Overview
LM119H/883 from Texas Instruments is a radiation-hardened, high-speed dual comparator in TO-100 metal can package (10-pin), operating from ±15V or single 5V supply, with 80 ns typical response time, 10.5 kV/V voltage gain, and input offset voltage ≤±3.8 mV at 25°C. It drives TTL/DTL/RTL loads and relays up to 25 mA, used in precision analog monitoring and fault-detection circuits in aerospace power systems.
For engineers reviewing the LM119H/883 datasheet, LM119H/883 pinout, LM119H/883 application, or LM119H/883 equivalent, this page delivers verified military-grade comparator specifications, radiation tolerance data (100 krad(Si) high dose rate & ELDRS-free), thermal derating guidance, and validated alternatives for space-qualified analog signal conditioning designs.
Technical Context
The LM119H/883 implements two independent open-collector comparators with uncommitted outputs, enabling wired-OR logic and direct interface to lamps, relays, and digital logic families. Its input stage supports common-mode voltages from −12 V to +12 V under ±15 V supplies, and features high slew rate and CMRR ≥80 dB.
Designed for MIL-STD-883 Class B screening, it undergoes full temperature testing (−55°C to +125°C), dynamic switching characterization, and post-radiation validation per SMD 5962-9679801/02. Input bias current remains ≤0.95 µA across temperature, and output saturation voltage is ≤1.5 V at 25 mA sink current.

FAQ
What is the maximum operating temperature range for LM119H/883?
The LM119H/883 is fully specified and tested from −55°C to +125°C per MIL-STD-883 Method 1010. This extended range is validated across all electrical parameters including input offset voltage, response time, and output saturation voltage - ensuring reliable operation in jet engine bays and orbital thermal cycles. The TO-100 package's metal can construction contributes to thermal robustness.
Does LM119H/883 support single-supply operation?
Yes, LM119H/883 operates from a single +5 V supply with ground reference, as confirmed in the TI SNOSAN3B datasheet Section 1 "Features" and Electrical Characteristics tables. Input common-mode range extends to 1.0 V–3.0 V under this condition, and output saturation voltage is ≤0.4 V at 4 mA load - enabling direct interface to 5 V logic without level shifters.
What radiation qualifications does LM119H/883 meet?
LM119H/883 meets two distinct radiation standards: High Dose Rate (HDR) qualification to 100 krad(Si) per SMD 5962-9679801, and ELDRS-Free qualification to 100 krad(Si) per SMD 5962-9679802. Both are verified via MIL-STD-883 Method 1019 testing, with pre- and post-radiation parameter limits identical except where explicitly noted in delta tables.
Can LM119H/883 drive a mechanical relay directly?
Yes, LM119H/883 can directly drive a mechanical relay coil: its open-collector output sinks up to 25 mA at ≤1.5 V saturation voltage under ±15 V supplies, matching typical 5 V/12 V relay coil requirements. A flyback diode must be placed across the coil, and the pull-up resistor should be selected to limit power dissipation while ensuring clean logic transitions.
What is the pin 5 connection on LM119H/883?
Pin 5 on LM119H/883 is V− (negative supply terminal) and is internally connected to the metal case of the TO-100 package. This requires careful PCB layout: the case must be tied to the most negative system potential, and the V− trace must provide a low-inductance return path to avoid oscillation or false triggering during fast transients.
