Product details
Overview
JL111BGA from Texas Instruments is a precision voltage comparator in an 8-pin TO-99 metal can package, featuring 200 nA max input current, ±30 V differential input voltage range, and compatibility with TTL/DTL/RTL logic families. It operates from single 5V to dual ±15V supplies and drives loads up to 50 mA at 50 V, supporting relay control and zero-crossing detection in aerospace-grade analog signal conditioning.
For engineers reviewing the JL111BGA datasheet, JL111BGA pinout, JL111BGA application, or JL111BGA equivalent, this page delivers verified electrical parameters, military-grade operating temperature range (−55°C to +125°C), strobe-enabled output disable, offset null capability, and confirmed TO-99 (LMC0008C) package mapping - all critical for high-reliability comparator selection in avionics and industrial control systems.
Technical Context
The JL111BGA implements an open-collector NPN output stage with independent strobe control (Pin 7), enabling full output disable without affecting input bias or common-mode behavior. Its input stage uses matched transistor pairs to achieve 20 nA max offset current and 3 mV max input offset voltage over temperature.
It supports isolated ground referencing: inputs and outputs operate independently of system ground, allowing load switching referenced to V+, V−, or GND. The device includes dedicated offset null pins (5 and 6) and exhibits 300 ns typical response time with 5 mV overdrive into 50 pF load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Current | 200 nA max over full −55°C to +125°C range - enables high-impedance sensor interfacing without loading source |
| Offset Voltage | ±3.0 mV max at 25°C - ensures accurate threshold detection in precision level-shifting circuits |
| Differential Input Range | ±30 V - allows direct comparison of signals across wide voltage domains, e.g., motor phase voltages |
| Output Sink Current | 50 mA continuous - drives relays, lamps, or logic gates without external buffer transistors |
| Supply Voltage Range | Single 5V to dual ±15V - interoperates with both digital logic rails and legacy op amp supplies |
| Response Time | 300 ns typical with 5 mV overdrive - supports fast edge detection in pulse-width modulation feedback loops |
| Strobe Function | Pin 7 accepts up to 10 mA sink current to disable output - provides synchronized blanking in multiplexed measurement systems |
| Operating Temperature | −55°C to +125°C - qualified per MIL-STD-883 Group A subgroups for extended life in harsh environments |
Pinout & Package
Package: TO-99 metal can (package number LMC0008C), hermetically sealed, 8-pin circular layout with case connected to Pin 4 (V−). Height ≤5.72 mm, lead diameter ≤1.397 mm, RoHS-exempt construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output Collector | Open-collector NPN output - requires external pull-up; sinks up to 50 mA when active |
| 2 | Inverting Input (−) | Differential input node - referenced to internal matched pair; supports ±30 V common-mode range |
| 3 | Non-Inverting Input (+) | Differential input node - identical CMR and bias specs as Pin 2; used for threshold or reference input |
| 4 | Case / V− | Metal case internally tied to negative supply - must be connected to system V− or ground per layout guidelines |
| 5 | Offset Null (−) | Connects to emitter of input stage PNP - used with Pin 6 to trim input offset voltage to <1 mV |
| 6 | Offset Null (+) | Connects to base of input stage PNP - forms adjustable voltage divider with Pin 5 for VIO nulling |
| 7 | Strobe Input | Sink input: pulling ≥1 mA disables output stage - enables time-gated comparisons without power cycling |
| 8 | V+ | Positive supply terminal - accepts up to +30 V; total supply voltage limited to 36 V across V+ and V− |
Key Features
| Feature | Design Value |
|---|---|
| Input isolation from ground | Both inputs float independently of system ground - enables high-side sensing in battery management systems |
| Output load referencing | Output drives loads tied to V+, GND, or V− - eliminates need for level-shifting circuitry in multi-rail systems |
| Strobe-controlled output disable | Pin 7 sink current disables collector output while preserving input bias and offset stability - critical for time-sliced ADC triggering |
| Offset voltage nulling | Pins 5 and 6 support <1 mV residual offset after trimming - improves accuracy in precision window comparators |
| Wide supply flexibility | Operates from single 5V logic rail up to ±15V op amp supplies - simplifies mixed-signal board power architecture |
| Military-grade thermal performance | θJA = 150°C/W (still air) in TO-99 package - sustains full 50 mA output current at +125°C ambient with proper heatsinking |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM111H | Same die, TO-99 package with different marking and screening; no MIL-STD-883 Group A testing documented | Lacks full military conformance testing (e.g., subgroup 8B dynamic tests at −55°C) | Select LM111H only for commercial-temperature non-critical signal routing where cost is primary constraint |
| LM311DR | SOIC-8 surface-mount package; 250 nA input current; 200 ns typical response; no strobe pin | Cannot perform synchronized output blanking; unsuitable for time-gated measurement architectures | Choose LM311DR for automated assembly and space-constrained PCBs where strobe functionality is not required |
Compared with LM111H and LM311DR, JL111BGA uniquely combines hermetic TO-99 packaging, MIL-STD-883 Group A qualification, strobe-enabled output disable, and −55°C to +125°C guaranteed operation - making it irreplaceable in radiation-tolerant and thermally extreme avionics monitoring systems.

FAQ
What is the maximum allowable differential input voltage for JL111BGA?
The JL111BGA supports a differential input voltage range of ±30 V, as specified in its Absolute Maximum Ratings table. This rating applies regardless of supply configuration - whether operated from single 5V, dual ±15V, or asymmetric rails such as +29.5V/−0.5V. Exceeding ±30 V risks permanent damage to the input stage. The JL111BGA maintains this rating across its full −55°C to +125°C operating temperature range.
Does JL111BGA support output wire-OR'ing, and how is it implemented?
Yes, JL111BGA supports output wire-OR'ing via its open-collector NPN output (Pin 1). Multiple JL111BGA outputs can share a common pull-up resistor to V+ or another rail, producing a logical AND function at the node. This is explicitly confirmed in the datasheet's "DESCRIPTION" section and used in applications like fault-bus signaling. No additional external components are required beyond the shared pull-up.
How is the strobe function of JL111BGA electrically configured?
The JL111BGA strobe input (Pin 7) is a current-sink terminal rated for up to 10 mA. Pulling ≥1 mA from Pin 7 through an external resistor to V+ disables the output transistor, forcing Pin 1 into high-impedance state. The strobe does not affect input bias or offset voltage - it only gates the output stage. Datasheet Figure 24 confirms this behavior with a typical 10 kΩ pull-up to V+ and 10 mA sink limit.
What package type and mechanical dimensions define JL111BGA?
JL111BGA uses the TO-99 metal can package designated LMC0008C: 8-pin circular layout, hermetically sealed, with case connected to Pin 4 (V−). Key dimensions include 5.72 mm maximum height, 8.51 mm maximum diameter, and 1.397 mm maximum lead diameter. The package outline drawing (TI document 4220610/B) and JEDEC MO-002 registration confirm full mechanical compatibility with standard TO-99 sockets.
Is JL111BGA pin-compatible with LM106 or LM710 comparators?
Yes, JL111BGA shares identical pin configuration with LM106 and LM710 as stated in the datasheet: "The LM111 has the same pin configuration as the LM106 and LM710." All three devices use Pin 1 for output, Pin 2 for inverting input, Pin 3 for non-inverting input, Pin 4 for V−/case, Pins 5–6 for offset null, Pin 7 for strobe (LM111-specific), and Pin 8 for V+. However, JL111BGA adds strobe functionality absent in LM106/LM710, so Pin 7 must be properly terminated in legacy designs.
