PHILIPS 74HC HCT374 Octal D-type Flip-flop; Positive Edge-trigger; 3-state Data Manual
Summary
The 74HC/HCT374 is an advanced octal D-type flip-flop designed for reliable, high-speed data storage in digital systems. This component features an 8-bit positive, edge-triggered register with three-state non-inverting outputs, making it ideal for bus driving and bus-oriented applications. The manual provides comprehensive technical specifications, including detailed AC/DC electrical characteristics, timing diagrams (setup and hold times), and operational guidelines for both HC and HCT logic families. It serves engineers designing robust digital circuits that require precise data handling, buffering, or memory retention.

Frequently Asked Questions
What is the function of the OE input?
The OE (output enable) input controls whether the output is in a high-impedance OFF-state or drives data.
How do I calculate dynamic power dissipation (PD)?
Use the formula: PD = C × V × f + ∑(C × V × f).
What triggers this flip-flop?
It is positive edge-triggered, meaning it changes state on a LOW-to-HIGH transition of the clock (CP) input.
Is the device compatible with other logic families?
Yes, 74HC/HCT374 are pin compatible with low power Schottky TTL (LSTTL).
What is the maximum operating frequency for the HCT type?
The maximum clock pulse frequency for 74HCT is 21-17 MHz.
