74HC126D,652

Overview

The Nexperia 74HC126D,652 is a quad buffer and line driver featuring three-state outputs controlled by active HIGH enable inputs. It operates within a supply voltage range of 2.0 V to 6.0 V and complies with JEDEC standards JESD8C and JESD7A. The device utilizes CMOS technology for low power dissipation and high noise immunity. It includes input clamp diodes to interface with voltages exceeding VCC. The component supports an ambient temperature range from -40 °C to +125 °C and provides ESD protection exceeding 2000 V (HBM) and 1000 V (CDM).

Feature Summary

• Quad buffer/line driver with three-state outputs controlled by active HIGH enable inputs.
• CMOS low power dissipation with high noise immunity.
• Input clamp diodes allow interfacing with voltages in excess of VCC.
• Latch-up performance exceeds 100 mA per JESD 78 Class II Level B.

Applications

• High-speed data bus buffering.
• Line driving applications requiring three-state control.
• General-purpose logic buffering in industrial environments.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure package compatibility and availability. Confirm that the procurement channel sources genuine Nexperia components. Check for any recent product status changes or obsolescence notices directly from the manufacturer before finalizing orders.

Selection Notes

Select this component when a quad non-inverting buffer with three-state capability is required. Ensure the system design accommodates the 2.0 V to 6.0 V supply voltage range. Verify that the SO14 plastic small outline package meets the board layout constraints. Consider the operating temperature range requirements for the intended application environment.

Part Context

This part belongs to the 74HC/HCT logic family, which is widely used in digital systems for signal buffering and driving. The 74HC series offers CMOS performance with pin compatibility to Low-power Schottky TTL (LSTTL). The 'D' suffix indicates the SO14 package variant, while '652' denotes the specific manufacturing code and tape & reel packaging configuration.

Replacement Considerations

Direct replacements include other manufacturers' equivalents such as SN74HC126 or MC74HC126. Ensure functional compatibility regarding the active HIGH enable logic and three-state output behavior. Verify that alternative packages match the physical footprint if direct substitution is required without PCB redesign.
