Overview
The LMH7324SQX/NOPB is a quad high-speed comparator manufactured by Texas Instruments. It features RSPECL outputs and operates within a supply voltage range of 2.7V to 12V (single) or ±1.35V to ±6V (dual). The device exhibits a maximum propagation delay of 0.783ns and includes 75mV of hysteresis. Input offset voltage is typically 8mV at 5V, with a maximum input bias current of 5µA at 5V. Static current consumption is limited to 10mA maximum. It functions in temperatures from -40°C to +125°C and utilizes a 24-WQFN package.
Feature Summary
- Integrates four independent high-speed comparators in a single compact package.
- Provides RSPECL output drivers for high-speed digital signaling compatibility.
- Incorporates internal hysteresis to improve noise immunity during signal transitions.
- Supports flexible power supply configurations for single or dual rail operation.
Applications
- High-speed data acquisition systems requiring fast threshold detection.
- Video signal processing circuits utilizing differential signaling standards.
- Precision timing and pulse generation applications.
- Communication interfaces demanding low propagation delay characteristics.
Procurement Notes
Verify the specific suffix 'SQX' against the manufacturer's official documentation to confirm the exact tape-and-reel packaging configuration and temperature grade. Ensure the ordering part number matches the required WQFN-24 footprint and pinout specifications for your PCB layout. Cross-reference the datasheet revision date to validate all electrical parameters before finalizing procurement contracts.
Selection Notes
Select this component when multiple independent comparison channels are required within a constrained board area. The RSPECL output interface is suitable for systems interfacing with LVDS-compatible receivers. Consider the 10mA maximum static current limit for power-sensitive designs. Verify that the 2.7V minimum supply voltage aligns with the system's available power rails.
Part Context
This device belongs to the LMH732x family of high-speed comparators from Texas Instruments. It serves as the quad-channel counterpart to the dual-channel LMH7322. The series is designed for applications requiring sub-nanosecond response times and differential output capabilities. The SQX variant denotes the specific surface-mount packaging and reel quantity offered by the manufacturer.
Replacement Considerations
The LMH7322SQ/NOPB is a verified two-channel alternative within the same family. Verify pin compatibility and channel count requirements before substitution. Other members of the LMH732x series may offer similar performance but differ in channel density.
