74HC125D,652

Overview

The Nexperia 74HC125D,652 is a quad buffer and line driver featuring three-state outputs controlled by active LOW 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 utilizes CMOS technology for low power dissipation and high noise immunity. It complies with JEDEC standards JESD8C and JESD7A. The component is housed in a 14-lead SO plastic small outline package (SOT108-1) with a body width of 3.9 mm.

Feature Summary

• Provides four non-inverting buffers with three-state outputs controlled by dedicated enable pins.
• Features input clamp diodes allowing interface to voltages exceeding the supply voltage using current limiting resistors.
• Offers robust electrostatic discharge protection exceeding 2000 V under Human Body Model conditions.

Applications

• High-speed data bus buffering
• Line driving applications requiring signal isolation
• Voltage level translation between different logic families

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm the exact package variant and tape-and-reel specifications. Ensure that the procurement channel provides valid traceability for the SOT108-1 package type. Confirm compliance with RoHS directives as specified in the product data sheet before finalizing acquisition.

Selection Notes

Select this component when designing circuits requiring isolated signal transmission or bus holding capabilities. The wide supply voltage range accommodates various system architectures. Verify that the required propagation delay characteristics align with the target clock frequencies and load capacitance conditions defined in the dynamic specifications.

Part Context

This device belongs to the 74HC/HCT logic family, which represents standard high-speed CMOS technology compatible with Low-power Schottky TTL systems. The 74HC125 variant specifically addresses applications needing buffered outputs with controllable impedance states, distinguishing it from standard non-three-state buffers within the same series.

Replacement Considerations

The 74HCT125D,652 serves as a functional alternative if TTL-compatible input levels are required instead of CMOS levels. Other packages such as TSSOP14 may be considered if board space constraints necessitate a smaller footprint, provided pin compatibility is maintained.
