MC74AC125D

Overview

The MC74AC125D is a quad 3-state buffer manufactured by onsemi using high-performance silicon-gate CMOS technology. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient operating temperature from -40°C to +85°C. The device features four non-inverting inputs and outputs capable of sourcing or sinking up to 24 mA. Propagation delay is specified at 9 ns maximum at 3.3 V and 7 ns maximum at 5.0 V with a 50 pF load.

Feature Summary

• Provides four independent non-inverting buffers with low-enable control for signal buffering and line driving applications.

Applications

• Signal buffering in digital logic circuits
• Line driving for data transmission paths

Procurement Notes

Verify the specific package suffix 'D' corresponds to the SOIC-14 configuration as documented in the ordering information section. Confirm that the procurement order explicitly references the MC74AC125D part number to ensure correct identification of the AC series variant rather than the ACT series. Ensure compliance with RoHS requirements indicated by the Pb-Free designation.

Selection Notes

Select this component when a quad buffer with 3-state output capability is required for 2V to 6V CMOS logic systems. Consider the propagation delay specifications relative to system timing requirements. Verify that the input voltage levels are compatible with the driving source logic family before implementation.

Part Context

This component belongs to the MC74AC125 product family, which includes variants such as the MC74ACT125. The AC series utilizes standard CMOS thresholds, whereas the ACT series offers TTL-compatible inputs. Both share similar physical packaging options including SOIC-14 and TSSOP-14 configurations.
