LM211DG

LM211DG is a high-speed, single‑channel voltage comparator from the LM211 family (National/TI). It compares two input voltages and outputs a digital‑type signal.
Key points
- Output: open‑collector (requires a pull‑up resistor; allows wired‑OR configurations).
- Speed: fast propagation delay (tPD in the tens to hundreds of nanoseconds range, depending on supply and conditions).
- Supply: designed for single or dual supplies over a wide range (check exact datasheet for values).
- Input: differential inputs with common‑mode range that includes the negative rail; suitable for single‑supply operation.
- Hysteresis: can be implemented with positive feedback to improve noise immunity.
- Packaging: DG suffix denotes a specific package/grade variant (typically 8‑pin package such as DIP/SOIC) and temperature rating.
Applications
- Zero‑crossing detection, level shifting, PWM comparators, threshold/window detectors, and simple fast decision circuits.
Notes
- Always consult the LM211DG datasheet for exact electrical specs, pinout, and recommended operating conditions for your chosen package and temperature range.

LM211DG is a high‑speed voltage comparator with an open‑collector output. Key features:
- Open‑collector output (sinks current; requires pull‑up resistor)
- High‑speed voltage comparison suitable for fast timing tasks
- Wide supply range (single or dual supply)
- Input common‑mode range includes the negative rail (ground)
- Outputs compatible with TTL/CMOS levels via pull-up
- Industrial temperature range (typical: -40°C to 85°C)
- 8-pin package (DG suffix indicates a small-outline/DIP‑8 style)
Note: For exact voltage, current, and timing specs, consult the datasheet.

LM211DG is an 8-pin DIP (DIP-8) package, through-hole, Pb-free (green).

- Pin count: 8 pins (8-pin package)
- Function: High-speed voltage comparator (single-channel) with open-collector output (requires a pull-up resistor). It compares two analog input voltages and provides a digital output indicating which input is higher.

The LM211DG is manufactured by Texas Instruments (TI). TI is an American multinational semiconductor company that designs and manufactures a wide range of analog and digital integrated circuits, sensors, and embedded processing solutions. It is one of the largest semiconductor companies in the world.
