The Texas Instruments SN74HC74N is a dual D-type positive-edge-triggered flip-flop with clear and preset. This article will introduce its pinout, applications and datasheet.
SN74HC74N Description
The Texas Instruments SN74HC74N is a dual D-type positive-edge-triggered flip-flop with clear and preset. It is a logic device that can store one bit of data and change its output state according to the input signals. It has two independent flip-flops, each with a data (D) input, a clock (CLK) input, a clear (CLR) input, a preset (PRE) input, and a complementary output (Q and Q’). The flip-flop can be set or reset by the PRE and CLR inputs, regardless of the clock signal. When PRE and CLR are both high, the flip-flop changes state on the positive-going edge of the clock signal. The SN74HC74N operates from a 2V to 6V supply voltage and can handle clock frequencies up to 60 MHz. It is available in a 14-pin DIP package and is compatible with standard CMOS logic families.

SN74HC74N Features
It is a dual D-type positive-edge-triggered flip-flop with clear and preset. A flip-flop is a logic device that can store one bit of data and change its output state according to the input signals.
It has two independent flip-flops, each with a data (D) input, a clock (CLK) input, a clear (CLR) input, a preset (PRE) input, and a complementary output (Q and Q’). The flip-flop can be set or reset by the PRE and CLR inputs, regardless of the clock signal. When PRE and CLR are both high, the flip-flop changes state on the positive-going edge of the clock signal.
It operates from a 2V to 6V supply voltage and can handle clock frequencies up to 60 MHz. It is available in a 14-pin DIP package and is compatible with standard CMOS logic families.
It can be used for various applications such as converting a momentary switch to a toggle switch, dividing a clock signal by 2 or 4, or storing data in registers or counters.
SN74HC74N Application
The SN74HC74N IC is commonly used in digital circuit design, especially for applications that require flip-flops to store and synchronize data. It operates on a wide voltage range and offers high-speed performance with low power consumption.
