The SN74LV165A is a bipolar 8-bit parallel-in/serial-out shift register. It is classified as a logic - shift register, and is used in a range of applications where the transfer of data is required.The SN74LV165A has an 8-bit wide parallel I/O port that accepts data at the inputs, which is then shifted out through a single serial output line. They are useful for the transfer of data from one device to another, or to a single device. One example is in the control of DC motors, where the data can be sent from the controller to the motor in parallel, then the motor can act on the data as they come in sequentially.The shift register also has multiple internal latches which allow the data to be stored (using the latch inputs) and transmitted at the rate of the clock signal driving the shift register. This makes the SN74LV165A suitable for synchronizing data flow between two devices, as long as they are connected with a synchronous link.The operation of the SN74LV165A is controlled by the control signals. The Enable pin (EN) is used to enable the register. The Shift/Load input (S/L) allows the user to choose between two operating modes: ‘shift’ and ‘load’. When the S/L input is set to ‘high’ the SN74LV165A works in ‘shift’ mode, and when it is set to ‘low’ it will work in ‘load’ mode.In shift mode, data is shifted into the register on the rising edge of the appropriate clock pulse, and is shifted out through the serial output. In load mode, the data is latched into the register on the rising edge of the appropriate clock pulse.The SN74LV165A is able to operate on logic supply voltages from 2.7V to 5.5V, making it compatible with many different types of logic devices, including TTL, CMOS and LVDS technologies. It features low current consumption and low propagation delay. The SN74LV165A also features a breakdown voltage of 3.6V, making it suitable for use in automotive and other high-voltage applications.In summary, the SN74LV165A is a highly versatile logic - shift register that can be used in a wide range of applications. It can shift and transmit data reliably at high speeds, making it suitable for a variety of synchronous link applications. It has a wide logic supply voltage range, low power consumption and low propagation delay, making it suitable for many types of logic devices.
