SN74LV163ADR

The SN74LV163ADR is a high-speed, low-voltage synchronous 4-bit binary counter manufactured by Texas Instruments. It is part of the 74LV family of logic devices, which are designed to operate at lower supply voltages while maintaining high performance. Here’s a detailed description of its features and specifications:

General Features:

• Type: 4-bit binary counter
• Technology: Low-voltage CMOS (Complementary Metal-Oxide-Semiconductor)
• Supply Voltage: Operates typically from 2.0V to 5.5V, making it suitable for battery-powered applications and low-power designs.
• Speed: High-speed operation with a maximum clock frequency of up to 100 MHz at 5V, ensuring fast counting capabilities.
• Synchronous Operation: All counting operations are synchronized to the clock input, allowing for predictable timing and behavior.

Pin Configuration:

The SN74LV163ADR typically comes in a 16-pin TSSOP (Thin Shrink Small Outline Package) or other package types, with the following key pins:

• Clock (CLK): The input pin where the clock signal is applied. The counter increments on the rising edge of the clock.
• Reset (CLR): An active-low input that resets the counter to zero when asserted.
• Load (LOAD): An active-low input that allows loading a preset value into the counter.
• Data Inputs (D0-D3): Four data input pins used for loading a preset value when the LOAD pin is active.
• Count Enable (ENP, ENT): Enable inputs that allow the counter to increment when asserted.
• Output Pins (Q0-Q3): Four output pins that represent the current count value in binary form.

Functional Characteristics:

• Counting Mode: The counter can operate in both up and down counting modes, depending on the configuration of the control inputs.
• Asynchronous Reset: The counter can be reset asynchronously, allowing for immediate control over the counting state.
• Preset Functionality: The ability to load a specific value into the counter makes it versatile for various applications where a specific starting count is required.

Electrical Characteristics:

• Input/Output Voltage Levels: Compatible with TTL logic levels, ensuring interoperability with other logic families.
• Low Power Consumption: Designed for low static and dynamic power consumption, making it ideal for energy-efficient designs.
• High Noise Immunity: The device features high noise margins, ensuring reliable operation in noisy environments.

Applications:

The SN74LV163ADR is widely used in various applications, including:

• Digital clocks and timers
• Frequency dividers
• Event counters
• State machines
• Any application requiring counting or frequency division

Summary:

The SN74LV163ADR from Texas Instruments is a versatile and efficient 4-bit binary counter that combines low voltage operation with high-speed performance. Its synchronous design, combined with features like preset loading and asynchronous reset, makes it suitable for a wide range of digital applications. The device's compact package and low power consumption further enhance its appeal for modern electronic designs.
