Présentation
Description
Key features include:
- Logic Type: Octal D-type flip-flop
- Outputs: Tri-state, allowing multiple devices to share the same output lines
- Operating Voltage: Typically operates from 2V to 6V
- High-Speed Operation: With propagation delays significantly lower than earlier logic types
- Input Compatibility: TTL and CMOS compatible
- Latch Enable: Controlled by a clock input, data is transferred to the output on the rising edge of the clock
- Output Enable: A separate control pin to tri-state the outputs for bus-oriented applications
The device is commonly used in registers, latches, and buffer applications where multiple bits of data need to be stored or transferred simultaneously. Its robust design ensures reliable performance in diverse electronic applications.

Pinout
Key pin functionalities include:
- VCC (Pin 20): Power supply pin.
- GND (Pin 10): Ground pin.
- D0 to D7 (Pins 2, 3, 4, 5, 6, 7, 8, 9): Data input pins for each flip-flop.
- Q0 to Q7 (Pins 19, 18, 17, 16, 15, 14, 13, 12): 3-state output pins for each flip-flop.
- CLK (Pin 11): Clock input pin; data is transferred to the output on the rising edge.
- OE (Pin 1): Output enable pin; when low, the outputs are enabled, and when high, the outputs are in a high-impedance state.
The SN74HC374N is commonly used in digital systems for data latch purposes due to its ability to isolate and hold data efficiently.
