Device Overview
Nexperia 74HC165PW,118 is an 8-bit parallel-in / serial-out shift register with asynchronous parallel loading. It is used to capture eight parallel logic states and shift them out serially.
Selection-Critical Data
| Parameter | Confirmed Data | Engineering Relevance |
|---|---|---|
| Function | 8-bit parallel-in / serial-out shift register | Defines the register width and data-flow direction. |
| Supply voltage | 2.0 to 6.0 V | Must match the board logic supply. |
| Parallel load | Asynchronous 8-bit parallel load | Defines how parallel inputs are captured before serial shifting. |
| Maximum frequency | 61 MHz parametric value for 74HC165PW | Represents shift-clock timing capability, not an RF operating band. |
| Input overvoltage tolerance | Inputs tolerant to 15 V | Defines input-voltage robustness; it is not an accuracy specification. |
| Package | TSSOP-16 | Defines footprint and assembly compatibility. |
