SN74LS28DR Frequently Asked Questions (FAQ)
-
The maximum operating frequency of the SN74LS28DR is 35 MHz, but it can vary depending on the load capacitance and the output current.
-
To ensure reliable operation in high-temperature environments, it is recommended to follow proper thermal management practices, such as providing adequate heat sinking and airflow, and ensuring that the device is operated within its recommended operating temperature range of -40°C to 85°C.
-
The SN74LS28DR is a 5V device, but it can be used in a 3.3V system with some limitations. The output voltage will be reduced, and the device may not meet its specified timing parameters. It is recommended to use a level translator or a voltage regulator to ensure proper operation.
-
The SN74LS28DR has built-in ESD protection, but it is still recommended to follow proper ESD handling practices, such as using an ESD wrist strap or mat, and storing the devices in anti-static packaging.
-
The SN74LS28DR is not a radiation-hardened device, and it is not suitable for use in radiation-hardened applications. Texas Instruments offers radiation-hardened versions of some of its devices, but the SN74LS28DR is not one of them.
