The SN74LVC821ADW from Texas Instruments is a high-performance, 10-bit flip-flop with a clear function, designed to operate in a wide voltage range from 1.65V to 3.6V. This integrated circuit (IC) is part of the SN74LVC family, which is known for its low-voltage operation and low power consumption, making it ideal for battery-operated and portable applications.

Key Features

• Voltage Range: Operates from 1.65V to 3.6V, providing compatibility with a variety of logic levels and making it suitable for interfacing with both 3.3V and 1.8V logic devices.
• High-Speed Operation: With a typical t<sub>pd of 3.9 ns at 3.3V, the device supports high-speed data transfer, which is crucial for modern digital applications.
• IOFF Support: The IOFF circuitry provides partial Power-down mode operation by disabling the outputs, preventing damaging current backflow through the device when it is powered down.
• Drive Capability: The SN74LVC821ADW can drive up to 24 mA, allowing for direct drive of LEDs and other devices with moderate current requirements.
• Bus Hold: The device features bus hold on data inputs, eliminating the need for external pull-up or pull-down resistors and ensuring the inputs remain at a last known state without floating.
