SN74LVC373ADBR

The SN74LVC373ADBR is a high-speed, low-voltage octal transparent latch designed by Texas Instruments. It is part of the LVC family of logic devices, which are known for their low power consumption and high-speed performance. Here’s a detailed description of its features and specifications:

General Description:

• Functionality: The SN74LVC373ADBR is an octal transparent latch, meaning it can hold and store data when enabled. It allows data to pass through when the latch is in a transparent state, and it holds the data when the latch is disabled.
• Data Inputs: It has eight data inputs (D0 to D7) that can accept both high and low logic levels.
• Control Inputs: The device features a latch enable (LE) input that controls the transparency of the latch. When LE is high, the data present at the inputs is passed to the outputs. When LE is low, the outputs retain the last data state.
• Output Configuration: The outputs (Q0 to Q7) are inverting, meaning that they output the opposite logic level of the corresponding data input when the latch is enabled.

Electrical Characteristics:

• Supply Voltage: The device operates with a supply voltage range of 1.65V to 5.5V, making it suitable for low-voltage applications.
• Input Voltage Levels: The input high voltage (VIH) and input low voltage (VIL) levels are compatible with various logic families, ensuring interoperability with other devices.
• Output Drive Capability: The outputs can drive up to 24 mA, allowing for direct connection to other logic devices or loads.

Package Information:

• Package Type: The SN74LVC373ADBR is available in a small, surface-mount SOIC (Small Outline Integrated Circuit) package, which is ideal for space-constrained applications.
• Pin Count: It has 20 pins, with a specific pin configuration for power, ground, data inputs, control inputs, and outputs.

Performance:

• Propagation Delay: The device features low propagation delays, typically in the range of a few nanoseconds, which makes it suitable for high-speed applications.
• Power Consumption: The SN74LVC373ADBR is designed for low power consumption, making it ideal for battery-operated devices and energy-efficient designs.

Applications:

• The SN74LVC373ADBR is commonly used in various applications, including:
  • Data storage and buffering in digital circuits.
  • Temporary data holding in microcontroller and FPGA designs.
  • Interface applications where data needs to be latched and controlled.

Additional Features:

• Thermal Protection: The device includes thermal protection features to prevent damage from overheating.
• ESD Protection: It is designed with electrostatic discharge (ESD) protection to ensure reliability in various environments.

In summary, the SN74LVC373ADBR from Texas Instruments is a versatile and efficient octal transparent latch suitable for a wide range of digital applications, characterized by its low voltage operation, high-speed performance, and compact packaging.
