HS-26CT31RH-T Data Sheet July 1999 Radiation Hardened Quad Differential Line Driver File Number 4590.1 Features Intersil’s Satellite Applications Flow™ (SAF) devices are fully tested and guaranteed to 100kRAD total dose. These QML Class T devices are processed to a standard flow intended to meet the cost and shorter lead-time needs of large volume satellite manufacturers, while maintaining a high level of reliability. • QML Class T, Per MIL-PRF-38535 • Radiation Performance - Gamma Dose . . . . . . . . . . . . . . . . . . . . 1 x 105 RAD(Si) - SEU and SEL . . . . . . . . . . Immune to 100MeV/mg/cm2 • EIA RS-422 Compatible Outputs (Except for IOS) • TTL Compatible Inputs The Intersil HS-26CT31RH-T is a Quad Differential Line Driver designed for digital data transmission over balanced lines and meets 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. • High Impedance Outputs when Disabled or Powered Down The HS-26CT31RH-T accepts TTL inputs and converts them to RS-422 compatible outputs. This circuit uses 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. • Full -55oC to 125oC Military Temperature Range • Low Power Dissipation 2.75mW Standby (Max) • Single 5V Supply • Low Output Impedance 10Ω or Less Pinouts HS1-26CT31RH-T (SBDIP), CDIP2-T16 TOP VIEW Specifications AIN 1 16 VDD AO 2 15 DIN Specifications for Rad Hard QML devices are controlled by the Defense Supply Center in Columbus (DSCC).
