Frequently Asked Questions
What is the operating voltage and input compatibility of the SN74LVC573APW?
The SN74LVC573APW operates from a 2.7V to 3.6V supply (nominal 3.3V) and features 5V-tolerant inputs, allowing it to interface directly with both 3.3V and 5V logic systems without external level-shifting components.
What are the output drive capabilities of the SN74LVC573APW?
The device provides a maximum low-level output current (I_OL) of 24mA and is characterized with a 50pF load capacitance, making it suitable for driving moderate bus loads in microprocessor address/data bus applications.
How does the latch enable control work on the SN74LVC573APW?
The SN74LVC573APW uses an active-low enable (LE) pin. When LE is high, data on the D inputs passes transparently to the outputs. When LE goes low, the last data state is latched and held on the outputs regardless of input changes, enabling stable bus hold during bus contention.
What package does the SN74LVC573APW use and what are its dimensions?
The SN74LVC573APW comes in a 20-pin TSSOP (Thin Shrink Small Outline Package, JESD-30 code R-PDSO-G20), which offers a compact footprint suitable for high-density PCB layouts in portable and space-constrained applications.
What are common alternatives or substitutes for the SN74LVC573APW?
Common alternatives include the SN74LVC573A in other packages (SOIC, TSSOP variants), the 74LCX573 for lower voltage operation, and the SN74AHCT573 for 5V AHCT-family systems. For drop-in replacements, ensure matching pinout, voltage range, and output drive specifications.
