The SN74ALS29821DW is a 10-bit edge-triggered D-type flip-flop designed for driving capacitive loads with tri-state outputs. It features buffered control inputs to minimize DC loading effects and can operate in a high-impedance state during power-up and power-down, ensuring that outputs do not significantly load the bus lines. The device is characterized for operation from 0¬8C to 70¬8C and requires a supply voltage between 4.75V and 5.25V. It supports a maximum output current of 24mA for high-level outputs and 48mA for low-level outputs. The flip-flop is suitable for applications such as buffer registers, I/O ports, and bidirectional bus drivers with parity. The package type is a 24-SOIC, making it suitable for surface mount applications.
