Features
1. 8 Flip-Flops: Contains eight D-type flip-flops with a common clock and clear input.
2. 3-State Outputs: The outputs can be set to high, low, or high-impedance state, facilitating bus interfacing.
3. Wide Operating Voltage: Operates efficiently across a 2V to 6V range.
4. High-Speed Operation: Features typical propagation delay times of around 14ns at 5V.
5. Low Power Consumption: CMOS technology ensures low static power dissipation.
6. Direct LSTTL Input Compatibility: Compatible with TTL logic levels, making it versatile for mixed voltage systems.
7. Standard Pin Configuration: Conforms to industry-standard 20-pin DIP package, simplifying PCB layout.
8. Latch Enable: Equipped with a clock input (CLK) to control data storage in flip-flops.
These features make the SN74HC574N suitable for applications requiring temporary data storage, data transfer in microcontrollers, and interfacing with multiple data lines.
Pinout
Here’s a concise breakdown of its pin configuration:
1. Pins 1-8 and 10-17: These are the D0-D7 data input pins corresponding to the eight flip-flops.
2. Pin 9 (GND): Ground connection for the circuit.
3. Pin 19 (OE): Output Enable input, active low. When low, the data is output; when high, the outputs are in a high-impedance state.
4. Pin 11 (CLK): Clock input; data is latched on the rising edge of the clock pulse.
5. Pin 20 (VCC): Supply voltage pin.
The SN74HC574N is commonly used in applications requiring temporary data storage, data buffering, or interfacing between different logic levels.
