Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix 'N' confirms the PDIP-16 through-hole package variant. Confirm RoHS compliance status as indicated in official documentation. Ensure the source document explicitly lists this part number to avoid confusion with surface-mount equivalents like the DW or PW variants. Cross-reference the manufacturer's latest datasheet for any recent product change notifications affecting pinout or electrical specifications.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when an 8-to-1 multiplexing function is required in a through-hole design. The ACT series offers faster switching speeds compared to standard LS logic while maintaining CMOS power efficiency. Verify that the system voltage aligns with the 4.5 V to 5.5 V operating range. Consider the 12 ns propagation delay against your system timing requirements to ensure signal integrity is maintained.

Signal Switches, Multiplexers, Decoders Part Context

This device belongs to the SN74ACT11 series, which utilizes advanced silicon-gate CMOS technology. It is designed to be compatible with TTL logic levels while offering improved performance over previous generations. The ACT family is characterized by its ability to operate at higher frequencies than standard AC devices, making it suitable for demanding digital applications requiring reliable data selection.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The SN74HC11151N serves as a functional alternative with similar pinouts but different speed and drive characteristics. The SN74AC11151N offers comparable performance in the same package. Verify compatibility with existing circuitry before substitution, particularly regarding output current limits and propagation delays.
