SN74HC151N

Overview

The SN74HC151N is an 8-line to 1-line data selector/multiplexer from Texas Instruments, belonging to the 74HC logic family. It provides complete binary decoding to select one of eight data sources. The device features a strobe input that forces the standard output (Y) low and the complementary output (Yn) high when active. It operates within a supply voltage range of 2V to 6V, ensuring compatibility with various digital systems.

Feature Summary

• Provides complete binary decoding for selecting one of eight data inputs
• Includes active-low strobe functionality to control output states
• Delivers both standard and complementary outputs for flexible logic interfacing

Applications

• Data routing in digital communication systems
• Address decoding in memory structures
• Implementation of combinational logic functions

Procurement Notes

Verify the package type corresponds to the 'N' suffix, indicating a PDIP-16 through-hole configuration. Confirm the logic family is HC (High-speed CMOS) rather than HCT or LS variants. Ensure the component meets required operating temperature ranges for your specific application environment before procurement.

Selection Notes

Select this component when an 8-channel multiplexing function is required with CMOS compatibility. The HC series offers higher speed than standard 74C devices while maintaining low power consumption. Consider the PDIP-16 package if through-hole mounting is necessary for prototyping or specific board layouts.

Part Context

This part belongs to the Texas Instruments 74HC series of high-speed CMOS logic devices. The 74HC151 specifically addresses the need for multi-channel data selection within standard digital logic families. It serves as a fundamental building block for complex digital circuits requiring signal routing capabilities.

FAQ

What is the function of the strobe input?

The strobe input disables the device; when active, it forces the standard output low and the complementary output high regardless of the address inputs.

Does this device provide complementary outputs?

Yes, the SN74HC151N provides both a standard output (Y) and a complementary output (Yn).
