Frequently Asked Questions
What is the difference between the CD74HCT374E-NG and standard HC-series flip-flops?
The CD74HCT374E-NG belongs to the HCT series, which features TTL-compatible input thresholds, allowing it to interface directly with 5V TTL logic without level-shifting. Standard HC-series devices use CMOS input thresholds that may not reliably interpret TTL logic levels, making HCT the preferred choice in mixed TTL/CMOS designs.
How many flip-flops are in the CD74HCT374E-NG and what triggers them?
The CD74HCT374E-NG contains eight D-type flip-flops, all triggered on the positive (rising) edge of the clock signal. This makes it suitable for synchronous 8-bit data capture, register operations, and pipeline stages in digital logic and microprocessor systems.
What does the three-state output mean for the CD74HCT374E-NG?
Three-state outputs mean the CD74HCT374E-NG can be placed in a high-impedance state via the output-enable pin, effectively disconnecting it from the bus. This allows multiple devices to share the same data bus without signal conflicts, which is essential in memory interfaces and multiplexed bus architectures.
What package options are available for the CD74HCT374E-NG?
The CD74HCT374E-NG comes in a 20-pin DIP (Dual In-Line Package), which is ideal for through-hole PCB assembly and breadboard prototyping. For surface-mount applications, Texas Instruments offers equivalent HCT374 variants in SOIC or TSSOP packages.
