The SN74HC165ANSR has a total of 16 pins. The detailed pin configuration is as follows:
Advantages: - High-speed operation enables quick data transfer. - Cascadable feature allows for expanding the number of parallel outputs. - Small package size (SOIC) makes it suitable for space-constrained applications.
Disadvantages: - Limited number of parallel outputs (8 bits). - Requires an external clock signal for operation.
The SN74HC165ANSR is a serial-in, parallel-out shift register. It receives serial data input through the SER pin and shifts the data into its internal storage registers on each rising edge of the clock signal applied to the CLK pin. The parallel output is available on the D0-D7 pins. The shift/load operation is controlled by the SH/LD pin. When SH/LD is low, the shift operation is enabled, allowing the data to be shifted in. When SH/LD is high, the load operation is enabled, latching the data from the serial input into the parallel output registers.
The SN74HC165ANSR can be used in various applications, including:
