HS-26C31RH
Data Sheet
August 1999
File Number 3401.3
Radiation Hardened Quad Differential Line
Driver
Features
• Electrically Screened to SMD # 5962-96663
The Intersil HS-26C31RH 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.
• QML Qualified per MIL-PRF-38535 Requirements
• 1.2 Micron Radiation Hardened CMOS
- Total Dose Up to . . . . . . . . . . . . . . . . . . . . 300kRAD(Si)
9
- Dose Rate Upset . . . . . . . > 1x10 RAD/s (20ns Pulse)
• Latchup Free
The HS-26C31RH accepts CMOS signal levels 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.
• EIA RS-422 Compatible Outputs (Except for IOS)
• CMOS Inputs
• High Impedance Outputs when Disabled or Powered
Down
• Low Power Dissipation . . . . . . . . . 2.75mW Standby (Max)
• Single 5V Supply
Specifications for Rad Hard QML devices are controlled
by the Defense Supply Center in Columbus (DSCC). The
SMD numbers listed here must be used when ordering.
• Low Output Impedance . . . . . . . . . . . . . . . . . 10Ω or Less
