MC14555BCP

Overview

The MC14555BCP is a dual binary to 1-of-4 decoder/demultiplexer manufactured by onsemi. It features two independent decoders, each with two select inputs (A and B), an active low enable input (E), and four mutually exclusive outputs (Q0-Q3). Constructed with CMOS enhancement mode devices, it operates within a supply voltage range of 3.0 Vdc to 18 Vdc. The package is PDIP-16.

Feature Summary

• Diode protection on all inputs
• Active high or active low outputs available
• Expandable for larger decoding applications
• Capable of driving TTL loads

Applications

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

Procurement Notes

Verify the specific suffix 'CP' corresponds to the PDIP-16 package configuration as listed in the ordering information. Confirm RoHS compliance status if required, noting that Pb-free packages are available under different suffixes such as 'PG'. Ensure the device meets the required operating temperature range of -55°C to +125°C for your application environment.

Selection Notes

Select this component when dual independent 1-of-4 decoding is required within a single package. Consider the MC14556B variant if active low outputs are preferred over the active high outputs provided by the MC14555B. Ensure the design accommodates the buffered outputs capable of driving standard TTL loads across the rated temperature range.

Part Context

This part belongs to the MC14555B/MC14556B family of dual binary to 1-of-4 decoder/demultiplexers. These devices are constructed using complementary MOS technology and are designed for general-purpose decoding tasks in digital systems. The family allows for expanded decoding configurations when multiple units are utilized together.

Replacement Considerations

Direct substitutes include the MC14556BCP for active low output variants. Other compatible logic families may require level shifting or interface adjustments due to differences in drive strength or switching characteristics.
