SN74LS151NG4

Overview

The SN74LS151NG4 is an 8-input multiplexer from the Texas Instruments SN74LS151 series. It features a 16-pin PDIP package for through-hole mounting. The device operates with a supply voltage range of 4.75V to 5.25V and supports CMOS/TTL outputs. It functions as a single 8-to-1 data selector with complete binary decoding. The component is rated for commercial operating temperatures between 0°C and 70°C.

Feature Summary

• Provides complete binary decoding to select one of eight data sources
• Supports both CMOS and TTL output logic levels
• Includes a strobe input for controlling standard and complementary outputs

Applications

• Digital logic circuit design
• Microcontroller system display interfaces
• Implementation of Boolean logic functions

Procurement Notes

Verify the specific suffix 'G4' against official Texas Instruments documentation to confirm RoHS compliance status and manufacturing details. Ensure the procurement channel provides valid traceability for this through-hole component. Confirm that the 16-pin PDIP form factor matches the target PCB footprint requirements before finalizing orders.

Selection Notes

Select this component when an 8-channel data selection function is required within standard 5V logic systems. It is suitable for designs needing simultaneous standard and inverted outputs. Consider alternative packages if surface-mount technology is preferred, or different logic families if wider voltage ranges are necessary.

Part Context

This part belongs to the SN74LS151 family of 8-input multiplexers. It serves as a fundamental building block in digital electronics for routing multiple signals to a single line based on address inputs. The LS series offers specific speed and power characteristics distinct from HC or AC variants.

Replacement Considerations

Compatible substitutes include the SN74LS151N and SN74LS151D. Verify pinout compatibility and electrical specifications before substituting.
