74HC126N,652

Overview

The NXP 74HC126N,652 is a quad buffer/line driver with 3-state outputs controlled by active HIGH output enable inputs. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C. The device features CMOS input levels, ESD protection exceeding 2000 V (HBM) and 200 V (MM), and complies with JEDEC standard no. 7A. Propagation delay ranges from 9 ns to 100 ns depending on voltage and temperature.

Feature Summary

• Quad buffer/line driver with 3-state outputs
• Active HIGH output enable control
• ESD protection compliant with JESD22 standards

Applications

• Bus driving applications
• Line drivers for signal transmission
• Buffering digital signals in CMOS logic systems

Procurement Notes

Verify the specific ordering suffix '652' against current NXP documentation to confirm package type and tape/reel specifications. Ensure the procurement channel provides valid traceability for industrial grade components operating up to +125 °C. Confirm RoHS compliance status as per the latest product data sheet revision.

Selection Notes

Select this component when a non-inverting quad buffer with high-impedance OFF-state capability is required. It is suitable for interfacing between different voltage domains or driving multiple loads on a shared bus. Verify that the application requires active HIGH enable logic rather than active LOW.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices manufactured by NXP Semiconductors. It is functionally similar to the 74HC125 but utilizes active HIGH enable inputs instead of active LOW. The DIP14 package variant is designated by the 'N' suffix in the part number.

Replacement Considerations

The 74HC125N serves as a functional substitute if the design accommodates active LOW enable inputs instead of active HIGH. Other compatible alternatives include variants from the 74HCT126 family for TTL-compatible input levels.
