74HCT125D,652

Overview

The Nexperia 74HCT125D,652 is a quad buffer and line driver featuring three-state outputs controlled by active-low output enable inputs. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device utilizes HCT logic levels for input compatibility. It is housed in a 14-lead SO plastic small outline package (SOT108-1) with a body width of 3.9 mm.

Feature Summary

• Quad buffer/line driver configuration with independent three-state outputs
• Active-low output enable control for high impedance OFF-state management
• Input clamp diodes allow interfacing to voltages exceeding VCC using current limiting resistors
• Compliant with JEDEC standards JESD8C and JESD7A

Applications

• Bus-oriented communications systems
• Clock distribution circuits
• Memory module data buffering

Procurement Notes

Verify the specific ordering suffix matches the required tape and reel or cut tape packaging format. Confirm that the component status remains active as per the latest Nexperia product longevity program updates. Ensure compliance with REACH and RoHS directives relevant to the target market regulations before finalizing procurement orders.

Selection Notes

Select this component when TTL-compatible input levels are required alongside CMOS performance characteristics. The 74HCT125D variant is appropriate for designs operating strictly at 5 V nominal supply voltages. Consider the SO14 package dimensions for PCB layout constraints compared to TSSOP alternatives.

Part Context

This part belongs to the 74HCT series of logic integrated circuits manufactured by Nexperia. It serves as a standard interface solution for digital systems requiring signal buffering with tri-state capability. The D suffix indicates the SO14 surface-mount package type, distinguishing it from other physical form factors available within the same logical family.

Replacement Considerations

The 74HCT125D,653 is listed as a parameter-equivalent alternative offering identical electrical specifications and functionality within the same package type.
