Frequently Asked Questions
What is the operating voltage range of SN74LVC573ANSR?
The SN74LVC573ANSR operates from 1.65V to 3.6V supply voltage, making it suitable for 1.8V, 2.5V, and 3.3V systems. Its inputs are also 5V-tolerant, allowing direct interfacing with 5V logic without level-shifting components.
What are the typical applications for SN74LVC573ANSR?
SN74LVC573ANSR is commonly used for address and data bus latching in microprocessor systems, I/O port expansion, memory interface circuits, and bus driving applications. Its 3-state outputs enable it to share a common bus in systems with multiple drivers.
How does the ENABLE LOW control pin work on SN74LVC573ANSR?
The active-low Output Enable (OE) pin controls the 3-state outputs. When OE is LOW, the latched data appears on the outputs. When OE is HIGH, all outputs enter a high-impedance state, effectively disconnecting the device from the bus without affecting the internal latch state.
What package is SN74LVC573ANSR and what are its dimensions?
SN74LVC573ANSR comes in a 20-pin Small Outline (SOIC) package, JESD-30 code R-PDSO-G20. The NSR suffix indicates a tape-and-reel packaging option for automated PCB assembly, with a typical body width of 7.5mm and 1.27mm pin pitch.
