Frequently Asked Questions
What is the SN74ABT573ADWRE4?
The SN74ABT573ADWRE4 is a Texas Instruments 8-bit D-type transparent latch with 3-state outputs. It belongs to the ABT (Advanced BiCMOS Technology) logic family and is packaged in a 20-pin SOIC (SOIC-20) wide-body package on tape and reel. It operates from a 2.7V to 5.5V supply and offers fast switching with approximately 3.5ns propagation delay at 3.3V.
What are the key electrical specifications of the SN74ABT573ADWRE4?
Key specs: supply voltage 2.7V–5.5V, propagation delay ~3.5ns (3.3V), output sink/source current ±32mA, VIH = 2.0V, VIL = 0.8V, operating temperature -40°C to +85°C. The 3-state outputs allow multiple devices to share a common bus.
What are the typical applications for the SN74ABT573ADWRE4?
This device is widely used for address latching and data bus buffering in microprocessor systems, memory interfaces (SRAM, Flash), industrial PLC I/O modules, and FPGA/CPLD peripheral circuits. Its 3-state outputs make it ideal for shared bus architectures where multiple drivers must be isolated.
What are compatible alternatives to the SN74ABT573ADWRE4?
Compatible alternatives include the 74ALVC573 (3.3V, faster), SN74LVC573A (LVC logic, 1.65–5.5V), 74HCT573 (HCT family, 5V only), and SN74AHCT573 (AHCT, 4.5–5.5V). For drop-in functional equivalents from other vendors, consider the NXP 74ABT573AD or ON Semiconductor MC74ABT573A.
Is the SN74ABT573ADWRE4 RoHS compliant and what is its MSL rating?
Yes, the SN74ABT573ADWRE4 is fully RoHS compliant and lead-free. It has a Moisture Sensitivity Level (MSL) rating of MSL 1, meaning it requires no special handling or baking before reflow soldering. The device is supplied on tape and reel (RE4 suffix) for automated SMT assembly.
