AL422B

The AL422B is a FIFO (First-In, First-Out) memory buffer IC designed for video and digital signal processing. It features:
- 384K × 8-bit (3 Mbit) memory capacity
- Up to 50 MHz operation (supports high-speed data streaming)
- Separate read/write clocks for asynchronous operation
- Standard 5V supply voltage
Commonly used in video delay lines, CCD signal processing, and data buffering, the AL422B ensures smooth data flow between mismatched speed systems. Its simple interface (8-bit parallel I/O) and low standby current make it suitable for embedded applications.
For detailed specs, refer to the datasheet from the manufacturer (Alliance Memory or similar).
