SN74LVC373APWR

The SN74LVC373APWR 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 SN74LVC373APWR is an octal transparent latch, meaning it can hold and store data when enabled. When the latch is enabled, the output reflects the input state. When the latch is disabled, the output retains the last state.
• Data Inputs: It has eight data inputs (D0 to D7) that accept standard logic levels.
• Control Inputs: The device features a latch enable (LE) input that controls the transparency of the latch. When LE is high, the outputs follow the inputs. When LE is low, the outputs hold the last input state.
• Output Enable: The output enable (OE) input allows for the outputs to be disabled, providing a high-impedance state for bus-oriented applications.

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 threshold levels are compatible with both TTL and CMOS logic levels, allowing for versatile interfacing.
• Propagation Delay: The typical propagation delay from input to output is very low, typically around 3.5 ns at 3.3V, ensuring fast data processing.
• Power Consumption: The device is designed for low power consumption, with a typical supply current of only a few microamperes, making it ideal for battery-operated devices.

Package Information:

• Package Type: The SN74LVC373APWR is available in a TSSOP (Thin Shrink Small Outline Package) with 20 pins, which is compact and suitable for space-constrained applications.
• Thermal Characteristics: The package is designed to dissipate heat efficiently, with a maximum junction temperature rating of 150°C.

Applications:

The SN74LVC373APWR is widely used in various applications, including:

• Data storage and buffering in digital circuits.
• Interface applications where data needs to be latched and held.
• Bus-oriented systems where multiple devices share a common data line.
• Consumer electronics, automotive systems, and industrial automation.

Summary:

The SN74LVC373APWR from Texas Instruments is a versatile and efficient octal transparent latch that combines high-speed performance with low power consumption. Its compatibility with a wide range of logic levels and its compact package make it an excellent choice for modern digital applications.
