SCANSTA476TSD/NOPB

Supervisors Overview

The SCANSTA476TSD/NOPB is an analog voltage monitor designed for IEEE 1149.1 boundary scan applications. It features eight independent input channels capable of monitoring voltages within a 0 V to 5.5 V range. The device operates on a supply voltage between 2.7 V and 5.5 V, drawing a typical operating current of 5 mA and a maximum input current of 300 µA. It supports output currents up to 85 mA and functions reliably across a temperature range of -40°C to +85°C. Packaged in a WSON-16 surface-mount format, it integrates directly into JTAG-compliant test structures.

Supervisors Feature Summary

• Provides dedicated monitoring for eight distinct analog voltage inputs
• Complies with IEEE 1149.1 standards for boundary scan integration
• Supports standard supply voltage ranges compatible with common logic levels

Supervisors Applications

• IEEE 1149.1 (JTAG) boundary scan test environments
• System-level power supply voltage verification
• Embedded hardware diagnostic and monitoring circuits

Supervisors Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor assets are managed by Texas Instruments. Confirm that the specific suffix matches the required package and compliance specifications. Ensure compatibility with existing IEEE 1149.1 test architectures before finalizing procurement orders.

Supervisors Selection Notes

Select this component when eight-channel analog voltage monitoring is required within a JTAG-compatible framework. It is suitable for designs needing direct integration with boundary scan logic without additional external multiplexing. Consider the WSON-16 footprint and thermal characteristics during PCB layout planning.
