SN74AHC273N Octal D-Type Flip-Flop with Clear

The SN74AHC273N is a high-performance, octal D-type flip-flop integrated circuit (IC) from Texas Instruments, designed for use in a wide range of digital applications. This particular device features eight edge-triggered D-type flip-flops with clear functionality, all housed within a robust 20-pin PDIP (Plastic Dual-In-line Package).

The SN74AHC273N is part of the 'AHC' family of logic devices, which means it operates with advanced high-speed CMOS technology. This technology ensures the device has a balanced trade-off between speed and power consumption, making it ideal for battery-operated and power-sensitive applications.

Each flip-flop in the SN74AHC273N has an independent D (data) input, CLK (clock) input, and CLR (clear) input. The clear input is active low, which means that holding it in a low state will reset all flip-flops, regardless of the clock input, ensuring a clear and defined start-up state for the system. The clock input is responsible for data transfer, with the flip-flop capturing the state of the D input on the rising edge of the clock signal. The output from each flip-flop is available on separate Q outputs.

With its wide operating voltage range of 2V to 5.5V, the SN74AHC273N provides great flexibility in interfacing with different logic levels, which is particularly useful in mixed-voltage systems. Additionally, the IC offers a high noise immunity and low power consumption, with a typical t<sub>pd (propagation delay time) of 8.5 ns at 5V, allowing for high-speed operation without sacrificing power efficiency.

This device is characterized for operation from -40°C to 85°C, making it reliable in various environmental conditions. The SN74AHC273N is RoHS compliant and is designed to meet the stringent requirements of the latest industrial and consumer electronic standards.

Whether you're designing digital circuits for data storage, communication systems, or need a reliable flip-flop for your microcontroller projects, the SN74AHC273N from Texas Instruments offers a dependable and versatile solution for your digital logic needs.
