SCANSTA112VSX

Specialized Overview

The SCANSTA112VSX is a 7-port multidrop multiplexer designed for IEEE 1149.1 (JTAG) compliance, manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 3.6 V and supports 32-bit data paths with a propagation delay of 12 ns. The component is housed in a TQFP-100 surface-mount package and functions reliably across an industrial temperature range from -40°C to +85°C. This device facilitates efficient scan chain management in complex digital systems.
