Device Overview
74HC165BQ,115 is an 8-bit parallel-in/serial-out shift register in DHVQFN-16. It can load eight parallel inputs asynchronously, then shift the stored data out serially under clock control, which is useful for expanding input acquisition with fewer controller pins.
Confirmed Technical and Ordering Data
| Parameter | Confirmed value | Scope / condition |
|---|---|---|
| Logic Function | 8-bit parallel-in/serial-out shift register | parallel or serial data loading |
| Parallel Inputs | D0 to D7 | asynchronous load when PL is LOW |
| Serial Input | DS | serial data path when PL is HIGH |
| Clock Control | CP with CE clock enable | data shifts on LOW-to-HIGH CP transitions when CE is LOW |
| Outputs | Q7 and complementary Q7 | serial outputs |
| Supply Voltage | 2.0 to 6.0 V | 74HC operating range |
| Input Tolerance | Inputs overvoltage tolerant to 15 V | for HIGH-to-LOW level shifting with suitable current limiting |
| Temperature Range | -40 to +125 °C | BQ package ordering table |
| Exact Package | DHVQFN16, SOT763-1 | 16 terminals; 2.5 x 3.5 x 0.85 mm |
Engineering Selection Guidance
Parallel loading occurs when PL is LOW and is asynchronous to the shift clock; serial shifting occurs with PL HIGH and CE LOW on LOW-to-HIGH CP transitions.
The 15 V input-tolerance statement relies on the device's input clamp structure and appropriate current limiting; it is not a 15 V supply rating.
Q7 and complementary Q7 provide opposite-polarity serial outputs, which can simplify cascading or polarity selection in a scan chain.
