STMicroelectronics M74HC73TTR Environmental and export classification status description

The M74HC73TTR is a dual negative edge-triggered JK flip-flop integrated circuit (IC) from STMicroelectronics. It belongs to the 74HC series of high-speed CMOS logic ICs, providing a reliable and well-known solution for digital circuit design. Functions: - The M74HC73TTR features two independent JK flip-flop units, each with J, K, CLK (clock), and asynchronous preset (PRE) and clear (CLR) inputs. - These flip-flops are negative edge-triggered, meaning they respond to changes at their inputs during the falling edge of the clock signal. - The IC also includes complementary outputs (Q and /Q) for each flip-flop, providing the user with the ability to implement various logic functions. Applications: - Due to its dual flip-flop configuration and versatility, the M74HC73TTR is commonly used in digital systems for tasks such as timing, frequency division, counting, and state storage. - It can be found in applications like counters, registers, shift registers, sequence generators, and clock divider circuits. Alternative Components: - Alternative ICs that can be used as replacements for the M74HC73TTR include the 74HC109, 74HC174, and 74HC373, which offer similar functionalities in terms of flip-flops and logic gates. Embedded Modules: - The M74HC73TTR is a standalone IC and does not typically come with embedded modules. However, it can be integrated into larger digital circuits alongside other components such as microcontrollers, memory modules, and interface ICs. Related Q&A: 1. What is the difference between positive edge-triggered and negative edge-triggered flip-flops? - Positive edge-triggered flip-flops respond to input changes at the rising edge of the clock signal, while negative edge-triggered flip-flops react to changes at the falling edge. 2. How do JK flip-flops differ from D flip-flops in terms of functionality? - JK flip-flops offer the ability to toggle their output state when both J and K inputs are high, providing more functionality compared to D flip-flops that only capture and hold data. 3. Can the M74HC73TTR be cascaded to create longer shift registers or counters? - Yes, multiple M74HC73TTR ICs can be cascaded by connecting the outputs of one flip-flop to the inputs of another, allowing for the creation of larger shift registers or counters. 4. What is the purpose of the asynchronous preset and clear inputs on the M74HC73TTR? - The preset and clear inputs allow the user to set the flip-flop to a specific state (either 0 or 1) regardless of the clock signal, enabling initialization or forced output conditions. 5. How does the M74HC73TTR contribute to reducing power consumption in digital circuits? - The high-speed CMOS technology used in the M74HC73TTR helps minimize power consumption by offering low power dissipation and efficient operation, making it suitable for battery-powered devices and energy-efficient designs.
