Frequently Asked Questions
How many data inputs can each multiplexer section of the CD74ACT253M select from?
Each of the 2 multiplexer sections in the CD74ACT253M can select from 4 inputs, controlled by 2 common address lines. The 4-bit wide selection per section, combined with tri-state outputs, makes it effective for routing data across a shared 4-bit bus.
What is the output drive current of the CD74ACT253M and why does it matter for bus driving?
The CD74ACT253M provides a maximum low-level output current (I_OL) of 24 mA, enabling it to drive standard TTL and CMOS loads on shared bus lines. This 24 mA drive strength ensures signal integrity even on PCB traces with 50 pF capacitive loading.
How does the tri-state output of the CD74ACT253M help in multi-source bus architectures?
The tri-state outputs of the CD74ACT253M can be disabled via an output enable pin, placing outputs in a high-impedance state. This prevents bus contention when multiple drivers share the same 4-bit data bus, a critical requirement in microprocessor and memory interfacing designs.
In which package does the CD74ACT253M come and how does it compare to DIP versions for modern PCB designs?
The CD74ACT253M is housed in a 16-pin SOIC package (R-PDSO-G16), which has a significantly smaller PCB footprint than equivalent DIP versions. SMT SOIC placement is compatible with standard automated assembly processes, reducing board size by roughly 50% compared to through-hole DIP packages.
