Frequently Asked Questions
What is the output current capability of the SN74F244DB?
The SN74F244DB has a maximum low-level output current (I_OL) of 64mA (0.064A), making it suitable for driving standard TTL and CMOS logic loads in high-speed bus applications with up to 50pF load capacitance.
What package type is the SN74F244DB available in?
The SN74F244DB is housed in a 20-pin SSOP (Small Outline Packages, JESD-30 code R-PDSO-G20), which is a compact surface-mount package ideal for space-constrained PCB designs requiring high-density component placement.
What logic family does the SN74F244DB belong to and what are its speed characteristics?
The SN74F244DB belongs to the F/FAST bipolar logic family, which is known for high-speed switching performance. This family typically offers propagation delays in the low nanosecond range, making it suitable for demanding high-frequency digital systems.
Can the SN74F244DB be used as a replacement for 74HC244 or 74LS244 devices?
The SN74F244DB shares the same pinout and 8-channel non-inverting tri-state buffer function as the 74LS244 and 74HC244, but uses bipolar F/FAST technology. Voltage and current characteristics differ, so verify compatibility with your system's logic levels before substituting.
