• 22 Input Pins and 10 Output Macrocells
• Programmable Output Polarity
• Output Logic Macrocells (OLMCs) for flexible output configuration
• Security Cell for design protection
• Available in various package options, including PLCC and DIP
• Low Power consumption

Benefits

• Reduced system cost through the integration of multiple logic functions into a single device.
• Faster time-to-market due to rapid prototyping and design iteration capabilities.
• Increased design flexibility by allowing reconfiguration for different applications.
• Improved system reliability with the use of CMOS technology.
• Simplified inventory management by replacing multiple PAL/GAL devices with a single GAL22V10B-15LJI.
• Lower power consumption, making it suitable for portable and battery-powered applications.

Additional Details

The GAL22V10B-15LJI operates on a 5V power supply and features programmable output polarity, which allows each output to be configured as active-high or active-low. The output logic macrocells (OLMCs) enhance design flexibility by allowing individual configuration of each output. A security cell is included to prevent unauthorized code reading and copying. This device is available in several package options, including PLCC and DIP, to accommodate different mounting requirements. The 15ns propagation delay ensures it is suitable for high-speed applications. The low-power characteristics are particularly beneficial in applications where energy efficiency is critical.
