Vue d'ensemble

Description

Introduction to LM293MDREP
The LM293MDREP is TI’s dual voltage comparator in the MDREP package. It contains two independent comparators with open-collector outputs, suitable for fast, low-power voltage comparisons in single- or dual-supply systems.
Key points:
- Inputs: differential; common-mode range includes ground; supports single-supply operation over a wide Vcc range.
- Outputs: two open-collector stages; require pull-up resistors to a suitable logic or supply level; can sink but not source current.
- Supply: broad operating voltage (typical 2–36 V) with standard temperature ranges; low power consumption.
- Applications: level detection, zero-crossing/window detectors, battery monitoring, and general threshold sensing.
Packaging/ordering:
- MDREP denotes the specific package/reel option; consult the TI datasheet for exact pinout, mechanical dimensions, and RoHS details.
Note: For precise electrical specs (offset voltage, bias current, propagation delay) refer to the LM293 family datasheet.

Features

LM293MDREP features (typical):
- Dual general-purpose voltage comparators in one package
- Open-collector outputs on both channels (requires pull-up resistors)
- Input common-mode range includes ground; supports single-supply operation
- Wide supply voltage range (roughly 2 V to 36 V)
- Low-power operation
- Outputs can sink current; TTL/CMOS-compatible input thresholds through pull-ups
- Broad industrial temperature range (-40°C to +125°C)
- Package: MDREP (molded DIP-8) with Tape & Reel (reel-packaged)
Note: For exact electrical specs (offset, propagation delay, input bias, etc.), please consult the datasheet.

Package

The LM293MDREP comes in an 8-pin molded DIP (MD) package, shipped in tape-and-reel (REP) packaging.

Pinout

LM293MDREP is an 8‑pin device containing two independent voltage comparators with open-collector outputs. Pinout (8-pin package): 1 = Output 1, 2 = Inverting input 1, 3 = Non‑inverting input 1, 4 = GND, 5 = Non‑inverting input 2, 6 = Inverting input 2, 7 = Output 2, 8 = Vcc. Outputs require pull-up resistors.

Manufacturer

Texas Instruments. TI is a multinational semiconductor company that designs and manufactures analog and embedded processing integrated circuits.

Application

LM293MDREP is a dual voltage comparator with open-collector outputs. Typical applications include:
- Threshold/level-detection and level shifting
- Window detectors
- Battery/power-fail monitoring and supervisory circuits
- Zero-cross and AC mains sensing
- Sensor conditioning (thermistors, photoresistors)
- PWM/control-loop feedback for motor drives or power supplies
- Alarm and protection circuits (over/under-voltage)

Equivalent

LM293MDREP is a dual open-collector comparator, essentially equivalent to the LM393. Common substitutes: LM393/LM393N and LM2903 (and their vendor equivalents). Pinout in DIP8 is the same: 1=Out A, 2=In− A, 3=In+ A, 4=GND, 5=In+ B, 6=In− B, 7=Out B, 8=Vcc.
