The MC74HC165A is a parallel-in-serial-out 8-bit shift register with a register-enable terminal and an asynchronous master reset terminal. It is typically used to interface with an 8-bit parallel data bus in order to convert the 8-bit parallel data bus into multiple serial bytes of data. It is also useful for other applications that require serial data transfer. As a logic circuit, MC74HC165A is classified as a Shift Register and falls within the family of Logic Registers.
The MC74HC165A device is constructed with an 8-bit serial input, one clock input, register-enable input, asynchronous reset input, and eight buffered parallel output pins. The device is basically a “register-file” circuit that can transfer data from the serial input, via a latching clock signal, to the parallel output. It is optimized to operate in high speed and low power dissipation. The high speed capabilities of the device make it ideal for applications that require fast data transfer.
The logic symbols for the MC74HC165A are illustrated in Figure 2. As shown, the device has eight output pins, several of which are labeled in the figure. The inputs are labeled Clock (CP), Serial In (SER), Register Enable (E), and Reset (R). The Register-Enable (E) functions to latches the contents of the serial input (SER) into the output register at the rising edge of the Clock (CP) input signal. Conversely, at the falling edge of the Clock (CP) input signal, the contents of the output register will be preserved.
The Reset input signal (R) resets all the output pins to low logic level and sets the data inputs to the high-impedance state. This reset condition is internally maintained until the asynchronous reset signal is deasserted. It is important to note that the Reset signal must remain low for the entire period of low clock high time for proper device operation.
The MC74HC165A shift register is primarily used in applications that require serial-to-parallel data conversion, particularly in digital signal processing (DSP) systems. It can also be used to create shift registers with long delay periods. With its low power consumption and high speed capabilities, it is suited for a wide variety of data transfer applications, including flash memory devices, serial display drivers, and communication interface circuits.
The device is generally used in a “parallel-in/parallel-out” environment. The data is loaded into the register at the rising edge of the Clock (CP) input signal and is latched into the registers on the falling edge. The enabled outputs will now have the parallel data present. This data is then shifted out on each subsequent rising edge of the Clock signal until all of the data has been shifted out. After all of the data has been shifted out, the register is reset by bringing the Reset signal (R) low for a short time.
In conclusion, the MC74HC165A is a parallel-in-serial-out 8-bit shift register with a register-enable terminal and an asynchronous master reset terminal. It is typically used to interface with an 8-bit parallel data bus in order to convert the 8-bit parallel data bus into multiple serial bytes of data. It is also useful for other applications that require serial data transfer, such as digital signal processing, flash memory devices, serial display drivers, and communication interface circuits. By optimizing its high speed and low power consumption, the MC74HC165A can easily meet the requirements of data transfer applications.
