Nexperia 74HC574D,652 Octal D Type Flip Flop IC, 3-State, 20-Pin SOIC
Product Details
74HC Family Flip-Flops & Latches, Nexperia
A range of NXP Flip-Flops and Latches from the 74HC Family of CMOS Logic ICs. The 74HC Family use silicon gate CMOS technology to achieve operating speeds similar to the LSTTL family but with the low power consumption of standard CMOS integrated circuits.
High-Speed CMOS Logic
Operating Voltage: 2 to 6 V
Compatibility: Input CMOS, Output CMOS
The 74HC574, 74HCT574 is an 8-bit positive-edge triggered D-type flip-flop with 3-state outputs. The device features a clock (CP) and output enable (OE) inputs. The flip-flops will store the state of their individual D-inputs that meet the set-up and hold time requirements on the LOW-to-HIGH clock (CP) transition. A HIGH on OE causes the outputs to assume a high-impedance OFF-state. Operation of the OE input does not affect the state of the flip-flops. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
Mixed 5 V and 3.3 V applications
Improved signal integrity with integrated termination resistors
High noise immunity
Flow through pin out for easy layout
Wide supply voltage range
Low propagation delay
Overvoltage tolerant input options
Integrated source termination resistor options
Bus hold options
Key applications
Frequency division
Controlled delays
Interface between asynchronous and synchronous systems
