CD74HC237EG4

Signal Switches, Multiplexers, Decoders Overview

The CD74HC237EG4 is a high-speed CMOS logic device manufactured by Texas Instruments, functioning as a 3-to-8 line decoder/demultiplexer with address latches. It operates within a supply voltage range of 2V to 6V and supports an operating temperature range from -55°C to +125°C. The component utilizes a 16-pin SOIC surface-mount package. Key electrical characteristics include a maximum propagation delay of 20ns at 5V and output drive capabilities of 5.2mA for both high and low states.

Signal Switches, Multiplexers, Decoders Feature Summary

• Integrates address latches to maintain decoded outputs independently of input changes
• Provides three enable inputs for flexible system control and power management
• Features balanced push-pull outputs for reliable signal transmission

Signal Switches, Multiplexers, Decoders Applications

• Address decoding in microprocessor-based systems
• Data routing and demultiplexing in industrial control units
• Memory addressing circuits requiring latch functionality

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix 'E' confirms the SOIC-16 package variant distinct from other pin-out options. Confirm RoHS compliance status matches current manufacturing standards. Ensure the ordering part number aligns with the required tape-and-reel or tube packaging configuration for your assembly process.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when address latching is required alongside decoding functions. Compare against standard decoders if latching is unnecessary to reduce cost. Verify that the 2V to 6V supply range meets the target system's voltage requirements and that the SOIC package fits the PCB footprint constraints.

Signal Switches, Multiplexers, Decoders Part Context

This device belongs to the Texas Instruments 74HC series of high-speed CMOS logic components. The HC series is designed for compatibility with standard TTL logic levels while offering lower power consumption. The CD prefix indicates commercial grade temperature rating, though this specific variant supports extended industrial ranges.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Compatible substitutes include the CD74HC237M96 and CD74HC237PWR. Verify pin compatibility and package dimensions before substitution. Ensure the alternative part number maintains the same address latch functionality and enable input configuration.
