MC14555BFEL

Overview

The MC14555BFEL is a dual binary to 1-of-4 decoder/demultiplexer constructed with complementary MOS (CMOS) enhancement mode devices. It features two select inputs, an active low enable input, and four mutually exclusive outputs per channel. The device operates within a supply voltage range of 3.0 Vdc to 18 Vdc. It includes diode protection on all inputs and offers buffered outputs capable of driving two Low-Power TTL loads or one Low-Power Schottky TTL load.

Feature Summary

• Diode protection integrated on all inputs
• Active high output configuration for selected channels
• Expandable architecture for complex decoding applications
• Buffered outputs compatible with standard TTL logic families

Applications

• Code conversion systems
• Address decoding circuits
• Memory selection control
• Demultiplexing in digital data transmission

Procurement Notes

Verify the specific ordering suffix 'FEL' corresponds to the SOEIAJ-16 package and tape & reel shipping format as listed in official documentation. Confirm that the component meets Pb-Free requirements if environmental compliance is mandatory for the target assembly process.

Selection Notes

Select this component when a dual-channel decoder with active high outputs is required. Ensure the application voltage remains within the specified 3.0 Vdc to 18 Vdc range. Consider the MC14556B variant if active low outputs are preferred instead.

Part Context

This part belongs to the MC14555B/MC14556B family of CMOS decoders. It serves as a direct functional equivalent to legacy bipolar counterparts but utilizes modern CMOS technology for lower power consumption and higher noise immunity while maintaining pin compatibility.
