Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the ordering suffix '112' corresponds to the TSSOP16 package variant when sourcing. Confirm that the specific batch meets the required temperature grade specifications for your application environment. Ensure compatibility with standard surface-mount assembly processes compatible with the SOT403-1 outline dimensions.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when TTL-level inputs are required alongside CMOS performance characteristics. The 3-state output capability allows for efficient bus sharing without additional buffering components. Consider the TSSOP16 package for applications requiring higher pin density compared to standard SO packages while maintaining thermal performance within the specified operating range.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74HCT series, which bridges TTL logic levels with CMOS technology. It shares functional similarities with the 74HC257 but differs in input threshold voltages to accommodate TTL signals. The PW suffix specifically denotes the TSSOP16 package type, distinguishing it from other physical form factors available within the same logical family.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Direct replacements must match the 74HCT logic family and TSSOP16 package. Verify that substitute parts maintain identical pin configurations and 3-state output functionality. Cross-reference with manufacturer datasheets to ensure equivalent electrical parameters and operating temperature ranges.
