The TC74HCT573P is an octal D-type transparent latch with three-state outputs manufactured by Toshiba Semiconductor and Storage. This device is designed for high-speed operation and is compatible with TTL logic levels, making it suitable for interfacing with both TTL and CMOS systems. The latch features an Output Enable (OE) input, which, when high, places the outputs in a high-impedance state, allowing for easy busing.

Applications

• Data Buffering
• Address Latching
• Memory Interfacing
• Microprocessor Systems
• Peripheral Interfacing

Features

• High Speed Operation: tpd = 18 ns (typ.) at VCC = 5 V
• TTL Input Compatibility
• Three-State Outputs
• Octal Configuration
• Transparent Latch Operation
• Wide Operating Voltage Range: VCC = 4.5 V to 5.5 V

Benefits

• Efficient data buffering and latching for various applications.
• Easy interfacing with TTL logic, simplifying system design.
• Three-state outputs allow for easy busing and prevent loading.
• Suitable for applications requiring 8-bit data handling.
• Transparent latch operation simplifies data transfer.
• Wide operating voltage range provides design flexibility.

The TC74HCT573P is packaged in a DIP-20. The operating temperature range is from -40°C to +85°C. It is commonly used in applications requiring temporary data storage or buffering, such as in memory interfaces or microprocessor systems.
