74HC237D-Q100J

Overview

The Nexperia 74HC237D-Q100J is a 3-to-8 line decoder and demultiplexer featuring address latches, designed for automotive applications. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C. The device integrates three-bit storage latches at the address inputs (A0, A1, A2) controlled by a latch enable input (LE). It utilizes a 16-lead SO plastic small outline package (SOT109-1). Propagation delays vary with voltage, ranging from 27 ns to 41 ns at 6.0 V.

Feature Summary

• Combines 3-to-8 decoding functionality with integrated 3-bit address latching
• Qualified to AEC-Q100 Grade 1 standards for automotive environments
• Features multiple input enables for system expansion or independent control
• Provides active HIGH mutually exclusive outputs

Applications

• Implementing non-overlapping decoders in 3-state systems
• Storing addresses in bus-oriented systems
• Expanding decoder capabilities in complex logic circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct package type and temperature grade. Confirm that the component meets the required AEC-Q100 Grade 1 qualification status for the intended automotive application environment before finalizing procurement specifications.

Selection Notes

Select this component when a design requires simultaneous decoding and address storage without external latching circuitry. Ensure the operating voltage aligns with the 2.0 V to 6.0 V specification. Verify that the SO16 package dimensions fit the available PCB footprint and that the thermal dissipation requirements are met within the specified temperature range.

Part Context

This part belongs to the Nexperia 74HC series of high-speed CMOS logic devices. The Q100 designation indicates automotive qualification under AEC-Q100 standards. The D suffix identifies the SO16 plastic small outline package variant. It serves as a specialized logic IC combining decoding and memory functions for address management.

Replacement Considerations

Check for direct equivalents such as the 74HCT237D-Q100J if TTL-compatible inputs are required instead of CMOS levels. Verify pinout compatibility and electrical characteristics before substituting with other 3-to-8 decoders lacking integrated address latches.
