SCANSTA111MT/NOPB TI IEEE 1149.1 JTAG Bus | 48-TSSOP | 2.7V-3.6V, 50MHz

Product Overview

The SCANSTA111MT/NOPB from Texas Instruments is a high-performance IEEE 1149.1 (JTAG) bus switch designed for test and debug applications. It enables multiplexing of multiple JTAG chains into a single test access port (TAP), simplifying board-level testing and reducing test time. Housed in a 48-pin TSSOP package, this device operates over a wide voltage range of 2.7V to 3.6V and supports clock frequencies up to 50MHz. The SCANSTA111MT/NOPB is RoHS compliant and lead-free (NOPB), making it suitable for environmentally conscious designs.
