Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix 'N' confirms the PDIP-16 through-hole package variant. Confirm RoHS compliance status via the manufacturer datasheet as requirements vary by region. Ensure the operating environment stays within the specified -40°C to +85°C range to maintain signal integrity and device longevity.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when an octal multiplexer with ACT speed and drive characteristics is required. Compare against the SOIC or TSSOP variants if surface-mount assembly is preferred. Verify that the 3V logic compatibility of the ACT series meets the system interface requirements.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the Texas Instruments 74ACT family, known for CMOS performance with TTL compatibility. The 11251 designation specifically identifies it as an octal multiplexer. It serves as a standard solution for multi-channel signal selection in general-purpose digital logic applications.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Check for equivalent parts such as the SN74ACT11251DR (SOIC package) or SN74ACT11251PW (TSSOP package) for pin-compatible alternatives. Verify functional equivalence with other 74ACT octal multiplexers from different manufacturers.
