Pinout
The primary function of the SN74HC174 is to store and synchronize digital data. It features six independent D-type flip-flops, each with a D (data) input, a clock input, and a Q (output). Additionally, the device includes a common clock and an asynchronous clear input.
The pin configuration is typically as follows:
- Pins 1, 3, 5, 9, 11, 13: Data inputs (D1 to D6)
- Pins 2, 4, 6, 8, 10, 12: Outputs (Q1 to Q6)
- Pin 14: Clear input (CLR)
- Pin 15: Clock input (CLK)
- Pin 16: Positive supply voltage (VCC)
- Pin 7: Ground (GND)
The clear input is active-low, meaning that when the CLR pin is low, all Q outputs are reset to low, regardless of the clock state. The device operates on a power supply voltage ranging from 2V to 6V.
