Product details
Overview
74HC165BQ-Q100 from Nexperia is an automotive-qualified 8-bit parallel-in/serial-out shift register with asynchronous parallel load (PL), synchronous serial shift (CP/CE), complementary Q7/Q7 outputs, and overvoltage-tolerant inputs up to 15 V. It operates from -40 °C to +125 °C, supports CMOS-level logic, and enables high-to-low level shifting in automotive body control modules.
For engineers reviewing the 74HC165BQ-Q100 datasheet, 74HC165BQ-Q100 pinout, 74HC165BQ-Q100 application, or 74HC165BQ-Q100 equivalent, key selection criteria include parallel-load latency (14 ns @ 6 V), propagation delay (10–43 ns), DHVQFN16 package compatibility with AOI, AEC-Q100 Grade 1 qualification, and dual-rail input tolerance for mixed-voltage interfacing.
Technical Context
This device implements an 8-stage static shift register with dual-mode data entry: asynchronous parallel load via active-low PL input, and synchronous serial shift controlled by CP (edge-triggered) and CE (active-low enable). The architecture supports both serial-in/serial-out and parallel-in/serial-out configurations without internal latching between stages.
Input voltage thresholds are CMOS-compatible (VIH = 4.2 V min @ VCC = 6 V; VIL = 1.8 V max), and output drive capability meets ±4 mA at 4.5 V with VOL ≤ 0.4 V and VOH ≥ 3.7 V. Overvoltage tolerance (up to 15 V on all inputs) enables direct interfacing with 12 V automotive signals while powered from 5 V rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
DHVQFN16 (SOT763-1) package with 16 terminals, no leads, 2.5 × 3.5 × 0.85 mm body, and side-wettable flanks for AOI-compliant reflow inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (PL) | Asynchronous parallel load control | Active-LOW signal loads D0–D7 into register immediately, independent of clock edges |
| 2 (CP) | Shift clock input | LOW-to-HIGH edge triggers serial shift when CE = LOW; disabled when CE = HIGH |
| 7 (Q7) | Serial output (MSB) | True output of final stage; used for daisy-chaining or microcontroller SPI input |
| 8 (GND) | Ground reference | 0 V return path; thermal pad beneath die must be connected to PCB ground plane for thermal performance |
| 9 (Q7) | Complementary serial output | Inverted Q7 signal; supports differential sensing or noise-immune routing in noisy environments |
| 10 (DS) | Serial data input | Feeds new bit into LSB position during shift cycles; sampled on CP rising edge when CE = LOW |
| 11–14, 3–6 (D0–D7) | Parallel data inputs | Eight independent inputs accepting logic levels simultaneously during PL assertion |
| 15 (CE) | Clock enable | Active-LOW gate for CP; holds register state when HIGH, preventing unintended shifts |
| 16 (VCC) | Positive supply | Primary power rail; decoupling capacitor (100 nF) required within 5 mm of pin for stable switching |

Use Value: 15 V input tolerance allows direct connection to unregulated 12 V sensor supplies, reducing BOM cost by eliminating 8 discrete level shifters. |
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 |
|---|---|---|---|
| 74HCT165BQ-Q100 | TTL-compatible inputs (VIH = 2.0 V min @ 4.5–5.5 V); identical pinout, timing, and package | Required when interfacing with legacy 5 V TTL logic families; not suitable for pure CMOS systems with <2 V logic swings | Select when driving from 5 V microcontrollers or logic with marginal VIH margins; otherwise prefer HC version for lower static power and wider VCC range |
| SN74LV165AQPWRQ1 | Lower VCC range (1.65–5.5 V), higher fmax (125 MHz), but no overvoltage tolerance or Q7 complement output | Suitable for low-voltage ADAS SoCs but requires external clamping for 12 V sensor interfaces and lacks noise-immune differential output | Choose for high-speed serial throughput in 3.3 V domains; avoid where 15 V input tolerance or Q7 inversion is needed for EMC robustness |
Compared with 74HCT165BQ-Q100, the HC variant offers broader supply flexibility and lower ICC, while SN74LV165AQPWRQ1 trades overvoltage protection for speed and low-voltage operation-making the 74HC165BQ-Q100 optimal for cost-sensitive, mixed-voltage automotive I/O expansion where robustness and pin compatibility are prioritized.

FAQ
What is the maximum clock frequency supported by the 74HC165BQ-Q100?
The 74HC165BQ-Q100 supports a maximum clock frequency of 24 MHz at VCC = 6.0 V and -40 °C to +125 °C, based on worst-case propagation delay (43 ns) and setup/hold timing margins. At 4.5 V, fmax is 20 MHz; at 2.0 V, it drops to 4 MHz. These values assume CL = 50 pF and proper PCB layout with local decoupling.
Can the 74HC165BQ-Q100 interface directly with 12 V automotive sensors?
Yes - all digital inputs (PL, CP, CE, DS, D0–D7) tolerate up to 15 V regardless of VCC level, enabling direct connection to 12 V switch banks, potentiometers, or sensor outputs without external level-shifting components. This is verified per datasheet Section 1 and Table 4 limiting values.
How does the DHVQFN16 package improve manufacturability versus SO16 or TSSOP16?
The DHVQFN16 (SOT763-1) package features side-wettable flanks that allow automated optical inspection (AOI) of solder joint quality on all 16 terminals - unlike SO16 or TSSOP16, which require X-ray for hidden lead inspection. Its 0.85 mm height also reduces board space and improves thermal resistance (11.2 mW/K derating above 106 °C).
Is the Q7 output truly complementary to Q7, or is it inverted logic only?
Q7 and Q7 are electrically complementary outputs - they are driven by separate output stages with opposite polarity, providing true differential signaling capability. Measured propagation delays differ by ≤0.5 ns (per Fig. 7), confirming matched timing essential for noise rejection in automotive EMI environments.
