Alternate Parts for SN74LS674DW
This table gives cross-reference parts and alternative options found for SN74LS674DW. 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 SN74LS674DW, 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 maximum clock frequency of the SN74LS674DW is 20 MHz.
The SN74LS674DW requires a single 5V power supply, and it's recommended to use a decoupling capacitor of 0.1uF to 1uF between VCC and GND to ensure proper operation.
The SN74LS674DW can sink or source up to 24mA of current per output pin.
The RST input should be tied to VCC through a pull-up resistor (e.g., 1kΩ) and connected to a reset signal or a push-button switch to ensure proper reset operation.
No, the SN74LS674DW is designed to operate at 5V, and using it in a 3.3V system may not guarantee proper operation or may even damage the device.
