What are the key features of CD74HC574M96G4?

  • 8-bit octal D-type flip-flop with positive edge-triggered clocking and active-low output enable for 3-state bus driving
  • High-speed CMOS HC/UH family operation up to 20 MHz with 50 pF load capacitance across a 2 V to 6 V supply range
  • 20-pin SOIC package with 7.8 mA output sink current enabling reliable bus interface buffering in digital logic designs

What is CD74HC574M96G4 used for?

The CD74HC574M96G4 is used as an 8-bit data bus register and output latch in microprocessor and FPGA systems where data must be captured on a clock edge and held stable for downstream logic. Its 3-state output enable allows multiple devices to share a common 8-bit bus without contention. Typical applications include address latches in memory interfaces, I/O port expansion for embedded controllers, and data pipeline buffering in industrial logic boards.

Frequently Asked Questions

What output drive current does the CD74HC574M96G4 provide and how many bus loads can it drive at 50 pF?

The CD74HC574M96G4 provides a maximum output sink current of 7.8 mA per pin with a specified load capacitance of 50 pF. At this drive strength and 5 V supply, it can reliably buffer up to 8 parallel data lines simultaneously, making it suitable for latching microprocessor data buses in systems with moderate PCB trace capacitance between 20 pF and 50 pF per line.

How does the active-low output enable of the CD74HC574M96G4 simplify multi-device bus sharing?

The active-low OE pin places all 8 outputs into a high-impedance 3-state condition when driven high, allowing multiple CD74HC574M96G4 devices to share the same 8-bit output bus without signal contention. By connecting each device's OE to a separate decoded address or GPIO line, a microcontroller can select which register drives the bus at any time, enabling straightforward I/O port expansion with up to 8 or more parallel latches.

In what supply voltage range does the CD74HC574M96G4 operate and is it compatible with 3.3 V logic systems?

The CD74HC574M96G4 operates from a supply voltage of 2 V to 6 V, covering both 3.3 V and 5 V logic systems. At 3.3 V it meets standard LVTTL input thresholds, making it directly compatible with 3.3 V FPGA I/O banks and microcontrollers without level translation. Its 20 MHz max frequency at 50 pF load is maintained across this range, supporting typical bus clock speeds in 8-bit and 16-bit embedded systems.

What is the difference between the CD74HC574 and the CD74HC374 and when should each be chosen?

Both the CD74HC574 and CD74HC374 are 8-bit D-type flip-flops, but they differ in pin assignment: the CD74HC574 places the clock and OE pins adjacent to the data inputs on one side, while the CD74HC374 has a symmetrical pinout with outputs on one side and inputs on the other. The CD74HC574's pinout is preferred when routing data inputs and outputs on opposite PCB layers, whereas the CD74HC374 suits bus transceiver designs requiring a straight-through 8-bit connection over 20-pin SOIC routing.
