Frequently Asked Questions
What is the SN74AC574PWRG4 and what does it do?
The SN74AC574PWRG4 is an octal (8-bit) D-type edge-triggered flip-flop with 3-state outputs from Texas Instruments. It captures 8-bit parallel data on the rising edge of the clock and can drive or release a common data bus via its enable-low output-control pin, making it ideal for bus interfacing in microprocessor and digital logic systems.
What are the key electrical specifications of the SN74AC574PWRG4?
The SN74AC574PWRG4 operates on a 2V–5.5V supply voltage, supports a load capacitance of 50pF, and is built on Texas Instruments' AC-family CMOS process. The JESD-30 package code is R-PDSO-G20 (20-pin TSSOP small outline). It features enable-low output control and unidirectional count direction, with propagation delays typically under 8ns at 5V.
What is the difference between SN74AC574 and SN74AC374?
The SN74AC574PWRG4 is the broadside pinout version of the SN74AC374. Both are octal D-type edge-triggered flip-flops with 3-state outputs and identical logic functionality; however, the SN74AC574 rearranges the input and output pins to a broadside (parallel) layout, which simplifies PCB routing when inputs and outputs need to be on opposite sides of the device.
Is the SN74AC574PWRG4 RoHS compliant and lead-free?
Yes, the SN74AC574PWRG4 is fully Pb-free and carries the 'G4' suffix indicating RoHS compliance. The JESD-609 code is e4, confirming the device meets international environmental regulations for lead-free soldering, making it suitable for modern green manufacturing processes.
What are typical applications for the SN74AC574PWRG4?
Typical applications include data bus buffering and latching in microprocessor systems, address register storage, memory interface circuits, industrial controllers, and FPGA I/O expansion boards. The 3-state outputs allow multiple SN74AC574 devices to share a common 8-bit bus without signal contention, which is essential in multi-master digital architectures.
