Frequently Asked Questions
What is the function of the SN74HC374ADB?
The SN74HC374ADB is an octal edge-triggered D-type flip-flop that captures 8 bits of parallel input data on the rising edge of the clock signal and stores them, with 3-state outputs controlled by a common output-enable pin for bus sharing.
What does the 3-state output on the SN74HC374ADB mean?
The 3-state outputs allow the SN74HC374ADB outputs to be placed in a high-impedance state when the output-enable pin is deasserted, enabling multiple devices to share a common bus without electrical conflict.
What logic family does the SN74HC374ADB belong to?
The SN74HC374ADB belongs to the HC (High-speed CMOS) logic family, which provides low power consumption, high noise immunity, and TTL-compatible input thresholds, making it suitable for both CMOS and mixed-logic system designs.
What package is the SN74HC374ADB available in?
The SN74HC374ADB is packaged in a 20-pin SSOP (Shrink Small Outline Package), a compact surface-mount package with a smaller pitch than standard SOIC, ideal for high-density PCB designs in digital logic applications.
