The SN74ALVCH16373DGGR is a specific part number for a 16-bit transparent D-type latch with 3-state outputs, also known as a latch/register IC (Integrated Circuit), manufactured by Texas Instruments. This IC is part of the ALVCH (Advanced Low-Voltage CMOS with 3.6-V Tolerant Inputs and Outputs) logic family, designed for digital logic applications where data storage and signal sharing are required.
Key Features:
- 16-Bit Latch: The IC typically includes sixteen D-type transparent latches, each with a data input (D), a data output (Q), and control inputs (such as clock and enable).
- Transparent Latch: It is a transparent latch, meaning that when the latch enable (LE) input is high, the Q outputs follow the data inputs (D). When LE is low, the outputs hold their previous state.
- 3.6-V Tolerant Inputs and Outputs: This IC is designed to be tolerant of 3.6V voltage levels on its inputs and outputs, which makes it suitable for mixed-voltage level applications.
- Low-Voltage Operation: The ALVCH logic family operates at low supply voltages, typically from 1.65V to 3.6V, making it suitable for low-power and battery-powered applications.
- 3-State Outputs: It provides 3-state outputs, allowing you to control whether the latch outputs are actively driving signals or in a high-impedance state. This feature is essential for bus sharing.
Applications:
The SN74ALVCH16373DGGR and similar transparent latch ICs are used in various digital logic applications, including:
- Data Storage: They are used to store and latch data, allowing it to be temporarily held and then released when needed.
- Control Logic: Transparent latches can be used in control logic circuits where data needs to be captured and held until a specific condition is met.
- Data Transfer: These ICs can be used for data transfer applications, such as parallel-to-serial conversion or vice versa.
- Register Stages: They can serve as register stages in microprocessors, microcontrollers, or digital signal processors.
- Level Shifting: In mixed-voltage systems, transparent latches can be used for level shifting tasks.
- Bus Sharing: The 3-state outputs allow multiple latches to share a common bus without causing bus contention.
