ON Semiconductor MC74HC165ANG 8-Bit Parallel-Load Shift Registers

The MC74HC165ANG is a high-performance CMOS 8-bit parallel-load shift register designed and manufactured by ON Semiconductor, a leader in energy-efficient innovations. This integrated circuit is primarily used for serial-to-parallel data conversion and is a vital component in digital systems where interfacing with microprocessors, microcontrollers, or other digital systems is necessary.

The device features an 8-bit parallel input and an 8-bit serial output register that operates at a wide voltage range from 2V to 6V, making it suitable for various applications. Its high-speed operation, low power consumption, and compatibility with TTL (Transistor-Transistor Logic) make it a versatile choice for designers. The MC74HC165ANG is capable of direct interfacing with the CMOS, NMOS, and TTL logic levels, ensuring seamless integration into existing systems.

The parallel-load shift register is equipped with two modes of operation: parallel (load) and serial (shift). In the load mode, data is entered into the register simultaneously from the eight parallel inputs. When in the shift mode, data is shifted out serially at the QS and Q'S outputs, providing an efficient way to read multiple discrete inputs through a single serial interface.

Additional features include a Master Reset (MR) input that clears the register, setting all outputs to a low state. The Clock Inhibit (CLK INH) input can be used to control the clock and thus manage the timing of the data transfer. The outputs can drive up to 10 LSTTL loads, which is a testament to the device's strong output capability.

ON Semiconductor's MC74HC165ANG comes in a PDIP-16 package, ensuring easy integration into through-hole PCB designs. This shift register is commonly used in data acquisition systems, microprocessor-based systems, computer interfaces, and remote control applications where efficient data aggregation is crucial.

With its reliable performance and robust design, the MC74HC165ANG from ON Semiconductor stands out as an excellent choice for designers looking to implement an 8-bit shift register in their digital systems.
