Product details
Overview
74LV165AD-Q100 from Nexperia is an automotive-qualified 8-bit parallel-in/serial-out shift register with complementary Q7/Q7 outputs, asynchronous parallel load (PL active LOW), synchronous serial shift on CP rising edge, and gate-OR clock input supporting CE as active-LOW clock enable. It operates from 2.0 V to 5.5 V across −40 °C to +85 °C and supports TTL-level interfacing in automotive body control modules.
For engineers reviewing the 74LV165AD-Q100 datasheet, 74LV165AD-Q100 pinout, 74LV165AD-Q100 application, or 74LV165AD-Q100 equivalent, key selection criteria include its AEC-Q100 Grade 3 qualification, IOFF power-down protection, Schmitt-trigger inputs for noise immunity, 5.5 V-tolerant I/O, and SO16 package compatibility with legacy PCB layouts.
Technical Context
This device implements an 8-stage static CMOS shift register with dual-mode data entry: parallel load (asynchronous, PL=LOW) and serial shift (synchronous, CP rising edge). The gate-OR clock structure allows flexible assignment of CP and CE pins, with CE requiring HIGH-to-LOW transitions only while CP is HIGH for deterministic operation.
It features Schmitt-trigger inputs for robust handling of slow-rising signals, IOFF circuitry enabling safe partial power-down by disabling outputs and preventing backflow current, and complementary serial outputs (Q7 and Q7) enabling daisy-chained expansion without external inverters in serial-data pipelines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | 8-bit parallel-in/serial-out shift register with complementary Q7/Q7 outputs |

Pinout & Package
74LV165AD-Q100 is housed in a plastic small outline package (SO16, SOT109-1) with 16 leads and 3.9 mm body width, optimized for automated assembly and thermal reliability in automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (PL) | Parallel load enable | Active-LOW asynchronous control: loads D0–D7 into register regardless of clock state |
| 2 (CP) | Clock input | Rising-edge triggered; gate-OR'd with CE to allow CE-as-enable functionality |
| 7 (Q7) | Serial output | MSB serial output; shifts right (Q0→Q1→…→Q7) on each CP rising edge |
| 8 (GND) | Ground reference | 0 V return path for all internal logic and I/O; must be low-impedance in automotive harness designs |
| 9 (Q7) | Complementary serial output | Inverted Q7 - eliminates need for external inverter when cascading multiple stages |
| 10 (DS) | Serial data input | Feeds new bit during serial shift mode; tied to Q7 of upstream device for expansion |
| 11–14, 3–6 (D0–D7) | Parallel data inputs | 8-bit wide parallel bus; sampled asynchronously when PL = LOW |
| 15 (CE) | Clock enable | Active-LOW; gating function allows clock suspension without stopping CP source |
| 16 (VCC) | Positive supply | 2.0–5.5 V primary power rail; powers all logic and output drivers |

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 |
|---|---|---|---|
| SN74LV165AQPWRQ1 | TSSOP16 (SOT403-1) package; identical electrical specs and AEC-Q100 Grade 3 rating | Smaller footprint (4.4 mm width) and lower profile - preferred for space-constrained ADAS camera modules | Select when board area is constrained and reflow compatibility with fine-pitch components is required. |
| 74LVC164APW-Q100 | 8-bit serial-in/serial-out only (no parallel load); same SO16 package and AEC-Q100 Grade 3 | Lacks PL input - unsuitable for snapshot capture but simpler for pure serial chain expansion | Choose only if application requires unidirectional serial chaining without parallel initialization capability. |
Compared with SN74LV165AQPWRQ1, the 74LV165AD-Q100 offers identical functionality in a wider SO16 package better suited for manual inspection and wave soldering in body electronics; versus 74LVC164APW-Q100, it provides essential parallel-load capability for time-critical sensor snapshotting absent in pure SIPO architectures.

FAQ
Can 74LV165AD-Q100 operate reliably at 2.0 V supply?
Yes. The device is fully specified down to 2.0 V supply voltage, with guaranteed propagation delays ≤24 ns and VIH/VIL thresholds scaled to 0.7×VCC and 0.3×VCC respectively. At 2.0 V, it delivers 1.5 V VIH minimum and 0.5 V VIL maximum, enabling interoperability with 1.8 V–2.5 V microcontrollers in ultra-low-power automotive modules.
What is the purpose of the gate-OR clock structure between CP and CE?
The gate-OR architecture allows either pin to serve as clock input while the other acts as active-LOW enable - eliminating need for external gating logic. This enables layout flexibility (pin swap allowed) and ensures predictable behavior: CE must transition LOW only while CP is HIGH to avoid metastability in the clock path.
How does IOFF protection function during power-down sequences?
When VCC drops to 0 V, the IOFF circuit disables all outputs and presents high-impedance I/O states, limiting back-current to ±5 μA maximum. This prevents reverse current flow from powered downstream circuits (e.g., 5 V sensor buses) into the unpowered shift register - a critical requirement for ISO 16750-2 compliant automotive power cycling.
Is the 74LV165AD-Q100 compatible with standard 5 V TTL logic levels?
Yes. Its 5.5 V-tolerant inputs accept 2.7 V–3.6 V TTL voltage levels directly, and VOH/VOL specifications guarantee 2.48 V min high output and 0.44 V max low output at 3.0 V VCC with 6 mA load - meeting TTL switching thresholds without level-shifting circuitry in mixed-voltage automotive networks.
