Frequently Asked Questions
What is the maximum operating voltage for the SN74ABT8245DW?
The SN74ABT8245DW operates with a VCC range of 2.7V to 3.6V, with an absolute maximum of 3.6V. It is optimized for 3.3V logic systems and is not intended for 5V-only supply operation, though its inputs are 5V-tolerant.
What applications is the SN74ABT8245DW best suited for?
This device is best suited for bidirectional data bus buffering in computers, servers, and industrial controllers. Its 8-bit bidirectional architecture with direction control (DIR pin) and output enable (OE pin) makes it ideal for backplane bus interfaces, memory bus expansion, and multi-master bus arbitration designs.
How does the SN74ABT8245DW compare to the 74LVC245 or 74HC245?
Compared to 74HC245, the SN74ABT8245DW offers significantly higher speed and stronger output drive (24mA vs 8mA typical). Versus 74LVC245, it provides compatible voltage range but uses ABT (Advanced BiCMOS Technology) for lower propagation delay, typically under 4ns, making it preferable in high-speed bus applications.
What package does the SN74ABT8245DW come in?
The SN74ABT8245DW comes in a 20-pin SOIC wide-body (DW) package with 7.5mm body width. This through-hole-compatible surface-mount package is easy to solder manually or with reflow processes and is widely available from distributors.
