SCANSTA111SMX/NOPB

Specialized Overview

The SCANSTA111SMX/NOPB is an enhanced scan bridge multidrop addressable interface component manufactured by Texas Instruments. It supports the IEEE 1149.1 (JTAG) boundary scan protocol for system-level testing and debugging. The device operates within a supply voltage range of 3 V to 3.6 V, with a maximum rating of 3.6 V and a minimum of 3 V. Typical operating supply current is 1.65 mA. It functions reliably across an industrial temperature range from -40°C to +85°C. The component is housed in a 49-pin NFBGA package suitable for surface mount technology (SMD/SMT). It carries RoHS compliance details and exhibits moisture sensitivity.
