MC74AC157DR2G

Overview

The MC74AC157DR2G is a high-speed quad 2-input multiplexer manufactured by onsemi. It features four bits of data selection from two sources using common Select and Enable inputs, presenting selected data in true form. The device operates on a single power supply ranging from 2V to 6V. It provides output source and sink currents of 24mA each. The component is housed in a 16-lead SOIC package with a D suffix.

Feature Summary

• Quad 2-input multiplexer structure for selecting four bits of data
• Outputs capable of sourcing and sinking 24 mA current
• Common Select and Enable inputs control data routing
• Pb-Free packaging compliant with environmental standards

Applications

• Moving data between register groups to common output buses
• Function generation implementing gating functions
• Logic implementation of 4-pole, 2-position switches

Procurement Notes

Verify the specific ordering suffix DR2G corresponds to the SOIC-16 tape and reel configuration. Confirm RoHS compliance status and check for any recent Product Change Notices regarding manufacturing site or material updates before finalizing procurement specifications.

Selection Notes
