74LS147 DIP 10-Line To 4-Line Priority Encoder IC

Product Overview: 74LS147 DIP 10-Line to 4-Line Priority Encoder

The 74LS147 is a 10-line to 4-line priority encoder integrated circuit (IC) that converts ten binary inputs into a four-line binary output. This IC is designed to encode the highest-priority active input line into a binary code, making it essential for applications that require prioritization of input signals.

Key Specifications:

• Type: 10-Line to 4-Line Priority Encoder
• Package: DIP-16 (Dual In-line Package)
• Supply Voltage (Vcc):
  • Minimum: 4.75V
  • Typical: 5V
  • Maximum: 5.25V
• Operating Temperature Range: -55°C to +125°C
• Power Dissipation: Approximately 32 mW
• Output Current Capability: Can sink up to 8 mA per output
• Propagation Delay: Typically around 21 ns

Pin Configuration:

Features:

• Priority Encoding: The encoder identifies the highest-priority active input and provides a binary output corresponding to that input.
• Active-Low Outputs: The outputs are active-low, meaning they are inverted; this allows easy interfacing with other TTL logic devices.
• Cascading Capability: Multiple encoders can be cascaded to handle more than ten inputs.
• Parallel Data Inputs: Allows parallel data input for efficient encoding.

Applications:

The 74LS147 IC is commonly used in:

• Interrupt Handling: Prioritizing interrupt requests in microcontroller applications.
• Data Encoding: Encoding outputs from devices like flash analog-to-digital converters.
• Control Systems: Used in systems requiring signal prioritization and processing.
