This table gives cross-reference parts and alternative options found for SN74ACT74DBR. 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 SN74ACT74DBR, 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.
The recommended operating voltage range for the SN74ACT74DBR is 4.5V to 5.5V, although it can operate as low as 3.5V with reduced performance.
It is recommended to power up the VCC pin before the input signals, and power down the VCC pin after the input signals. This ensures that the device is properly initialized and avoids any potential latch-up or damage.
The maximum frequency of operation for the SN74ACT74DBR is typically around 100 MHz, although this can vary depending on the specific application and operating conditions.
It is recommended to use a termination resistor (e.g. 50 ohms) at the output of the device to prevent signal reflections and ensure proper signal integrity.
Yes, the SN74ACT74DBR can be used in a 3.3V system, although the output voltage levels may not be as high as those in a 5V system. Additionally, the device may not meet the full specifications at 3.3V, so it's recommended to consult the datasheet and perform thorough testing.
