Description

M74HCT574RM13TR High-Speed CMOS D-Type Flip-Flop with Clear

The M74HCT574RM13TR from STMicroelectronics is a high-speed CMOS D-type flip-flop with clear. It is designed for use in a variety of electronic applications, including clock dividers, counters, and data registers.

The M74HCT574RM13TR has four D-type flip-flops, each with its own set of clock and clear inputs. The D input of each flip-flop is sampled on the rising edge of the clock input. If the clear input is asserted, the flip-flop will be reset to the low state.

The M74HCT574RM13TR is a high-speed device, with a typical clock frequency of 100 MHz. It is also a low-power device, with a typical supply current of 10 mA.

Features

High speed: 100 MHz typical clock frequency
Low power: 10 mA typical supply current
Wide operating voltage range: 2 V to 6 V
TTL compatible inputs and outputs
Schmitt trigger inputs for noise immunity
ESD protection: 2000 V HBM

Applications

Clock dividers
Counters
Data registers
Shift registers
Frequency synthesizers
Test and measurement equipment
Industrial control systems
Automotive electronics
