74HCT126PW,118

Overview

The Nexperia 74HCT126PW,118 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 4.5 V to 5.5 V. The device provides four non-inverting buffers with high-impedance OFF-states when disabled. It utilizes the TSSOP14 package (SOT402-1) and supports an operating temperature range from -40 °C to +125 °C.

Feature Summary

• Quad buffer/line driver with three-state outputs
• Active HIGH output enable control
• TTL input levels for HCT logic family
• High noise immunity and low power dissipation

Applications

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

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the component meets RoHS3 compliance standards as specified in the product documentation. Ensure the selected part number corresponds to the correct temperature grade and pin configuration before finalizing procurement orders.

Selection Notes

Select this component when TTL-compatible input thresholds are required alongside CMOS drive capabilities. The active HIGH enable signal distinguishes it from similar devices with active LOW enables. Verify that the application environment remains within the specified thermal limits for reliable operation.

Part Context

This component belongs to the 74HCT series of logic integrated circuits manufactured by Nexperia. It serves as a standard interface solution for digital systems requiring signal isolation or line driving. The PW suffix indicates the TSSOP14 plastic thin shrink small outline package format.

Replacement Considerations

Direct functional substitutes include the 74HC126PW,118 for CMOS input compatibility and the 74VHCT126PW,118 for high-speed performance. Verify pinout compatibility and electrical specifications before substituting.
