Description:

The SN74AS533N is an octal transparent latch with 3-state outputs, designed for bus-oriented applications. It allows data to be latched when the enable (LE) signal is active and provides high-impedance outputs when the output enable (OE) signal is inactive.

Features:

• High-Speed Operation: Optimized for fast switching (AS family)
• 3-State Outputs: Supports bus sharing and reduces loading
• Wide Operating Voltage: Compatible with standard TTL levels
• High Drive Capability: Suitable for driving bus lines
• Latch Enable (LE) Control: Transparent data transfer when enabled

This device is commonly used in data storage, buffering, and bus interface applications.
