74HC125N,652

Overview

The NXP 74HC125N,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 2.0 V to 6.0 V and complies with JEDEC standard no. 7A. The device includes input clamp diodes for interfacing with voltages exceeding VCC. It provides ESD protection exceeding 2000 V (HBM) and 200 V (MM). The component is specified for operation from -40 °C to +125 °C and utilizes a 14-lead plastic dual in-line package.

Feature Summary

• Quad buffer/line driver with three-state outputs
• Active-low output enable control
• Input clamp diodes for over-voltage interfacing
• High ESD protection ratings

Applications

• Bus-oriented systems
• Clock buffering and distribution
• Memory address/data bus drivers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature range specifications. Ensure compatibility with system voltage levels and load requirements before finalizing procurement decisions.

Selection Notes

Select this component when a quad buffer with three-state capability is required for bus isolation or signal driving. Consider the HC logic family for CMOS input/output characteristics and verify that the DIP14 package meets the physical layout constraints of the target design.

Part Context

This part belongs to the 74HC/HCT logic family, which is widely used in digital electronics for general-purpose logic functions. The 74HC125 specifically addresses applications requiring signal buffering with high impedance states to prevent bus contention.

Replacement Considerations

Compatible replacements include other manufacturers' 74HC125 variants in DIP14 packages, such as those from Texas Instruments or ON Semiconductor, provided they meet the same electrical and mechanical specifications.
