74HCT125N,652

Overview

The Nexperia 74HCT125N,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 4.5 V to 5.5 V. The device accepts TTL-level inputs and provides non-inverting buffering. It is housed in a 14-lead plastic dual in-line package (DIP14). The component supports an operating temperature range from -40 °C to +125 °C.

Feature Summary

• Provides four independent non-inverting buffers with high-speed CMOS performance
• Features three-state outputs that enter a high-impedance OFF-state when disabled
• Includes input clamp diodes to facilitate interfacing with voltages exceeding the supply rail

Applications

• Bus-oriented architectures requiring data isolation
• Clock distribution networks for timing signals
• Memory address decoding circuits
• Drive capacitive loads in digital logic systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product status documentation. Confirm that the DIP14 package variant matches the required mechanical footprint and lead configuration for the target printed circuit board design before finalizing procurement orders.

Selection Notes

Select this component when a quad buffer with three-state control is required for 5 V logic systems. Ensure the application utilizes TTL-compatible input levels. Verify that the thermal dissipation requirements align with the specified power derating curves for the DIP14 package under maximum ambient temperature conditions.

Part Context

This part belongs to the 74HCT series of high-speed silicon-gate CMOS logic devices. It maintains pin compatibility with low-power Schottky TTL standards. The device complies with JEDEC standard no. 7A specifications for digital integrated circuits, ensuring interoperability within standard logic families.

Replacement Considerations

The 74HCT125N is functionally equivalent to other manufacturers' quad bus drivers with three-state outputs. Cross-reference the DIP14 package dimensions and electrical characteristics with alternative suppliers to ensure direct replacement capability without circuit modification.
