Frequently Asked Questions
What is the SN74ABT573ADWRG4 and what does it do?
The SN74ABT573ADWRG4 is a Texas Instruments 8-bit D-type transparent latch with 3-state outputs, part of the ABT (Advanced BiCMOS Technology) logic family. It captures and holds 8 bits of data when the latch enable (LE) input is high and retains the data when LE goes low. The 3-state output enable (OE) pin allows the outputs to be placed in a high-impedance state, making it ideal for shared bus architectures.
What is the supply voltage and operating temperature of SN74ABT573ADWRG4?
The SN74ABT573ADWRG4 operates from a supply voltage of 2.7V to 5.5V, providing compatibility with both 3.3V and 5V logic systems. The operating temperature range is -40°C to +85°C (industrial grade), making it suitable for demanding industrial and telecommunications environments.
What package is SN74ABT573ADWRG4 available in?
SN74ABT573ADWRG4 comes in a 20-pin wide-body SOIC (DW) package in tape-and-reel format (suffix G4), with 1.27mm pitch. The wide SOIC body offers better thermal dissipation than standard-width SOIC and is suitable for automated PCB assembly. Pin count is 20.
What are common applications for SN74ABT573ADWRG4?
Common applications include microprocessor and DSP address/data bus buffering, FPGA and CPLD I/O expansion, memory interface latching, industrial PLC I/O modules, and server backplane bus isolation. Its bus-hold feature and 3-state outputs make it particularly well-suited for multi-master bus designs.
What are compatible alternative parts for SN74ABT573ADWRG4?
Pin-compatible and functionally equivalent alternatives include 74ALVCH573 (lower voltage, higher speed), 74LVC573A (3.3V logic), SN74LVTH573 (LVTH family, 3.3V), and 74HCT573 (HCT family, 5V). For drop-in replacement in 5V designs, SN74ABT573A (PDIP/SOIC) from TI or equivalent from NXP (74ABT573) are recommended.
