SN74LS137N** is a **3-to-8 line decoder/demultiplexer** manufactured by **Motorola (MOTO)**.

The SN74LS137N is a 3-to-8 line decoder/demultiplexer manufactured by Motorola (MOTO).

Specifications:

  • Logic Family: 74LS (Low-Power Schottky)
  • Function: 3-to-8 Line Decoder/Demultiplexer
  • Number of Inputs: 3 (A0, A1, A2)
  • Number of Outputs: 8 (Y0-Y7, active-low)
  • Enable Inputs: 3 (Two active-low G1, G2A, and one active-high G2B)
  • Supply Voltage (VCC): 4.75V to 5.25V
  • Operating Temperature Range: 0°C to 70°C
  • Package: 16-pin DIP (Dual In-line Package)
  • Propagation Delay: Typically 24ns (max)
  • Power Dissipation: 45mW (typical)

Descriptions:

The SN74LS137N is designed to decode three binary address inputs (A0, A1, A2) into one of eight mutually exclusive outputs (Y0-Y7). It features three enable inputs (G1, G2A, G2B) for cascading and control. When enabled, the selected output goes low, while all others remain high.

Features:

  • Active-Low Outputs for easy interfacing with other logic circuits
  • Multiple Enable Inputs for flexible control and expansion
  • Schottky-Clamped for improved performance
  • TTL-Compatible inputs and outputs
  • Wide Operating Voltage Range (4.75V to 5.25V)

This IC is commonly used in address decoding, memory selection, and data routing applications.
