Procurement Notes
Verify the specific manufacturer suffix against official datasheets to confirm pinout and electrical characteristics. Ensure the component matches the required surface-mount package dimensions and thermal specifications for the target application environment before integration.
Selection Notes
Select this component when open-collector NAND functionality is required in a compact surface-mount form factor. Consider the 74 series speed and drive capabilities relative to system timing requirements and load conditions.
Part Context
This part belongs to the widely adopted 74 series family of logic integrated circuits. It provides fundamental NAND gating functions essential for building complex digital systems. The D suffix indicates the specific SOIC package variant used for surface-mount PCB assembly.
FAQ
What type of output does the SN7438D provide?
It provides open-collector outputs, which require an external pull-up resistor for proper high-state operation.
Is the SN7438D suitable for through-hole mounting?
No, the 'D' suffix denotes a surface-mount SOIC package; through-hole versions typically use different suffixes like 'N'.
