The 74LS151 is a digital integrated circuit by Texas Instruments functioning as an 8-Line to 1-Line Data Selector/Multiplexer. Built with Low-power Schottky (LS) technology, it enables high-speed selection of one of eight data sources. It is perfectly suited for 5V TTL digital logic applications and comes in a convenient Through-Hole DIP-16 package.

 

74LS151 8-to-1 Data Selector/Multiplexer

The 74LS151 integrated circuit (IC) is an 8-channel digital multiplexer. Its primary function is to route one of eight input signals to a single output based on a 3-bit binary address. Based on reliable TTL (Transistor-Transistor Logic) architecture, it is widely used for data routing, signal selection, and generating Boolean functions.

Key Features

  • Operating Voltage: Standard 5V operation (Range: 4.75V to 5.25V).
  • Logic Type: 8-Line to 1-Line Data Selector/Multiplexer.
  • Technology: Low-power Schottky (LS) ensuring high-speed switching (typical propagation delay of 14ns) with low current consumption (typ. 6mA).
  • Outputs: Provides complementary outputs (True and Inverted / Y and W) for added flexibility.
  • Mounting Type: Through-Hole, making it ideal for breadboard prototyping and custom PCBs.

Pinout Overview

The DIP-16 package features the following configuration for power, data input, and selection:

  • Pin 8: GND (Ground)
  • Pin 16: VCC (+5V Power Supply)
  • Pins 11, 10, 9: Data Select Inputs (A, B, C) - Determine which input is routed to the output.
  • Pins 4, 3, 2, 1, 15, 14, 13, 12: Data Inputs (D0 - D7).
  • Pin 7: Strobe / Enable Input (Active LOW).
  • Pins 5, 6: Outputs (Y and W/Inverted).
