Overview
The LM111JG is a single high-speed voltage comparator manufactured by Texas Instruments, housed in an 8-pin Ceramic Dual In-Line Package (CDIP). It operates within a supply voltage range of 3.5 V to 30 V and supports an operating temperature range from -55°C to +125°C. The device features a fast response time with a typical low-to-high output transition of 115 ns and a high-to-low transition of 165 ns. Electrical characteristics include a maximum input bias current of 300 nA and a maximum input offset current of 70 nA at full temperature range.
Feature Summary
- Features strobe capability for controlling the output state independently of differential inputs.
- Includes dedicated balance pins allowing for external offset adjustment or trimming.
- Provides open collector output compatible with TTL and MOS logic circuits.
- Capable of driving loads such as lamps or relays with high voltage and current switching.
Applications
- Desktop PCs
- Body Control Modules
- White Goods
- Building Automation
- Oscillators
Procurement Notes
Verify that the specific orderable part number matches the required package type and temperature rating. Confirm whether the component meets military specifications if applicable, as production processing does not necessarily include testing of all parameters unless explicitly stated for MIL-PRF-38535 compliant products. Ensure compatibility with system ground isolation requirements.
Selection Notes
Select the LM111JG when a wide supply voltage range and high-speed comparison are required alongside ceramic packaging for durability. Consider this device for applications needing offset balancing and strobe functionality. Verify that the open collector output configuration aligns with the downstream logic interface requirements.
Part Context
The LM111JG belongs to the LMx11 family of differential comparators, which includes the LM211 and LM311 variants. These devices share similar electrical architectures but differ in specified temperature ranges and automotive qualification status. The JG suffix specifically denotes the 8-pin CDIP package format.

FAQ
How does the strobe pin function?
When the strobe input is low, the output is forced into the off state regardless of the differential input voltage condition.
Can the outputs be wire-OR connected?
Yes, the open collector outputs can be wire-OR connected to drive multiple loads or logic inputs.
