Frequently Asked Questions
What is the function of the SN74LVC573AQDWREP?
The SN74LVC573AQDWREP is an 8-bit octal transparent D-type latch with 3-state outputs. It captures parallel 8-bit data when the latch enable input is high and holds that data on the outputs when enable goes low, acting as an 8-bit bus buffer and data register.
What voltage range does the SN74LVC573AQDWREP support?
As part of the LVC/LCX/Z logic family, the SN74LVC573AQDWREP supports operation from 1.65V to 5.5V supply voltage, making it compatible with modern 1.8V, 2.5V, 3.3V, and legacy 5V logic systems in mixed-voltage designs.
What makes the SN74LVC573AQDWREP suitable for automotive applications?
The 'Q' suffix indicates automotive-grade qualification and the 'EP' suffix denotes enhanced product status, meaning the device has been tested and verified for AEC-Q100 reliability standards and extended temperature ranges required by automotive electronic control units.
What package does the SN74LVC573AQDWREP use?
The SN74LVC573AQDWREP is housed in a 20-pin SOIC (Small Outline Integrated Circuit) package with JESD-30 code R-PDSO-G20, a standard surface-mount package compatible with automated PCB assembly and widely used in automotive and industrial electronic designs.
What is the output low current capability of the SN74LVC573AQDWREP?
The SN74LVC573AQDWREP provides a maximum output low current (I(ol)) of 24 mA, enabling it to drive multiple bus loads simultaneously with adequate current drive to maintain valid logic levels across high-capacitance address and data bus lines.
