Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the manufacturer origin carefully, as Harris Corporation's semiconductor assets were acquired by Texas Instruments. Ensure the specific suffix 'E' corresponds to the PDIP-16 package variant. Confirm RoHS compliance status, as older Harris-branded units may not meet current environmental regulations. Cross-reference datasheets to confirm electrical characteristics match the intended application requirements before procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when dual independent 4-to-1 multiplexing is required in a compact DIP package. Consider the HC series speed and power trade-offs compared to HCT or AC variants. Verify that the 2V to 6V supply range aligns with the system's power rails. Ensure the industrial temperature range meets the operational environment specifications. Check pinout compatibility if replacing existing designs.

Signal Switches, Multiplexers, Decoders Part Context

This component is part of the widely used 74HC logic family, known for its compatibility with standard TTL logic levels while offering CMOS advantages. The CD74HC153 specifically addresses the need for multiple data selectors in space-constrained designs. Harris Corporation was a significant producer of this logic family before industry consolidation. The E suffix typically denotes the plastic DIP packaging format common through-hole applications.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Texas Instruments SN74HC153E is the primary direct replacement following the acquisition of Harris Semiconductor assets. Other compatible alternatives include the MC74HC153AN from ON Semiconductor and the HD74HC153P from Renesas. Verify pinout and electrical specifications match exactly when substituting.
