The PI74ALVCH16821AX is a 10-bit bus interface D-type flip-flop with 3-state outputs manufactured by Pericom (now Diodes Incorporated). It is designed for high-speed, low-power applications. It is part of the ALVCH (Advanced Low Voltage CMOS with High-Speed) family and is suitable for systems requiring high performance while operating at low voltages.

Applications

• Bus interface
• Register files
• Memory address registers
• Pipeline registers
• Data storage

Features

• 3-state outputs
• Low voltage operation (typically 3.3V)
• High-speed data transfer
• Low power consumption
• TTL-compatible inputs
• Positive-edge triggered clock

Benefits

• Provides reliable data storage with D-type flip-flops

Additional Details

The PI74ALVCH16821AX operates from a supply voltage of 2.3V to 3.6V. It features a typical propagation delay of around 3ns, which enables high-frequency operation. The 3-state outputs allow the device to be effectively disconnected from the bus when not in use, preventing bus contention. The positive-edge triggered clock ensures data is captured only on the rising edge of the clock signal. The operating temperature range is typically -40°C to +85°C. It's available in TSSOP and other surface mount packages.
