Frequently Asked Questions
What is the ABT family and how does it differ from standard CMOS?
ABT (Advanced BiCMOS Technology) is a Texas Instruments logic family that combines bipolar output drive with CMOS input levels, delivering higher output current and faster switching speeds than standard CMOS. The SN74ABT574APW benefits from this with superior bus driving capability at 5V, lower propagation delays, and improved noise immunity compared to standard LV or LVC families.
What package does the SN74ABT574APW use?
The SN74ABT574APW is housed in a TSSOP-20 package (JESD-30 Code: R-PDSO-G20), which is the broadside version of the 374 pinout. In this configuration, data inputs (D0-D7) and outputs (Q0-Q7) are arranged on opposite sides of the package, simplifying PCB routing for bus register and latch applications.
How does the 3-state output work on the SN74ABT574APW?
The 3-state output is controlled by an active-low output enable (OE) pin. When OE is low, all eight outputs are driven to their registered logic state. When OE is high, all outputs enter a high-impedance state, effectively disconnecting the device from the bus and allowing other drivers to control the shared bus lines.
What are typical applications for the SN74ABT574APW?
Common applications include data bus registers, output port latches, address registers, and memory interface buffers in microprocessor-based systems. The device is also used in bus isolation, I/O port expansion, and backplane register applications in industrial automation, telecommunications, and embedded computing equipment requiring high-speed 8-bit parallel data handling.
Is the SN74ABT574APW RoHS compliant?
Yes, the SN74ABT574APW is fully RoHS compliant and lead-free (Pb-free Code: Yes, JESD-609 Code: e4), meeting EU RoHS Directive requirements for restriction of hazardous substances. This makes it suitable for environmentally regulated markets and modern electronics manufacturing with lead-free solder processes.
