AY-5-8116** is a **General Instrument (GI) 4-bit arithmetic logic unit (ALU) slice** integrated circuit (IC).

The AY-5-8116 is a General Instrument (GI) 4-bit arithmetic logic unit (ALU) slice integrated circuit (IC).

Manufacturer Specifications:

  • Manufacturer: General Instrument (GI)
  • Function: 4-bit ALU slice
  • Technology: TTL (Transistor-Transistor Logic)
  • Package: Typically a 16-pin DIP (Dual In-line Package)
  • Power Supply: Standard TTL voltage levels (5V ±5%)
  • Operating Temperature: Commercial (0°C to +70°C) or Industrial (-40°C to +85°C) depending on variant

Descriptions:

  • The AY-5-8116 is a 4-bit ALU designed for arithmetic and logic operations in digital systems.
  • It can perform addition, subtraction, AND, OR, XOR, and other logical functions.
  • Used in microprocessor-based systems, calculators, and early computing applications.
  • Cascadable for wider word lengths (e.g., 8-bit, 16-bit).

Features:

  • 4-bit parallel processing
  • Carry Look-Ahead (CLA) support for faster arithmetic operations
  • Multiple function selection via control inputs
  • Compatible with standard TTL logic levels
  • Low-power consumption (typical for TTL ICs of the era)

This IC was commonly used in 1970s and early 1980s computing systems before being superseded by more advanced ALUs and microprocessors.
