MC14556BCP

Overview

The MC14556BCP is a dual binary to 1-of-4 decoder/demultiplexer manufactured by onsemi. It utilizes complementary MOS (CMOS) enhancement mode devices and features two select inputs, an active low enable input, and four mutually exclusive outputs per channel. The selected output transitions to the low state. It operates within a supply voltage range of 3.0 Vdc to 18 Vdc and supports ambient temperatures from -55°C to +125°C. The component is housed in a PDIP-16 package.

Feature Summary

• Dual independent decoding channels with four mutually exclusive outputs each
• Active low enable input for channel control
• Diode protection provided on all inputs
• Capable of driving low-power TTL loads

Applications

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

Procurement Notes

Verify the specific ordering suffix to confirm package type and lead-free status. Confirm RoHS compliance requirements against the manufacturer's current documentation. Check for any product change notices or obsolescence alerts prior to finalizing procurement plans.

Selection Notes

Select this component when dual 1-of-4 decoding functionality is required within a single integrated circuit. Ensure the application logic aligns with the active low enable and low-state output characteristics. Verify that the CMOS technology meets the power consumption and drive current needs of the target system.

Part Context

This device belongs to the MC1455xB series of standard CMOS logic components. It serves as the inverted-output counterpart to the MC14555B, which provides high-state outputs. Both devices share identical pinouts and electrical specifications, differing only in the logic level of the active output.
