Rochester Electronics SN74HC174DG4 Environmental and export classification status description

The Texas Instruments SN74HC174DG4 is an integrated circuit (IC) that belongs to the 74HC series of high-speed CMOS logic devices. It is a hex positive-edge-triggered D-type flip-flop with clear. The IC contains six flip-flops, each with a data input (D), a clock input (CLK), a set input (S), a clear input (CLR)/2, and complementary outputs (Q and Q\). Functions: 1. Flip-Flop Operation: The SN74HC174DG4 functions as a D-type flip-flop, storing one bit of data (either high or low) that can be latched onto its output upon the rising edge of the clock signal. 2. Clear Functionality: It includes a clear input that resets the flip-flop outputs to a known state when activated. 3. Wide Operating Voltage Range: This IC operates from 2V to 6V supply voltage. Applications: - Digital Data Storage: Used to store and hold binary information in digital systems. - Clock and Data Synchronization: Ideal for clock and data synchronization in various applications. - State Register: Can be used as a state or buffer register in digital systems. - Signal Processing: Employed in signal processing, control systems, and logic circuits. Alternative Components: - 74LS174: Low-power Schottky version of the hex D flip-flop with clear. - 74HCT174: High-speed CMOS version with TTL-compatible inputs and outputs. - CD74HC174: A similarly functioning hex D flip-flop from Texas Instruments. Embedded Modules: - Flip-flop modules in FPGA: FPGA designs often contain flip-flop modules that can be configured as D flip-flops. - Microcontroller Units (MCUs): Some MCUs feature built-in flip-flop functionality suitable for various applications. - Application-Specific Integrated Circuits (ASICs): Custom ASIC designs may integrate flip-flop functionality tailored to specific requirements.
