SN54SC8T151MPWTSEP

Signal Switches, Multiplexers, Decoders Overview

The SN54SC8T151MPWTSEP is a radiation-tolerant, eight-line to one-line data selector/multiplexer with an integrated logic-level shifter. Manufactured by Texas Instruments under the SN54SC series, this component operates within a supply voltage range of 0.65 V to 3.6 V. It features full binary decoding to select one of eight data sources and includes a strobe (G) input that must be low to enable selection. The device is housed in a 24-pin TSSOP package and supports operation temperatures from -55°C to +125°C.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the complete part number including the MP suffix and PW package code against official Texas Instruments documentation. Confirm radiation tolerance specifications and operating temperature ranges match mission requirements. Ensure compatibility with existing board layouts for the TSSOP-24 footprint. Cross-reference vendor item drawings for assembly details.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when radiation hardness is critical alongside voltage level translation capabilities. The integrated shifter simplifies interface design between different logic families. Verify that the 50krad(Si) TID rating meets environmental exposure limits. Consider the TSSOP-24 package constraints for thermal management and pin density in compact designs.
