The PI74ALVCH16373A is a 16-bit transparent latch with 3-state outputs, manufactured by Pericom (now Diodes Incorporated). It is designed for high-speed, low-power applications and is part of the ALVCH family, which emphasizes advanced low voltage CMOS technology with high-speed capabilities. This makes it well-suited for systems requiring efficient performance at lower voltages.

Applications

• Data buffering
• Memory address latching
• High-speed data acquisition systems
• Bus interface applications
• Clock enables latching

Features

• 16-bit transparent latch
• 3-state outputs
• Low voltage operation (typically 3.3V)
• High-speed data transfer
• Low power consumption
• TTL-compatible inputs
• Transparent or latching mode selectable

Benefits

• Improved system performance with high-speed data transfer
• Reduced power consumption, making it suitable for portable devices
• Flexible data handling with transparent and latching modes
• Simplified integration with TTL-compatible inputs
• Reduced bus loading with 3-state outputs
• Provides data storage during clock transitions

Additional Details

The PI74ALVCH16373A operates from a supply voltage of 2.3V to 3.6V. It has a propagation delay of approximately 3 ns, enabling high-frequency operation. The device can operate in either transparent mode, where the output follows the input when the latch enable (LE) is high, or in latching mode, where the output retains the data present at the input when LE transitions from high to low. The 3-state outputs allow for disconnection from the bus, preventing bus contention. The operating temperature range typically spans from -40°C to +85°C. The device is available in TSSOP and other similar surface-mount packages.
