MC74HC74AN - Motorola

Description: The MC54/74HC74A is identical in pinout to the LS74. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. This device consists of two D flip–flops with individual Set, Reset, and Clock inputs. Information at a D–input is transferred to the corresponding Q output on the next positive going edge of the clock input. Both Q and Q outputs are available from each flip–flop. The Set and Reset inputs are asynchronous.

MC74HC74AN Frequently Asked Questions (FAQs)

The recommended operating voltage range for the MC74HC74AN is 2V to 6V, with a typical voltage of 5V.
The asynchronous reset input (CLR) should be tied to VCC through a pull-up resistor or connected to a logic high signal to ensure proper operation. A low signal on CLR will reset the flip-flop.
The maximum clock frequency that the MC74HC74AN can handle is 25 MHz, but this can vary depending on the operating voltage and load capacitance.
Yes, the MC74HC74AN can operate at 3.3V, but the output voltage levels may not be as high as those at 5V, and the device may not be as fast.
To ensure proper power-up and initialization, the VCC pin should be ramped up slowly (typically 10-20 ms) to prevent latch-up and ensure that the internal circuitry is properly initialized.
