The PI74FCT162373TVA is a 16-bit transparent latch from Pericom Semiconductor (now Diodes Incorporated) belonging to the FCT (Fast CMOS Technology) logic family. This device is designed for high-speed performance and low power consumption, making it suitable for various applications requiring temporary data storage and buffering.

Applications

• Data buffering in memory systems
• Address latching in microprocessor systems
• I/O port expansion
• Pipeline registers in digital signal processing
• Data multiplexing and demultiplexing

Features

• 16-bit transparent latch
• TTL-compatible inputs
• High-speed operation
• Low power consumption
• 3-state outputs for bus interfacing
• Enable (EN) input for latch control

Benefits

• Improved system performance due to fast propagation delay
• Easy interfacing with TTL logic levels
• Reduced power consumption for increased energy efficiency
• Flexible bus interfacing with 3-state outputs
• Simple latch control with the EN input

Additional Details

The PI74FCT162373TVA features 16 D-type latches with a transparent mode. When the Enable (EN) input is high, the Q outputs follow the data at the D inputs. When EN transitions low, the data present at the D inputs is latched and held at the Q outputs. The 3-state outputs allow the device to be connected to a bus without loading it when the outputs are disabled. The device is designed to operate from a 5V power supply and is available in various surface-mount packages, such as TSSOP, making it suitable for high-density board designs.
