SN74HCT125NE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HCT125NE4 is a quad bus buffer gate with three-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible inputs. The device provides an output drive capability of ±6 mA at 5 V, with a maximum supply current of 80 µA. Propagation delay is typically 12 ns. It is housed in a 14-pin PDIP package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Contains four independent buffers with non-inverting logic functions
• Features high-current three-state outputs for driving bus lines or memory address registers
• Inputs are compatible with standard TTL voltage levels

Buffers, Drivers, Receivers, Transceivers Applications

• Driving bus lines
• Buffering memory address registers
• General-purpose digital signal buffering

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'E4' indicates lead-free composition and RoHS compliance as per manufacturer standards. Confirm the active production status and tube packaging quantity of 25 units. Ensure the selected component matches the required 14-pin PDIP form factor for your printed circuit board assembly.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when TTL-level input compatibility is required alongside CMOS performance. The HCT series ensures direct interfacing with TTL logic families without level shifting. Consider the ±6 mA drive strength sufficient for moderate capacitive loads on bus structures.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SNx4HCT125 family of quadruple bus buffer gates. It shares functional characteristics with other variants in the series but differs in physical packaging and environmental compliance markings. The NE4 designation specifically identifies the PDIP package variant with lead-free terminations.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74HCT125N serves as the primary equivalent without the environmental suffix. SN74HCT125D offers identical electrical performance in a surface-mount SOIC package.
