74AC16373DLR Logic - Latches by Texas Instruments

The 74AC16373DLR is a specific type of integrated circuit (IC) produced by Texas Instruments, part of the 74AC family of logic devices. This particular IC is a 16-bit transparent latch with a tri-state output, designed for high-speed digital applications. Here’s a detailed description of its features and specifications:

General Features:

• Type: 16-bit transparent latch
• Family: 74AC (Advanced CMOS)
• Package: Typically available in a 48-pin TQFP (Thin Quad Flat Package) or similar surface-mount packages.
• Supply Voltage: Operates typically at a supply voltage of 2V to 6V, making it compatible with a wide range of digital systems.
• Speed: High-speed operation, with propagation delays typically in the range of 3-5 nanoseconds at 5V, depending on the load and conditions.

Functional Description:

• Transparent Latch: The 74AC16373DLR functions as a transparent latch, meaning that when the latch enable (LE) input is high, the output follows the input. When LE goes low, the output holds the last value present at the input.
• Tri-State Outputs: The outputs can be placed in a high-impedance state, allowing multiple devices to share the same output line without interference. This is controlled by the output enable (OE) pin.
• Data Inputs: The device has 16 data inputs (D0 to D15) that can accept signals from other logic devices or microcontrollers.
• Control Inputs: In addition to the LE and OE pins, the IC includes a clock input (CLK) that can be used to synchronize data latching with other components in a digital circuit.

Electrical Characteristics:

• Input/Output Logic Levels: Compatible with standard TTL logic levels, ensuring seamless integration with other digital components.
• Power Consumption: Low power consumption typical of CMOS technology, making it suitable for battery-operated devices.
• Temperature Range: Typically rated for operation from -40°C to +125°C, allowing for use in a variety of environmental conditions.

Applications:

The 74AC16373DLR is commonly used in applications such as:

• Data storage and buffering in digital circuits.
• Temporary data holding in microprocessor and microcontroller systems.
• Implementing state machines and control logic in complex digital systems.
• Communication interfaces where data needs to be latched and transmitted.

Pin Configuration:

The pin configuration of the 74AC16373DLR includes:

• Data Inputs (D0-D15): 16 pins for data input.
• Latch Enable (LE): Controls when the data is latched.
• Output Enable (OE): Controls the tri-state output.
• Clock (CLK): Synchronizes the latching of data.
• Power and Ground Pins: Standard VCC and GND pins for power supply connections.

Conclusion:

The 74AC16373DLR from Texas Instruments is a versatile and efficient component for digital circuit design, providing reliable data latching and tri-state output capabilities. Its high-speed performance and low power consumption make it an ideal choice for modern electronic applications.
