Frequently Asked Questions
What is the output drive capability of the SN74BCT244DBRE4?
The SN74BCT244DBRE4 can sink up to 64 mA (Iol) at the output, giving it strong drive capability for bus lines and heavily loaded signals in digital systems.
What logic family does the SN74BCT244DBRE4 belong to?
The SN74BCT244DBRE4 belongs to the BCT (Bipolar-CMOS Technology) logic family, which combines high-speed bipolar inputs with CMOS output circuitry for improved performance and compatibility with TTL systems.
How are the outputs controlled on the SN74BCT244DBRE4?
The outputs are controlled by an active-low output enable (OE) signal. When OE is high, all eight outputs enter a high-impedance (3-state) mode, allowing the device to be safely disconnected from a shared bus.
What package is the SN74BCT244DBRE4 available in?
The SN74BCT244DBRE4 is available in a 20-pin SOIC (Small Outline Integrated Circuit) package with the E4 suffix indicating a tape-and-reel packaging option for automated SMT assembly.
