www.ti.com SNLS171G – JANUARY 2005 – REVISED APRIL 2013 SCANSTA476 Eight Input IEEE 1149.1 Analog Voltage Monitor
Check for Samples: SCANSTA476 FEATURES DESCRIPTION The SCANSTA476 is a low power, Analog Voltage
Monitor used for sampling or monitoring up to 8
analog/mixed-signal input channels. Analog Voltage
Monitors are valuable during product development,
environmental test, production, and field service for
verifying and monitoring power supply and reference
voltages. In a supervisory role, the 'STA476 is useful
for card or system-level health monitoring and
prognostics applications. 1 2 Eight Selectable Analog Input Channels
