Product details
Overview
74LV165PW-Q100 from Nexperia is an automotive-grade 8-bit parallel-in/serial-out shift register with asynchronous parallel load, dual complementary serial outputs (Q7 and Q7), and clock enable control. It operates from 1.0 V to 5.5 V, supports -40 °C to +125 °C ambient range, and features CMOS low-power operation with TTL-level compatibility at 2.7 V–3.6 V. It is used in automotive body control modules for LED driver expansion and sensor data consolidation.
For engineers reviewing the 74LV165PW-Q100 datasheet, 74LV165PW-Q100 pinout, 74LV165PW-Q100 application, or 74LV165PW-Q100 equivalent, key selection considerations include its AEC-Q100 Grade 1 qualification, dual-output timing alignment, parallel-load latency (as low as 14 ns at 3.3 V), and TSSOP16 package suitability for space-constrained PCB layouts in ADAS domain controllers and gateway ECUs.
Technical Context
This shift register implements an 8-stage static CMOS shift register with edge-triggered clock (CP) and active-low parallel load (PL) enabling immediate capture of 8-bit parallel inputs without clock dependency. Its dual serial outputs (Q7 and Q7) provide synchronized inverted/non-inverted data streams for differential signaling or redundancy checking in safety-critical paths.
The device uses a synchronous serial-shift mode when PL is HIGH and CE is LOW, shifting data on each LOW-to-HIGH CP transition; CE HIGH blocks clock propagation entirely. Input clamp diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors - a critical feature for mixed-voltage automotive subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
TSSOP16 plastic thin shrink small outline package (SOT403-1); 16 leads; body width 4.4 mm; lead pitch 0.65 mm; moisture sensitivity level MSL3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - PL | Parallel load enable input | Active-LOW asynchronous latch control: loads D0–D7 directly into register regardless of clock state |
| 2 - CP | Clock input | LOW-to-HIGH edge-triggered shift clock; disabled when CE = HIGH |
| 7 - Q7 | Serial output (non-inverted) | MSB serial output after full 8-bit shift; aligned with Q7 for timing validation |
| 8 - GND | Ground reference | 0 V return path for all internal logic and output drivers; requires low-impedance PCB plane |
| 9 - Q7 | Serial output (inverted) | Complementary output to Q7; enables noise-immune differential sampling or fault detection |
| 10 - DS | Serial data input | Data entered during serial-shift mode (PL = HIGH, CE = LOW); sampled on CP rising edge |
| 11–14, 3–6 - D0–D7 | Parallel data inputs | 8-bit wide parallel bus; latched simultaneously on PL falling edge; no setup/hold required relative to PL |
| 15 - CE | Clock enable input | Active-LOW gate for CP: CE = HIGH freezes register state and prevents spurious shifts |
| 16 - VCC | Positive supply voltage | Single-supply rail supporting 1.0–5.5 V; decoupling capacitor (100 nF) required within 5 mm of pin |
Key Features

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LV165AQPWRQ1 | TI variant with identical pinout and AEC-Q100 Grade 1 rating; max fmax = 65 MHz at 3.3 V (vs. 78 MHz) | Limited to lower-speed daisy chains; lacks Q7/Q7 dual-output timing alignment spec | Select when TI ecosystem alignment or existing schematic reuse outweighs 17% speed penalty and differential output need |
| 74LVC164APW-Q100 | Nexperia serial-in/serial-out (SIPO) only; no parallel load; 1.65–3.6 V VCC range; no Q7/Q7 complement | Suitable only for pure serial expansion; cannot replace parallel-capture functions in sensor interfaces | Choose only for cost-sensitive non-automotive designs where parallel input is unnecessary and VCC ≤ 3.6 V |

FAQ
What is the minimum VCC required for guaranteed operation at 125 °C?
The 74LV165PW-Q100 guarantees full functionality down to 1.0 V across its entire -40 °C to +125 °C operating range, as confirmed in Table 5 (Recommended Operating Conditions). At 125 °C, static parameters including VIH (min 0.9 V at VCC = 1.2 V) and VOL (max 0.2 V at IO = 6 mA) remain within specification, enabling reliable use in 1.2 V domain microcontrollers even under thermal stress.
Can Q7 and Q7 be used simultaneously to drive separate loads?
Yes - Q7 and Q7 are electrically isolated complementary outputs with matched propagation delays (≤1 ns skew per datasheet Fig. 6). Each drives standard CMOS loads up to ±25 mA, allowing independent connection to separate optocouplers, comparators, or differential receivers without signal degradation or timing mismatch.
Is the PL input truly asynchronous, and does it require setup time relative to other signals?
Yes - PL is fully asynchronous: loading D0–D7 occurs immediately upon PL transition to LOW, with no dependency on CP or CE state. Table 3 confirms "L X X X" entries show parallel load execution regardless of clock or enable levels, and Figure 7 shows no setup requirement between Dn and PL - eliminating timing constraints in interrupt-driven capture scenarios.
How does the input clamp diode feature protect against overvoltage, and what resistor value is recommended?
The integrated clamp diodes connect each input to VCC and GND. When interfacing to voltages > VCC (e.g., 12 V wake line), a series current-limiting resistor restricts diode current to <20 mA (per Table 4 IIK limit). For 12 V input and 3.3 V VCC, a 470 Ω resistor limits peak current to ~18.5 mA - satisfying absolute maximum ratings while enabling direct mixed-voltage interfacing.
