SN74HC132D

The SN74HC132D is a quad 2-input NAND gate integrated circuit (IC) manufactured by Texas Instruments. It belongs to the 74HC (High-speed CMOS) family, which is known for its high-speed operation and low power consumption. Here’s a detailed description of the SN74HC132D:

Package and Pin Configuration

• Package Type: The SN74HC132D is typically available in a 14-pin Dual In-line Package (DIP) or a surface-mount package (SOIC). The DIP version is often used for prototyping and breadboarding, while the SOIC version is more suitable for compact PCB designs.
• Pin Count: 14 pins, with each pin serving a specific function.
• Pin Layout: The pins are arranged in two rows, with the following key functions:
  • Inputs: Each of the four NAND gates has two inputs (A and B).
  • Outputs: Each gate has a corresponding output (Y).
  • Power Supply Pins: The IC requires a VCC pin for the positive supply voltage and a GND pin for the ground connection.

Electrical Characteristics

• Supply Voltage (VCC): The SN74HC132D operates over a wide supply voltage range, typically from 2V to 6V, making it versatile for various applications.
• Input Voltage Levels: The input voltage levels are compatible with standard TTL logic levels, allowing it to interface with other logic families.
• Output Drive Capability: The outputs can drive standard TTL loads, providing a high output current capability, which is essential for driving other logic gates or loads.

Logic Functionality

• NAND Gate Function: Each of the four gates performs a NAND operation, which means the output is LOW only when both inputs are HIGH. The truth table for a 2-input NAND gate is as follows:
  • A = 0, B = 0 → Y = 1
  • A = 0, B = 1 → Y = 1
  • A = 1, B = 0 → Y = 1
  • A = 1, B = 1 → Y = 0
• Propagation Delay: The SN74HC132D features a fast propagation delay, typically in the range of nanoseconds, allowing for high-speed digital circuit applications.
