DM74LS125AN

Overview

The DM74LS125AN is a Quad 3-STATE Buffer manufactured by onsemi, housed in a 14-Lead Plastic Dual-In-Line Package (PDIP). It operates within a supply voltage range of 4.75 V to 5.25 V and an ambient temperature range of 0 °C to +70 °C. The device features four independent non-inverting gates with high-impedance outputs when disabled. Electrical characteristics include a low-level output current of 24 mA and a high-level output current of -2.6 mA at minimum supply voltage.

Feature Summary

• Contains four independent non-inverting buffer gates
• Outputs exhibit 3-STATE functionality for bus driving
• Disable time is shorter than enable time to prevent bus contention

Applications

• Driving bus lines without external resistors
• General-purpose buffering in digital logic circuits
• System interconnects requiring tri-state isolation

Procurement Notes

Verify the specific ordering code suffix against the manufacturer's documentation to confirm package type and tape/reel availability. Confirm RoHS compliance status as historical data may vary. Ensure the component meets the required operating temperature range for the intended application environment before finalizing procurement.

Selection Notes

Select this component for applications requiring quad non-inverting buffers with tri-state control. Verify that the load capacitance requirements fall within the specified switching characteristic limits. Ensure the design accommodates the recommended operating conditions for supply voltage and free air temperature to maintain electrical performance.

Part Context

This part belongs to the 74LS logic family, characterized by low-power Schottky technology. It serves as a standard interface buffer in legacy and industrial systems. The PDIP-14 package facilitates through-hole mounting on printed circuit boards, supporting manual assembly or wave soldering processes common in older manufacturing standards.
