Overview
The LMH7322SQX/NOPB is a dual high-speed comparator manufactured by Texas Instruments, housed in a 24-WQFN (4x4) package. It features RSPECL outputs and supports single or dual supply voltages ranging from 2.7V to 12V or ±1.35V to ±6V. Key electrical parameters include a maximum propagation delay of 0.783ns, typical CMRR and PSRR of 80dB, and a maximum input offset voltage of 8mV at 5V. The device operates within a temperature range of -40°C to 125°C, draws a maximum static current of 10mA, and provides a typical output current of 25mA with 75mV hysteresis.
Feature Summary
- Provides differential, LVDS, and RSPECL output configurations for high-speed signaling compatibility.
- Delivers high-speed performance with sub-nanosecond propagation delay characteristics.
- Integrates fixed internal hysteresis to improve noise immunity during signal transitions.
Applications
- High-speed digital communication interfaces requiring fast threshold detection.
- Video signal processing circuits utilizing RSPECL standards.
- Precision timing and pulse width modulation applications.
Procurement Notes
Verify the specific suffix 'SQX' against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS3 compliance requirements as indicated by the NOPB designation. Cross-reference the 24-WQFN footprint dimensions with your PCB layout guidelines before finalizing procurement orders.
Selection Notes
Select this component when differential or RSPECL outputs are required for high-speed comparison tasks. Consider the 24-WQFN package size for space-constrained designs. Evaluate the 80dB CMRR/PSRR specifications against system noise environments. Confirm that the 2.7V minimum supply voltage aligns with the target power rails.
Part Context
This part belongs to the LMH7322 family of dual high-speed comparators. It is designed for applications demanding rapid response times and multiple output logic families. The SQX variant specifies the industrial temperature grade and specific packaging configuration within the broader product line.
Replacement Considerations
Consult the official datasheet for direct pin-compatible alternatives within the LMH7322 series. Verify functional equivalence regarding output types and propagation delays before substituting.
