Frequently Asked Questions
What is the SN74ABT573ADWR and what does it do?
The SN74ABT573ADWR is an octal transparent D-type latch with 3-state outputs from Texas Instruments. It belongs to the ABT logic family and features enable-low control, allowing 8 data bits to be latched simultaneously. With a 50pF load capacitance and unidirectional signal path, it is designed for high-speed bus driving and data buffering in digital systems.
What are the key electrical specifications of the SN74ABT573ADWR?
The SN74ABT573ADWR operates with a 50pF load capacitance (CL) and uses an enable-low control signal (OE). It features ABT-family logic levels compatible with 5V TTL and CMOS systems. The device is housed in a 20-pin SOIC package (R-PDSO-G20), is Pb-free (JESD-609 e4 compliant), and has a 15-year estimated end-of-life (YTEOL), ensuring long-term supply availability.
What applications is the SN74ABT573ADWR suitable for?
The SN74ABT573ADWR is ideal for microprocessor address and data bus latching, memory interface buffering, and I/O port expansion. Its 3-state outputs allow multiple devices to share a single bus, making it popular in industrial control systems, communication equipment, and embedded designs using FPGAs or CPLDs that require fast, low-power octal latching.
What package does the SN74ABT573ADWR come in and what are the alternatives?
The SN74ABT573ADWR is available in a 20-pin Small Outline IC (SOIC) package (JEDEC R-PDSO-G20), which is the wide-body SOP20 form factor. Functional alternatives include the SN74ABT573A in TSSOP (DGV suffix), the 74HCT573 for lower-speed 5V designs, and the 74LVT573 for 3.3V systems. The 'D' suffix denotes SOIC and 'WR' indicates tape-and-reel packaging for automated assembly.
