CD74HC237E

Signal Switches, Multiplexers, Decoders Overview

The CD74HC237E is a high-speed silicon-gate CMOS decoder/demultiplexer manufactured by Texas Instruments. It features a single 3-to-8 line decoder with address latches and three enable inputs. The device operates within a supply voltage range of 2V to 6V and supports an operating temperature range from -55°C to +125°C. It utilizes a 16-pin DIP package.

Signal Switches, Multiplexers, Decoders Feature Summary

• Integrates address latches to isolate output changes from input variations via a latch enable signal.
• Includes two output enable inputs to facilitate cascading and demultiplexing functions.
• Provides non-inverting outputs for selected lines.

Signal Switches, Multiplexers, Decoders Applications

• Memory address decoding in shared bus systems
• Data routing and distribution
• Demultiplexing applications

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix 'E' corresponds to the 16-pin PDIP package configuration. Confirm RoHS compliance status and moisture sensitivity level requirements for the intended assembly process. Ensure the logic family matches system voltage levels, as HC series differs from HCS or HCT variants.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when non-inverting decoded outputs are required, distinguishing it from the CD74HC137 which provides inverted outputs. Consider the wide operating temperature range and low power consumption characteristics suitable for general-purpose digital logic applications requiring address latching capabilities.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the CD74HC237/CD74HCT237 family of high-speed CMOS logic devices. It shares functional similarities with the CD74HC137 but offers non-inverting outputs instead of active-low selections. The device is designed for memory addressing and data routing tasks where stable output states are critical during input transitions.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The CD74HC137 serves as a functional alternative if inverted (active-low) outputs are acceptable. Cross-reference datasheets for pinout compatibility and electrical parameter alignment before substitution.
