DEC-74H55N (SN74H55N)** is a dual 4-wide AND-OR-INVERT (AOI) gate integrated circuit manufactured by Texas Instruments.

The DEC-74H55N (SN74H55N) is a dual 4-wide AND-OR-INVERT (AOI) gate integrated circuit manufactured by Texas Instruments.

Specifications:

  • Logic Type: AND-OR-INVERT (AOI)
  • Number of Gates: 2 (Dual)
  • Number of Inputs per Gate: 4-wide (4-4-3-2 input configuration)
  • Supply Voltage (VCC): 4.75V to 5.25V (Standard 5V operation)
  • Propagation Delay: Typically 10ns (at 5V)
  • Operating Temperature Range: -40°C to +85°C
  • Package Type: PDIP-14 (Plastic Dual In-line Package)
  • Logic Family: 74H (High-speed TTL)

Descriptions:

The SN74H55N is a dual 4-wide AND-OR-INVERT gate that performs the Boolean function (A·B·C·D + E·F·G·H + I·J·K + L·M)' in each gate. It is designed for high-speed digital logic applications and is compatible with standard TTL logic levels.

Features:

  • High-Speed Operation: Optimized for fast switching applications.
  • Wide Operating Voltage: Supports standard 5V TTL logic levels.
  • Dual-Gate Configuration: Two independent AOI gates in a single IC.
  • TTL-Compatible Inputs & Outputs: Ensures compatibility with other TTL logic families.
  • Standard PDIP-14 Package: Easy to use in breadboards and prototyping.

This IC is commonly used in digital systems for logic minimization, arithmetic circuits, and control logic applications.
