Product Overview
The DS26LS31MJ/883 is military-grade quad differential line driver from TI (originally National Semiconductor), designed for aerospace and defense high-reliability communication. It meets RS-422/RS-423 standards, with four independent drivers converting TTL/CMOS signals to differential outputs. Rated -55°C to +125°C, screened per MIL-STD-883 Class B. Tri-state outputs support multi-drop bus layout, hermetic CDIP-16 package resists harsh temperature and humidity for mission-critical equipment.
Core Advantages
MIL-STD-883 Class B Qualified
Pass full military environmental screening and burn-in test, stable for defense & aerospace systems.
Strong Differential Drive Capability
Maintain stable signal integrity over long twisted pair cables, fit for terminated transmission lines.
Minimal Channel Skew
Ultra-low inter-channel delay skew under 2ns, avoid data error in synchronous high-speed circuits.
Hermetic Ceramic CDIP-16 Package
Sealed ceramic packaging isolates moisture and vibration, far more reliable than plastic DIP in extreme environments.

Frequently Asked Questions
Q1: What’s the difference between DS26LS31MJ/883 and commercial DS26LS31N?
A1: The military version passes MIL-STD-883 Class B screening, adopts hermetic ceramic CDIP packaging, working temp -55℃~125℃. Commercial model uses plastic DIP, only 0℃~70℃ without military reliability test.
Q2: Is DS26LS31MJ/883 RoHS compliant?
A2: Not standard RoHS compliant. It uses leaded pins to prevent tin whiskers, exempt for military & aerospace projects.
Q3: Why tri-state outputs suit multi-drop bus circuit?
A3: Tri-state high-impedance disconnects driver from differential bus when disabled, allowing multiple drivers to share one bus without signal conflict.
Q4: Which resistor matches RS422 long cable transmission?
A4: 120Ω termination resistor at cable end matches twisted pair impedance and eliminates signal reflection.
Q5: Can this chip be used for deep space projects?
A5: It meets MIL-STD-883 Class B for general aerospace; extra anti-radiation screening is required for deep space use.
Q6: Are CDIP-16 sockets available for this component?
A6: Yes, standard 16-pin through-hole ceramic DIP sockets support easy replacement in military test equipment.
Q7: What is the supply voltage range of DS26LS31MJ/883?
A7: Operating supply voltage ranges from 4.5V to 5.5V, nominal 5V.
Q8: Do you provide free samples of DS26LS31MJ/883?
A8: Small samples are available for testing; you can send sample requests, we reply within 24 hours.
Q9: What is your bulk order lead time for this military IC?
A9: Small bulk stock ships in 2-3 working days; large quantity orders take 4-6 weeks depending on demand.
Q10: Can I replace DS26LS31MJ/883 with other RS422 drivers?
A10: Commercial plastic RS422 drivers cannot replace it for military equipment due to temperature and screening standards.
Q11: Does this chip support RS423 communication protocol?
A11: Yes, it fully complies with RS-422 and RS-423 industry standards.
