概要
Description
Key features include a wide operating voltage range (2V to 6V), making it compatible with various microcontrollers and systems. The device has a clock input (CP), serial data output (Q7), a serial data input for cascading (DS), and an active-low asynchronous parallel load input (/PL), allowing it to load data directly and asynchronously.
The 74HC165PW is suitable for applications like data acquisition, interfacing with microcontrollers, and increasing the number of input ports. It comes in a TSSOP-16 package, making it ideal for compact designs. Its robust design ensures reliable performance in various digital communication and data processing tasks.

Features
1. 8-bit Parallel Load: It allows for parallel loading of 8 bits of data.
2. Serial Output: The data is shifted out serially, one bit at a time.
3. High Speed: Operates at high speeds typical of CMOS technology.
4. Low Power Consumption: It consumes minimal power, making it suitable for battery-operated devices.
5. Wide Operating Voltage: Functions over a voltage range from 2V to 6V.
6. Compatible with TTL: Inputs are compatible with TTL levels.
7. Cascade Capability: Multiple devices can be cascaded for larger data shifts.
8. Tri-State Outputs: The serial output can be placed in a high-impedance state.
9. Schmitt-Trigger Action: On all inputs, enhancing noise immunity.
These features make the 74HC165PW suitable for applications requiring efficient data conversion from parallel to serial formats.
Pinout
1. Pin Configuration:
- VCC (Pin 16): Supply voltage.
- GND (Pin 8): Ground.
- Q7 (Pin 9): Serial output.
- CP (Pin 2): Clock input, triggers data transfer.
- PL (Pin 1): Parallel load input, active low; loads the parallel data into the shift register.
- CE (Pin 15): Clock enable input, active low; controls the clock operation.
- D0-D7 (Pins 11-4): Parallel data inputs; load data into the register.
- Q7’ (Pin 7): Complementary output of the 8th stage; used for cascading devices.
- SER (Pin 10): Serial input; data shifts in from here.
2. Function:
- The 74HC165PW is an 8-bit serial-in/parallel-out shift register.
- It can capture parallel data inputs and shift them out serially.
- Useful in expanding input ports and interfacing with microcontrollers for data acquisition.
This IC is widely used for increasing the number of input pins available to a system by using a serial interface.
