Overview
The Nexperia 74HC238PW-Q100J is an automotive-grade 3-to-8 line decoder and demultiplexer housed in a 16-pin TSSOP package. It decodes three binary weighted address inputs to eight mutually exclusive active HIGH outputs. The device operates on a single power supply ranging from 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. It complies with AEC-Q100 Grade 1 standards, ensuring suitability for demanding automotive environments.
Feature Summary
- Automotive qualification compliant with AEC-Q100 Grade 1 standards
- Demultiplexing capability using active LOW enable inputs as data strobes
- Multiple input enable configuration facilitating easy parallel expansion
- Input clamp diodes enabling interface to voltages exceeding VCC
Applications
- Memory chip select decoding
- Parallel expansion of decoder systems
- Automotive electronic control units
Procurement Notes
Verify the specific ordering suffix matches the required package variant. Confirm that the component meets the intended environmental temperature range requirements. Ensure design compatibility with the specified logic family voltage levels before integration into the final assembly.
Selection Notes
Select this component when an automotive-qualified decoder is required for memory addressing or signal routing. The TSSOP16 package offers a compact footprint suitable for space-constrained designs. Verify that the CMOS input levels align with the driving source logic family specifications.
Part Context
This part belongs to the Nexperia 74HCT238-Q100 series of 3-to-8 line decoders. It shares functional characteristics with other variants in the family but utilizes the PW suffix to denote the specific TSSOP16 plastic thin shrink small outline package configuration.
Replacement Considerations
Direct substitutes include the 74HC238D-Q100J (SO16 package) and the 74HC238BQ-Q100X (DHVQFN16 package). These alternatives maintain identical electrical functionality while offering different physical mounting profiles.
