SN74F151BDBR

Overview

The SN74F151BDBR is an 8-to-1 line data selector/multiplexer from the Texas Instruments SN74F series. It features eight digital inputs, three address select lines, and a single output with complementary outputs (Y and W). The device operates on a supply voltage range of 4.5 V to 5.5 V. It is housed in a 16-pin TSSOP package designed for surface-mount technology applications.

Feature Summary

• Provides high-speed data routing via F-series logic architecture
• Offers complementary true and inverted outputs for flexible interfacing
• Utilizes a compact surface-mount package for automated assembly

Applications

• Data acquisition systems requiring signal selection
• Digital communication equipment for channel switching
• Microprocessor-based control systems for input multiplexing

Procurement Notes

Verify the specific suffix 'DBR' confirms the TSSOP-16 package and reel packaging configuration. Ensure compatibility with 5V logic levels and check for RoHS compliance status in the latest manufacturer documentation before integration into production designs.

Selection Notes

Select this component when high propagation speed is required compared to standard LS or HC families. It serves as a direct functional replacement for other 8-to-1 multiplexers in the 74F family, provided the surface-mount footprint and voltage specifications align with the target circuit design requirements.

Part Context

This part belongs to the Texas Instruments SN74F logic family, known for fast switching speeds. It functions as a digital multiplexer, directing one of eight input signals to a single output based on binary address inputs. The device is widely used in digital electronics for data routing tasks.

Replacement Considerations

Compatible substitutes include SN74F251 variants which offer tri-state outputs. Other 8-to-1 multiplexers in the 74F series may be considered if pinout and electrical characteristics match the existing design constraints.
