SN74LVTH162373DLR

The SN74LVTH162373DLR is a high-speed, low-voltage, 16-bit transparent latch designed by Texas Instruments. It is part of the LVTH (Low-Voltage Transceiver with High-Speed) family, which is optimized for use in high-performance digital circuits. Here’s a detailed description of its features and specifications:

General Features:

• Functionality: The SN74LVTH162373DLR operates as a transparent latch, meaning that data is passed through to the output when the latch enable (LE) signal is active. When LE is low, the last data present at the input is held at the output.
• Bit Configuration: It has 16 bits, allowing it to handle wide data paths efficiently.
• Data Inputs and Outputs: The device features 16 data inputs (D0-D15) and 16 corresponding outputs (Q0-Q15), enabling simultaneous data handling.

Electrical Characteristics:

• Supply Voltage: It operates with a supply voltage range of 2.7V to 3.6V, making it suitable for low-voltage applications.
• Input and Output Voltage Levels: The device is compatible with TTL (Transistor-Transistor Logic) levels, ensuring it can interface with a variety of logic families.
• Propagation Delay: The typical propagation delay from the input to the output is very low, typically around 3.5 ns at 3.3V, which is ideal for high-speed applications.

Package and Pin Configuration:

• Package Type: The SN74LVTH162373DLR is available in a TSSOP (Thin Shrink Small Outline Package) with a 48-pin configuration, which is compact and suitable for space-constrained designs.
• Pin Count: The 48 pins include power and ground pins, data inputs, outputs, and control signals such as LE (Latch Enable) and OE (Output Enable).

Control Signals:

• Latch Enable (LE): This control signal determines when the data is latched. When LE is high, the outputs follow the inputs. When LE goes low, the outputs retain the last input state.
• Output Enable (OE): This signal controls the output state. When OE is low, the outputs are enabled and reflect the latched data. When OE is high, the outputs are in a high-impedance state, effectively disconnecting them from the circuit.

Applications:

The SN74LVTH162373DLR is suitable for a variety of applications, including:

• Data buffering and storage in digital systems.
• High-speed data communication interfaces.
• Temporary data holding in microcontroller and FPGA designs.
• Any application requiring low-voltage, high-speed data latching.

Additional Features:

• Low Power Consumption: The device is designed to consume minimal power, making it suitable for battery-operated devices.
• High Noise Immunity: The LVTH family provides robust performance in noisy environments, ensuring reliable operation.

Conclusion:

The SN74LVTH162373DLR from Texas Instruments is a versatile and efficient 16-bit transparent latch that meets the demands of modern digital circuits. Its combination of low voltage operation, high-speed performance, and compact packaging makes it an excellent choice for a wide range of electronic applications.
