Alternate Parts for SN74LS90DR
This table gives cross-reference parts and alternative options found for SN74LS90DR. The Form Fit Function (FFF) tab will give you the options that are more likely to serve as direct pin-to-pin alternates or drop-in parts. The Functional Equivalents tab will give you options that are likely to match the same function of SN74LS90DR, but it may not fit your design. Always verify details of parts you are evaluating, as these parts are offered as suggestions for what you are looking for and are not guaranteed.
SN74LS90DR Frequently Asked Questions (FAQ)
-
The maximum clock frequency of the SN74LS90DR is 2.5 MHz, but it can vary depending on the specific application and operating conditions.
-
The SN74LS90DR requires a single 5V power supply, and it's essential to ensure that the power supply is clean and stable. A decoupling capacitor of 0.1 μF to 1 μF should be placed close to the device to filter out noise and voltage spikes.
-
The SN74LS90DR can sink or source up to 16 mA of current per output pin, but it's recommended to limit the current to 10 mA or less to ensure reliable operation.
-
The asynchronous reset input (R) should be tied to VCC through a pull-up resistor (typically 1 kΩ to 10 kΩ) to ensure that the device is properly reset. A capacitor (typically 10 nF to 100 nF) can be added in parallel to the resistor to filter out noise.
-
To minimize noise and signal degradation, it's recommended to keep the clock signal traces short and away from other signals. Use a ground plane or a power plane to reduce noise and ensure that the device is properly decoupled.
