CD74HC4515EG4

Signal Switches, Multiplexers, Decoders Overview

The CD74HC4515EG4 is a high-speed CMOS logic device manufactured by Texas Instruments, belonging to the 74HC series. It functions as a 4-to-16-line decoder or demultiplexer with inverted outputs. The component operates on a single power supply ranging from 2 V to 6 V and supports surface-mount installation in a 20-pin TSSOP package. It features address latches for input data retention and is rated for an operating temperature range of -55°C to +125°C.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides one-of-sixteen decoding capability with active-low outputs
• Includes address latches to maintain output states independent of input changes
• Compatible with standard CMOS logic families for system integration

Signal Switches, Multiplexers, Decoders Applications

• Data routing and signal distribution systems
• Memory address decoding circuits
• Industrial control logic interfaces

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific EG4 suffix against official Texas Instruments documentation to confirm lead-free status and RoHS compliance. Ensure the ordering part number matches the required TSSOP-20 package variant. Cross-reference the manufacturer's latest datasheet to validate current production status and environmental certifications before finalizing procurement specifications.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a 4-to-16 decoder with inverted outputs and internal address latching is required. The HC series offers higher speed compared to legacy counterparts while maintaining low power consumption. Verify that the 2V to 6V voltage range aligns with the target system's power supply constraints and that the wide temperature rating meets the operational environment requirements.

Signal Switches, Multiplexers, Decoders Part Context

This device is part of the broader 74HC family of high-speed CMOS logic integrated circuits produced by Texas Instruments. It serves as a functional equivalent to other industry-standard 4-to-16 decoders but is distinguished by its specific latch configuration and inverted output polarity. The EG4 designation typically indicates a lead-free and environmentally compliant version of the standard CD74HC4515E model.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Direct substitutes include the CD74HC4515E and CD74HC4515M96. Verify pinout compatibility and electrical characteristics such as propagation delay and output drive current when transitioning between these variants.
