Product details
Overview
74HC165D-Q100 from Nexperia is an AEC-Q100 Grade 1 qualified 8-bit parallel-in/serial-out shift register in SO16 package, featuring asynchronous parallel load (PL), synchronous serial shift (CP/CE), complementary Q7/Q7 outputs, and overvoltage-tolerant inputs up to 15 V for high-to-low level shifting. It operates from -40 °C to +125 °C and supports CMOS-level logic with 6 V max supply voltage.
For engineers reviewing the 74HC165D-Q100 datasheet, 74HC165D-Q100 pinout, 74HC165D-Q100 application, or 74HC165D-Q100 equivalent, key selection criteria include parallel-load latency (14 ns @ 6 V), serial-shift propagation delay (15 ns @ 6 V), clock frequency capability (35 MHz @ 6 V), and automotive-grade thermal robustness across extended temperature range.
Technical Context
This device implements a synchronous 8-bit shift register with dual input modes: asynchronous parallel load via active-low PL enables immediate capture of D0–D7, while serial data enters at DS under CP edge-triggered control when CE is low. The register provides both true (Q7) and inverted (Q7) serial outputs for flexible interface timing and signal integrity.
Input overvoltage tolerance (up to 15 V) allows direct interfacing with higher-voltage logic domains without external level-shifting circuitry. Its CMOS input structure ensures low static current (≤160 μA @ 125 °C) and compatibility with JEDEC Std 7A, supporting reliable operation in noisy automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | 8-bit parallel-in/serial-out shift register with complementary outputs |
| Supply Voltage | 2.0 V to 6.0 V - supports wide-range automotive power rails including 3.3 V and 5 V systems |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and powertrain applications |
| Propagation Delay | 15 ns (CP to Q7 @ VCC = 6 V) - enables >35 MHz clock operation for real-time data streaming |
| Input Tolerance | Up to 15 V - permits direct connection to 12 V automotive signals without external clamping |
| Output Drive | ±25 mA - sufficient to drive multiple TTL loads or trace capacitance up to 50 pF |

Pinout & Package
Package: SO16 plastic small outline package (SOT109-1), 16-pin, 3.9 mm body width, surface-mount compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (PL) | Asynchronous parallel load enable | Active-LOW signal that latches D0–D7 immediately into register, independent of clock |
| 2 (CP) | Clock input | LOW-to-HIGH edge-triggered; advances shift register only when CE = LOW |
| 7 (Q7) | True serial output | MSB output after full 8-bit shift; used for daisy-chaining or microcontroller SPI input |
| 9 (Q7) | Inverted serial output | Complementary to Q7; supports differential sensing or noise-immune sampling |
| 10 (DS) | Serial data input | Accepts new bit during shift mode; sampled on CP rising edge when CE = LOW |
| 11–14, 3–6 (D0–D7) | Parallel data inputs | 8-bit wide bus for fast parallel capture; mapped directly to register stages |
| 15 (CE) | Clock enable | Active-LOW gate for CP - disables shifting when HIGH, preserving register state |
| 16 (VCC) | Positive supply | Primary power rail; decoupling required within 10 mm for stable high-speed operation |
| 8 (GND) | Ground reference | Signal and power return path; must be low-impedance to minimize ground bounce |

Use Value: Provides fail-safe pre-CAN health check using only 3 MCU pins and no additional ICs or firmware overhead. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit parallel-in/serial-out shift register applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT165D-Q100 | TTL-compatible inputs (VIH = 2.0 V min), slightly higher propagation delay (17 ns @ 4.5 V) | Better suited for mixed 5 V TTL/CMOS systems where input thresholds must match legacy logic | Select when interfacing with older 5 V microcontrollers or logic families requiring 2 V VIH |
| SN74LV165AQPWRQ1 | Lower VCC range (1.65–5.5 V), higher fmax (60 MHz @ 5 V), but no overvoltage tolerance | Preferred for low-voltage automotive modules (e.g., 3.3 V ADAS subsystems) without 12 V signal exposure | Choose for 3.3 V-only designs needing higher speed and lower power, where 15 V input tolerance is unnecessary |
Compared with 74HC165D-Q100, the 74HCT165D-Q100 offers tighter input threshold compatibility with legacy 5 V systems but sacrifices some speed and voltage margin; the SN74LV165AQPWRQ1 delivers superior speed and low-voltage operation but removes critical overvoltage protection needed in mixed-signal automotive nodes.

FAQ
What is the maximum clock frequency supported by the 74HC165D-Q100?
The 74HC165D-Q100 supports up to 35 MHz at VCC = 6.0 V and 20 MHz at VCC = 4.5 V under recommended operating conditions. Measured fmax is defined with CL = 50 pF and accounts for worst-case propagation delays across the -40 °C to +125 °C temperature range, ensuring reliable timing margin in automotive applications.
Can the 74HC165D-Q100 interface directly with 12 V automotive signals?
Yes - all inputs (PL, CP, CE, DS, D0–D7) are overvoltage tolerant up to 15 V, allowing direct connection to 12 V automotive buses without external level-shifting components. This feature is validated per datasheet Section 1 and enables simplified design in body electronics and lighting control units.
How does the asynchronous parallel load (PL) function interact with ongoing serial shifts?
Asserting PL LOW immediately overwrites the entire 8-bit register with D0–D7 values, regardless of CP or CE state. This action halts any in-progress shift sequence and resets internal stage alignment, making it ideal for synchronized state capture in time-critical automotive subsystems like window lift or seat position sensing.
Is the SO16 package (SOT109-1) lead-free and RoHS compliant?
Yes - the 74HC165D-Q100 in SO16 package is manufactured with lead-free terminations and complies with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Full material declarations and test reports are available through Nexperia's product change notifications and Aetrix Electronics' compliance portal.
