What are the key features of CD74ACT574M96?
- 8 independent D-type flip-flops with simultaneous clock for parallel bus-width data latching at 50 pF load
- 3-state outputs with active-low output enable allow direct connection to shared data buses without external buffers
- ACT logic family with 2 V to 6 V supply range combines CMOS low power with TTL-compatible input thresholds
What is CD74ACT574M96 used for?
The CD74ACT574M96 is widely used as an octal register or bus-interface latch in microprocessor-based systems, where it buffers and stores 8-bit data words between CPU buses and peripheral I/O lines. Its 3-state outputs make it ideal for shared bidirectional data bus architectures in FPGAs, DSP boards, and industrial controllers. The 20-pin SOIC package and ACT-family compatibility also suit legacy board designs requiring drop-in replacements for 74F574 or 74S574 devices.

Frequently Asked Questions
How many flip-flops does the CD74ACT574M96 contain, and what is its rated load capacitance?
The CD74ACT574M96 contains 8 non-inverting D-type flip-flops clocked simultaneously by a single common clock input. The device is rated for a load capacitance of 50 pF per output, ensuring reliable signal integrity on typical PCB traces in bus-interface and data-buffering applications without requiring external series termination resistors.
For what supply voltage range is the CD74ACT574M96 specified, and how does it interface with 5 V TTL logic?
The CD74ACT574M96 operates over a 2 V to 6 V supply range, and the ACT family is specifically designed with TTL-compatible input thresholds — logic high is recognized above 2 V and logic low below 0.8 V at a 5 V supply. This makes it a direct interface bridge between 5 V TTL bus drivers and CMOS logic without the need for additional level-translation devices.
When should a designer choose the broadside CD74ACT574M96 instead of the CD74ACT374 for an 8-bit register application?
The CD74ACT574M96 is the broadside pinout version of the 374, meaning its inputs and outputs are arranged on opposite sides of the 20-pin SOIC body. This layout eliminates PCB trace crossovers when routing 8-bit data buses straight across the component, reducing trace length by up to several centimetres on dense boards and simplifying signal integrity management at clock frequencies above 50 MHz.
What advantage does the 3-state output feature of the CD74ACT574M96 provide in multi-master bus architectures?
The active-low output-enable pin tri-states all 8 outputs simultaneously, placing them in a high-impedance state so multiple CD74ACT574M96 devices can share a single 8-bit data bus without bus contention. Each device can be enabled in turn by the bus arbiter, supporting classic 8-bit backplane designs where 4 or more registers drive a common 8-wire bus in time-multiplexed fashion.
