Product Overview: 74LV373D from NXP

The 74LV373D is a high-performance, low-voltage Octal D-type transparent latch with 3-state outputs, designed and manufactured by NXP Semiconductors. This integrated circuit is part of the 74LV family, which operates on a low-power voltage range, making it ideal for use in battery-operated devices, portable electronics, and other applications where power conservation is critical.

This latch is designed to store the data presented on its D inputs whenever the Latch Enable (LE) input is HIGH, providing a seamless interface between asynchronous and synchronous system components. The data on the D inputs that meet the setup and hold time requirements on the LE input are transferred to the Q outputs. When the LE input is LOW, the Q outputs remain at their previous levels, effectively storing the latched data.

Key Features:

• Logic Family: The device is part of the 74LV logic family, known for its low-voltage operation and compatibility with TTL levels.
• Supply Voltage Range: The 74LV373D operates on a wide supply voltage range from 2.0 V to 5.5 V, providing design flexibility for various applications.
• Octal Latch: The device features eight latches, which can be controlled simultaneously, providing an efficient solution for data storage and transfer.
• 3-State Outputs: The outputs can be placed in a high-impedance state, allowing for bus-oriented applications and easy connection to system buses without the need for external drivers.
• Low Power Consumption: It has a low power consumption profile, which is critical for power-sensitive designs.
