Frequently Asked Questions
What logic function does the SN74LV374ATPWR perform?
The SN74LV374ATPWR is an octal (8-channel) D-type flip-flop with 3-state outputs. On each rising clock edge, the 8 data inputs are latched to the outputs. The output enable pin controls whether the outputs are driven or placed in a high-impedance state, enabling multi-device bus sharing.
What is the maximum operating frequency of the SN74LV374ATPWR?
The SN74LV374ATPWR is rated for a maximum operating frequency of 50MHz at nominal supply voltage. This makes it suitable for high-speed bus applications such as address latching in microcontroller and DSP systems where fast data capture is critical.
What voltage levels does the SN74LV374ATPWR support?
The SN74LV374ATPWR belongs to the LV/LV-A/LVX/H logic family, designed for low-voltage 3.3V operation while maintaining compatibility with 5V-tolerant inputs. This makes it easy to interface between legacy 5V logic and modern 3.3V microcontrollers or FPGAs in mixed-voltage designs.
What package does the SN74LV374ATPWR come in?
The SN74LV374ATPWR is packaged in a 20-Pin TSSOP (Thin Shrink Small Outline Package) surface-mount format. It has a RoHS-compliant e4 lead-free finish and is available on tape and reel (TPWR suffix) for automated pick-and-place assembly in production environments.
How does the SN74LV374ATPWR differ from the SN74HC374?
The SN74LV374ATPWR uses the LV (Low Voltage) logic process optimized for 3.3V supply rails, compared to the HC family which is primarily designed for 5V operation. The LV variant offers lower power consumption at 3.3V and is better suited for mixed-voltage or battery-powered designs where reducing supply voltage improves efficiency.
