74HC126PW,112

Overview

The Nexperia 74HC126PW,112 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 utilizes a TSSOP14 package (SOT402-1). The device provides non-inverting logic with high noise immunity and low power CMOS dissipation. Input clamp diodes allow interfacing with voltages exceeding VCC using current limiting resistors. It complies with JEDEC standards JESD8C and JESD7A.

Feature Summary

• Quad buffer/line driver with three-state outputs
• Active HIGH output enable control
• Input clamp diodes for overvoltage tolerance
• High noise immunity and low power consumption

Applications

• Bus-oriented transmissions
• Clock buffering and distribution
• Memory data bus drivers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and tape-and-reel specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or Nexperia sales offices prior to procurement planning.

Selection Notes

Select this component when a quad non-inverting buffer with three-state capability is required. Ensure the system design accommodates the active HIGH enable logic. Verify that the operating voltage falls within the specified 2.0 V to 6.0 V range and that the TSSOP14 package fits the PCB layout constraints.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices manufactured by Nexperia. It is functionally compatible with standard 74HC logic families but offers specific packaging in the thin shrink small outline format. It serves as a fundamental building block for digital signal routing and isolation in mixed-voltage environments.

Replacement Considerations

Check for direct pin-compatible alternatives such as the 74HCT126 variant if TTL input levels are required instead of CMOS levels. Verify equivalent packages from other manufacturers like NXP Semiconductors or onsemi, ensuring identical electrical characteristics and pinout configurations.
