CD4515BCN

Signal Switches, Multiplexers, Decoders Overview

The CD4515BCN is a 4-to-16 line decoder with latched inputs implemented using complementary MOS (CMOS) technology. It operates on a single supply voltage ranging from 3.0V to 15V and features an operating temperature range of -55°C to +125°C. The device utilizes R-S type flip-flops for input latching, holding data prior to the strobe transition. It presents a logical '0' at the selected output and includes an output inhibit line. The component is housed in a 24-Lead Plastic Dual-In-Line Package (PDIP).

Signal Switches, Multiplexers, Decoders Feature Summary

• Features R-S type flip-flop input latches that hold data before decoding.
• Provides active low outputs at the selected line while others remain inactive.
• Includes a dedicated output inhibit line for controlling signal transmission.
• Offers high noise immunity suitable for environments requiring low power dissipation.

Signal Switches, Multiplexers, Decoders Applications

• Decoding applications requiring low power dissipation and high noise immunity.
• Complex data routing systems utilizing multiple data selectors.
• Sequential data re-routing or intermixing according to specific patterns.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the manufacturer origin, as datasheets reference Fairchild Semiconductor while distributors list onsemi. Confirm the package style matches the required 24-pin DIP configuration. Check for RoHS compliance status if environmental regulations apply to the target assembly. Ensure the specific suffix aligns with the desired packaging variant.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a 4-bit addressable decoder with internal latching is required. It is appropriate for designs needing a wide supply voltage range and industrial temperature operation. Consider the active low output characteristic when interfacing with downstream logic gates. Verify compatibility with existing TTL fan-out requirements if driving legacy logic families.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the CD4514/CD4515 series of CMOS logic devices. It serves as a functional complement to the CD4514, which provides active high outputs. Both devices share identical pinouts and latch mechanisms but differ in output polarity. They are designed for general-purpose decoding tasks within standard digital logic circuits.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Direct plug-in replacements include MC14514 and MC14515 variants. Cross-reference specifications to ensure equivalent latch behavior and output drive capabilities match the original design requirements.
