The 74HCT165N,652 is a serial-in, parallel-out shift register. It receives data serially through the SER input and shifts it into the register on each rising edge of the CP (Clock Pulse) input. The SH/LD (Shift/Load) input determines whether the data is shifted or loaded in parallel. When SH/LD is low, the data is shifted, and when it is high, the data is loaded in parallel.
The QH' output provides the serial data output, while the QA to QH outputs provide the parallel data output. The MR (Master Reset) input asynchronously clears the register, setting all outputs to a low state.
The 74HCT165N,652 can be used in various applications that require serial-to-parallel data conversion. Some common application fields include: 1. Data communication systems 2. Industrial automation 3. Robotics 4. LED displays 5. Digital audio equipment
Some alternative models that serve similar functions to the 74HCT165N,652 are: 1. SN74HC165N 2. CD74HC165E 3. MC74HC165AN 4. 74LS165N 5. 74HC165D
These alternatives may have slight differences in specifications, pin configuration, or package type, but they offer similar functionality as serial-in, parallel-out shift registers.
