Frequently Asked Questions
What is the SN74ABT573ADW and what does it do?
The SN74ABT573ADW is an octal (8-bit) D-type transparent latch with 3-state outputs from Texas Instruments. When the latch enable (LE) pin is HIGH, data on the D inputs passes through to the Q outputs. When LE goes LOW, the outputs retain the last data state, making it ideal for bus data capture and address latching in digital systems.
What are the key electrical specifications of the SN74ABT573ADW?
The SN74ABT573ADW operates on a 4.5V to 5.5V supply voltage and features 5V-tolerant inputs, allowing interfacing with both 3.3V and 5V logic. It supports output current of ±32mA, propagation delay as low as 4.2ns (typical), and can drive heavily loaded 50Ω bus lines. The device comes in a 24-pin wide SOIC (DW) package.
What is the difference between the SN74ABT573 and SN74ABT574?
The SN74ABT573ADW is a transparent latch — outputs follow inputs while the latch enable (LE) is HIGH. The SN74ABT574 is a D flip-flop that captures data on the rising clock edge. Use the 573 when you need level-sensitive data hold (e.g., address latching with ALE signal), and the 574 when you need edge-triggered synchronous storage.
What package does the SN74ABT573ADW come in?
The SN74ABT573ADW comes in a 24-pin wide SOIC package (DW suffix), with a body width of 7.5mm. Texas Instruments also offers the same logic function in other packages such as the 20-pin SSOP (DB) and 24-pin TSSOP, depending on your board space and thermal requirements.
How do I order or get a quote for the SN74ABT573ADW?
The SN74ABT573ADW is priced from approximately $0.50 per unit and is available through FindMyChip with worldwide shipping. You can submit an RFQ directly on this page to request a bulk quote, check real-time stock availability, and get competitive pricing from verified distributors.
