LMH7220MK/NOPB

Overview

The LMH7220MK/NOPB is a high-speed comparator manufactured by Texas Instruments, featuring Low Voltage Differential Signaling (LVDS) outputs. It operates within a supply voltage range of 3 V to 5.5 V and draws a typical quiescent current of 14 mA per channel. The device provides a propagation delay of 280 ps and a slew rate of 6000 V/µs. It supports rail-to-rail input common-mode voltages and includes an integrated reference buffer. The component is housed in a 16-pin TSSOP package and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates LVDS-compatible differential outputs for high-speed signal transmission with reduced electromagnetic interference.
• Features rail-to-rail input capability allowing full common-mode voltage swing from negative to positive supply rails.
• Includes an internal reference buffer to maintain stable threshold levels under varying load conditions.

Applications

• High-speed data acquisition systems requiring precise timing discrimination.
• Optical communication receivers utilizing differential signaling interfaces.
• Test and measurement equipment demanding fast transient response.

Procurement Notes

Verify the specific suffix MK against official Texas Instruments documentation to confirm the 16-pin TSSOP packaging and industrial temperature grade. Ensure compatibility with LVDS receiver inputs in the target circuit design. Cross-reference the datasheet revision date to confirm parameter stability before finalizing procurement specifications.

Selection Notes

Select this component when differential output signaling is required to minimize noise in high-frequency applications. The integrated reference buffer simplifies biasing networks compared to standard comparators. Evaluate power consumption constraints as the LVDS drivers draw significant quiescent current relative to low-power CMOS alternatives.

Part Context

This part belongs to the LMH7220 family of high-speed comparators designed for demanding signal processing tasks. It bridges the gap between general-purpose comparators and specialized RF components by offering both speed and differential output capabilities. The NOPB suffix indicates compliance with RoHS standards and absence of lead-based materials.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify functional equivalence with other LVDS-output comparators such as the TLV3604 series only if electrical parameters match exactly.
