HS-26CT31EH_HS-26CT31RH Functional Diagram
Description
The Intersil HS-26CT31RH, HS-26CT31EH are quad differential line drivers designed for digital data transmission over balanced lines and meet the requirements of EIA standard RS-422. Radiation hardened CMOS processing assures low power consumption, High-Speed, and reliable operation in the most severe radiation environments. The HS-26CT31RH, HS-26CT31EH accept TTL signal levels and convert them to RS-422 compatible outputs. These circuits use special outputs that enable the drivers to power down without loading down the bus. Enable and disable pins allow several devices to be connected to the same data source and addressed independently. Specifications Specifications for Rad Hard QML devices are controlled by the Defense Logistics Agency Land and Maritime (DLA). The SMD numbers listed here must be used when ordering. Detailed Electrical Specifications for these devices are contained in SMD 5962-95632.

- Application NotePDF 301 KB an9519 Jan 10, 2002AI-generated Summary: The HS-26C(T)31RH radiation-hardened RS-422 line driver uses source termination resistors to match transmission line impedance, minimizing current and EMI. It features a BiCMOS output stage for power-off isolation and high drive capability, supporting cross-strapping in space systems. The device offers constant output impedance, high output current, and excellent radiation tolerance up to 300k RAD. It reduces power dissipation compared to CMOS and bipolar types while maintaining strong signal integrity and noise immunity.
- Application NotePDF 338 KB an9867 Nov 10, 1999AI-generated Summary: Electrical parameters are monitored during life testing to detect drift and failures, defined by exceeding datasheet limits. New products require less than 1% failure during burn-in, with failure analysis and corrective actions if exceeded. Sampling plans ensure defect rates below 3%. Life tests last 1000-3000 hours at 125°C depending on process maturity. Failure mechanisms include electromigration, ionic contamination, hot carrier injection, and dielectric rupture. Product sign-off requires all parties' approval after reliability confirmation. Space products undergo burn-in and quality conformance inspections with strict failure limits. Derating is unnecessary as datasheet limits are set at 6-sigma from characterization data, ensuring reliability.
- Application NotePDF 224 KB an9654 May 05, 1999AI-generated Summary: The document explains the reliability and failure mechanisms of semiconductor parts, focusing on life testing and wearout. It discusses how switching states cause transient current pulses and hot carrier injection, which only occur briefly during switching. Life testing at elevated temperatures accelerates aging to remove infant mortality failures, improving reliability. The failure rate follows a bathtub curve with infant mortality, useful life, and wearout phases, modeled by lognormal and exponential distributions. The Arrhenius equation relates failure rates at different temperatures. Burn-in and life tests reduce early failures without harming intrinsic reliability.
