IEEE 1149.1 JTAG | 16-WSON (5X5) | 1.8V-5V, 8 TAP Ports

Product Overview

The SCANSTA476TSD/NOPB from Texas Instruments is a high-performance IEEE 1149.1 (JTAG) bus switch designed for multi-drop test access port (TAP) management. It enables seamless integration of multiple JTAG-compliant devices in a single scan chain, reducing test time and complexity. Housed in a compact 16-WSON (5x5 mm) package, this device supports a wide voltage range from 1.8V to 5V, making it suitable for mixed-voltage systems. With eight TAP ports, it provides flexible routing for boundary-scan testing in complex digital designs.
