CD74HC237PWG4

Signal Switches, Multiplexers, Decoders Overview

The CD74HC237PWG4 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 output currents of 5.2mA for both high and low states. The component is housed in a 16-TSSOP package and is designed for surface-mount installation. It features three enable inputs and maintains an operating temperature range from -55°C to +125°C. The device complies with RoHS standards and carries an MSL rating of 1.

Signal Switches, Multiplexers, Decoders Feature Summary

• Integrates address latches to maintain decoded outputs independently of input changes
• Provides three distinct enable inputs for flexible system control and power management
• Supports high-speed CMOS logic operations across a wide industrial temperature range

Signal Switches, Multiplexers, Decoders Applications

• Address decoding in microprocessor-based systems
• Data distribution in digital communication circuits
• Memory chip selection in embedded storage architectures

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix 'G4' confirms lead-free and RoHS compliance status against the manufacturer's current documentation. Ensure the TSSOP-16 package dimensions match the target PCB footprint requirements. Confirm that the 3-enable input configuration aligns with the system design logic before finalizing procurement orders.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when address latching functionality is required alongside standard decoding. The HC series offers compatibility with standard 5V and 3.3V logic levels. Consider the 16-pin TSSOP form factor for space-constrained surface-mount designs requiring robust thermal performance up to 125°C.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the Texas Instruments 74HC family of high-speed CMOS logic devices. It shares functional similarities with the CD74HC238 but includes additional address latch capabilities. The device is part of a broader portfolio of decoders and demultiplexers designed for general-purpose digital logic applications.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The CD74HC238M96 is listed as a substitute option in distributor records. Verify functional equivalence regarding the address latch feature, as the 238 variant may lack this specific capability compared to the 237 model.
