The NXP 74LVC841AD is a high-performance, octal D-type transparent latch that is designed to meet the requirements of high-speed memory buffering and data storage. This integrated circuit is part of the LVC family, which signifies its Low-Voltage CMOS technology, ensuring that it operates at a lower voltage with reduced power consumption while still delivering fast performance.

Key Features:

• Wide Operating Voltage Range: The device is compatible with a voltage range of 1.2V to 3.6V, which allows for flexible integration into various system voltage levels.
• High-Speed Operation: With a typical propagation delay of only 3.7ns at a 3.3V supply, the 74LVC841AD is ideal for high-speed applications that require quick data transfer and storage.
• Low Power Consumption: The low power consumption is a hallmark of the LVC series, making this device suitable for battery-powered and energy-sensitive applications.
• Octal Configuration: The device contains eight latches, which can be used to store eight bits of data each, providing significant storage capacity in a compact form factor.
• Transparent Latch Feature: The transparent nature of the latches means that when the latch enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the data that was present at the D inputs at the time the transition occurred is stored in the latch.
• 5V Tolerant Inputs: Inputs can tolerate 5V signals, allowing for interface with higher voltage logic levels without the need for external voltage level shifters.
• Bus-Hold Circuitry: This feature prevents floating inputs and eliminates the need for external pull-up or pull-down resistors.
• Output Drive Capability: Capable of driving 50 Ohm transmission lines, which is useful for backplane driving or interfacing with other high-capacity loads.

Applications:

The 74LVC841AD is suitable for a wide range of applications including, but not limited to, memory buffer registers, data storage and retrieval systems, and as an interface between mismatched bus speeds. Its high-speed and low-power characteristics make it particularly well-suited for portable and power-sensitive devices.
