Product details
Overview
74LV165D-Q100 from Nexperia is an automotive-qualified 8-bit parallel-in/serial-out shift register with asynchronous parallel load (PL), dual complementary serial outputs (Q7 and Q7), clock enable (CE), and wide 1.0 V to 5.5 V supply operation. It supports synchronous serial shifting on rising-edge CP, operates from −40 °C to +125 °C, and is used in automotive body control modules for GPIO expansion and LED driver interface.
For engineers reviewing the 74LV165D-Q100 datasheet, 74LV165D-Q100 pinout, 74LV165D-Q100 application, or 74LV165D-Q100 equivalent, key selection considerations include its AEC-Q100 Grade 1 qualification, dual-output capability for differential sensing, low-voltage compatibility down to 1.0 V, and SO16 package suitability for high-reliability PCB layouts.
Technical Context
This device implements an 8-stage CMOS shift register with independent parallel-load and serial-shift paths controlled by PL and CE. Its asynchronous parallel load allows immediate capture of D0–D7 inputs when PL is LOW, while CE gating enables precise clock domain isolation during serial shifting on CP's rising edge.
The dual complementary outputs Q7 and Q7 support noise-immune signal transmission and direct connection to differential receivers or logic comparators. Clamp diodes on all inputs permit safe interfacing with voltages exceeding VCC when current-limiting resistors are used - a critical feature for mixed-voltage automotive subsystems.
Key Specifications

| Function | 8-bit parallel-in/serial-out shift register with asynchronous load and dual complementary outputs |
| Supply Voltage Range | 1.0 V to 5.5 V - enables direct interface with 1.2 V, 1.8 V, 3.3 V, and 5 V logic domains |
| Operating Temperature | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive use |
| Propagation Delay (tpd) | 14 ns typical at VCC = 4.5–5.5 V - supports >30 MHz clock rates in high-speed serial chains |

Pinout & Package
74LV165D-Q100 uses the SOT109-1 (SO16) plastic small outline package: 16-pin, 3.9 mm body width, 1.27 mm pitch, gull-wing leads. Pin 1 is marked with a notch or dot; pin numbering follows standard counter-clockwise convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (PL) | Parallel Load Enable | Active-LOW asynchronous control: loads D0–D7 into register immediately when asserted |
| 2 (CP) | Clock Input | Rising-edge triggered; advances shift register only when CE = LOW |
| 7 (Q7) | Serial Output | True output from final flip-flop stage; drives downstream logic or shift chain |
| 9 (Q7) | Complementary Serial Output | Inverted version of Q7; enables differential signaling or XOR-based error detection |
| 10 (DS) | Serial Data Input | Feeds new bit into LSB position during serial shift mode (PL = HIGH) |
| 11–14, 3–6 (D0–D7) | Parallel Data Inputs | 8-bit parallel bus; sampled asynchronously on PL assertion |
| 15 (CE) | Clock Enable | Active-LOW gate: blocks CP transitions from affecting register when HIGH |
| 16 (VCC) | Positive Supply | 1.0–5.5 V tolerant; powers all internal logic and output drivers |
| 8 (GND) | Ground Reference | 0 V return path for all I/O and internal circuitry; must be low-impedance |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use across −40 °C to +125 °C ambient, including thermal cycling and humidity testing |
| Dual complementary serial outputs | Q7 and Q7 provide inherent noise rejection and simplify interface to differential receivers or fault-monitoring circuits |
| Wide 1.0 V to 5.5 V supply range | Eliminates level-shifting in multi-rail systems (e.g., 1.2 V MCU core + 5 V sensor interface) |
| Input clamp diodes with current limiting | Enables direct connection to 12 V automotive buses via series resistors without external protection components |
| Synchronous serial input expansion | Multiple devices can be daisy-chained via DS→Q7 to build longer shift registers without additional control lines |
Applications
| Automotive Body Control Unit | LED Driver Interface |
|---|---|
|
Use Scenario: Centralized control of door locks, window lifts, and interior lighting via microcontroller with limited GPIO. IC Role / Device Role / Timing Role: Parallel-to-serial converter that expands MCU output capability using SPI-like timing on CP/PL/CE.

Use Scenario: Driving segmented LED arrays in instrument clusters where EMI-sensitive analog gauges coexist. IC Role / Device Role / Timing Role: Serial data serializer feeding constant-current LED drivers; Q7/Q7 used for current-sense feedback validation. Use Value: Complementary outputs enable real-time open-circuit detection on each LED segment, improving functional safety compliance. |
| Industrial Sensor Hub | Automotive Diagnostic Port Interface |
|
Use Scenario: Aggregating digital status signals from multiple CAN/LIN nodes onto a single microcontroller input line. IC Role / Device Role / Timing Role: Serial-in/parallel-out shift register configured in reverse (DS-driven, Q7 monitored) for compact status polling. Use Value: Enables 8-node status readback in <1 µs using a single GPIO and timer-capture peripheral - minimizing firmware overhead. |
Use Scenario: Isolating diagnostic communication lines (e.g., UDS over K-Line) from main ECU power domain during sleep mode. IC Role / Device Role / Timing Role: Level-shifting and signal conditioning buffer between 5 V diagnostic tool and 3.3 V ECU UART. Use Value: Clamp diodes and 1.0 V minimum VCC tolerance allow reliable wake-up signaling even during brown-out conditions. |
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 | TI variant with identical pinout and AEC-Q100 Grade 1 rating; propagation delay 18 ns @ 5 V (vs. 14 ns for Nexperia) | Higher static current (160 μA vs. 20 μA typical) limits ultra-low-power always-on diagnostics | Select if TI ecosystem alignment or existing layout reuse is prioritized over minimal tpd and ICC |
| 74LVC164BQ-Q100 | Nexperia 8-bit serial-in/serial-out only (no parallel load); smaller XSON8 package; lacks Q7 complement | Cannot replace parallel-load functionality - unsuitable for GPIO expansion requiring instantaneous state capture | Choose only for pure serial daisy-chain applications where board space is critical and parallel load is unnecessary |
Compared with SN74LV165AQPWRQ1, the 74LV165D-Q100 delivers faster timing and lower quiescent current; versus 74LVC164BQ-Q100, it provides essential parallel-load capability and differential output integrity - making it uniquely suited for automotive control and diagnostics where deterministic initialization and noise resilience are mandatory.

FAQ
What is the maximum clock frequency supported by the 74LV165D-Q100?
The 74LV165D-Q100 supports up to 75 MHz maximum clock frequency at VCC = 5.0 V and −40 °C to +85 °C, and 30 MHz at full AEC-Q100 Grade 1 range (−40 °C to +125 °C). This is confirmed in Table 7 of the Rev. 5 datasheet under fmax, with test conditions specifying CL = 15 pF and VCC = 5.0 V.
Can the 74LV165D-Q100 operate with a 1.2 V supply voltage?
Yes - the 74LV165D-Q100 is fully specified down to 1.0 V supply voltage, with guaranteed operation at 1.2 V across −40 °C to +125 °C. Static and dynamic parameters including VIH/VIL thresholds, propagation delay (115 ns typical), and supply current are explicitly characterized at 1.2 V in Tables 6 and 7.
Does the 74LV165D-Q100 support hot insertion or live swapping?
No - the 74LV165D-Q100 does not include hot-swap protection circuitry. While input clamp diodes allow safe biasing above VCC with current limiting, the device lacks power-on reset, I2C-style bus arbitration, or supply sequencing controls required for true hot-plug operation.
How is the complementary output Q7 used in system-level design?
Q7 provides the logical inverse of Q7 and is electrically isolated - enabling differential signaling, XOR-based error checking, or direct drive of complementary-input comparators. In automotive applications, it is commonly used with Q7 to detect open-load faults in LED strings or verify data integrity in safety-critical shift chains.
