The SN74HC193D is a high-speed, synchronous 4-bit binary counter manufactured by Texas Instruments. It is part of the 74HC family of logic devices, which are known for their high-speed performance and low power consumption. Here’s a detailed description of its features and specifications:
General Features:
- Type: 4-bit synchronous binary counter
- Technology: High-speed CMOS (Complementary Metal-Oxide-Semiconductor)
- Package: Typically available in a 16-pin Dual In-line Package (DIP) or surface-mount options like TSSOP (Thin Shrink Small Outline Package).
- Supply Voltage: Operates typically between 2V to 6V, making it compatible with a wide range of digital circuits.
- Power Consumption: Low static and dynamic power consumption, suitable for battery-operated devices.
Functional Description:
- Counting Modes: The SN74HC193D can operate in various counting modes, including up, down, and up/down counting, controlled by the mode select inputs.
- Synchronous Operation: All counting operations are synchronized to a common clock input, which allows for predictable timing and easier integration into larger digital systems.
- Reset Functionality: The counter can be asynchronously reset to zero, allowing for easy initialization of the counting sequence.
- Output: The counter provides four output lines (Q0 to Q3) that represent the current count in binary form. These outputs are in a high-impedance state when the counter is disabled.
Pin Configuration:
- Inputs: Includes clock (CLK), reset (RESET), mode select (UP/DOWN), and enable (EN) inputs.
- Outputs: Four output pins (Q0 to Q3) that display the current count.
- Control Pins: Additional control pins for enabling/disabling the counter and selecting the counting direction.
Electrical Characteristics:
- Propagation Delay: Fast propagation delay, typically in the range of nanoseconds, allowing for high-speed counting applications.
- Input/Output Voltage Levels: Compatible with standard TTL (Transistor-Transistor Logic) levels, ensuring interoperability with other logic families.
- Temperature Range: Designed to operate in a wide temperature range, typically from -40°C to +125°C, making it suitable for industrial applications.
Applications:
- Digital Counters: Used in digital clocks, frequency counters, and event counters.
- Frequency Division: Can be used in frequency division applications where counting pulses is required.
- State Machines: Useful in designing state machines where counting states is necessary.
Summary:
The SN74HC193D is a versatile and efficient 4-bit synchronous binary counter that offers high-speed performance and low power consumption. Its ability to operate in various counting modes, combined with its synchronous design, makes it an ideal choice for a wide range of digital applications. Whether used in consumer electronics, industrial controls, or educational projects, the SN74HC193D provides reliable and accurate counting capabilities.
