SN74HC4040PWRG4

The SN74HC4040PWRG4 is a high-speed CMOS binary ripple counter produced by Texas Instruments. It is part of the 74HC family, which is known for its high-speed performance and low power consumption. Here’s a detailed description of its features and specifications:

General Description:

The SN74HC4040 is a 12-stage binary ripple counter that can count in binary from 0 to 4095 (2^12 - 1). It is designed to operate with a wide range of supply voltages, making it suitable for various digital applications. The device is housed in a 16-pin TSSOP (Thin Shrink Small Outline Package) form factor, which allows for compact designs in printed circuit boards (PCBs).

Key Features:

• Counting Range: The counter can count from 0 to 4095, providing a 12-bit binary output.
• Ripple Counter: It operates as a ripple counter, meaning that each flip-flop in the counter toggles based on the output of the previous flip-flop, allowing for a simple cascading design.
• High-Speed Operation: The device can operate at high frequencies, making it suitable for applications requiring fast counting.
• Low Power Consumption: The CMOS technology used in the SN74HC4040 ensures low static and dynamic power consumption, which is beneficial for battery-operated devices.
• Wide Supply Voltage Range: It can operate with a supply voltage ranging from 2V to 6V, providing flexibility in design.
• Asynchronous Reset: The counter features an asynchronous reset input, allowing for immediate resetting of the count to zero regardless of the clock state.
• Output Compatibility: The outputs are compatible with standard TTL levels, making it easy to interface with other digital logic devices.

Pin Configuration:

The SN74HC4040PWRG4 has 16 pins, which include:

• Clock Input (CLK): The clock signal that drives the counting operation.
• Reset Input (RESET): An active-low input that resets the counter to zero.
• Output Pins (Q0 to Q11): These pins provide the binary output of the counter, representing the current count value.
• VCC and GND: Power supply and ground pins for the device.

Applications:

The SN74HC4040PWRG4 is commonly used in various applications, including:

• Frequency dividers
• Digital clocks
• Event counters
• Timer circuits
• Frequency synthesizers

Package Information:

• Package Type: TSSOP (Thin Shrink Small Outline Package)
• Pin Count: 16
• Dimensions: The TSSOP package is compact, making it suitable for space-constrained applications.

Conclusion:

The SN74HC4040PWRG4 from Texas Instruments is a versatile and efficient binary ripple counter that is ideal for a wide range of digital counting applications. Its combination of high-speed performance, low power consumption, and flexible voltage operation makes it a popular choice among engineers and designers in the field of electronics.
