Product details
Overview
74HCT165PW-Q100 from Nexperia is an automotive-grade 8-bit parallel-in/serial-out shift register with TTL-compatible inputs, asynchronous parallel load (PL), complementary serial outputs (Q7 and Q7), and clock enable (CE) control. It operates from -40 °C to +125 °C, supports 4.5–5.5 V supply, and delivers 26 MHz max clock frequency at VCC = 4.5 V - used in automotive body control modules for GPIO expansion via SPI-compatible serial interfaces.
For engineers reviewing the 74HCT165PW-Q100 datasheet, 74HCT165PW-Q100 pinout, 74HCT165PW-Q100 application, or 74HCT165PW-Q100 equivalent, key selection factors include its AEC-Q100 Grade 1 qualification, dual-output timing symmetry (tpd ≤ 43 ns), overvoltage-tolerant inputs (up to 15 V), TSSOP16 package with side-wettable flanks for AOI, and compatibility with legacy 5 V TTL logic systems.
Technical Context
This device implements a synchronous 8-stage shift register with asynchronous parallel load capability. Its functional architecture allows simultaneous capture of 8-bit parallel data on PL low, followed by serial shifting on CP rising edges when CE is low - enabling deterministic latency control in time-critical automotive subsystems.
The dual complementary outputs (Q7 and Q7) provide matched propagation delays (≤ 43 ns at VCC = 4.5 V) and transition times (≤ 22 ns), while input overvoltage tolerance (15 V) permits robust level-shifting between higher-voltage sensors and 5 V microcontroller domains without external protection circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5–5.5 V - ensures stable operation across automotive battery transients (e.g., cold-crank down to 4.5 V). |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and powertrain applications. |
| Max Clock Frequency | 26 MHz at VCC = 4.5 V - supports high-throughput serial data acquisition from multiple sensors. |
| Propagation Delay | ≤ 43 ns (CP/Q7, PL/Q7) - guarantees sub-50 ns deterministic latency for real-time control loops. |
| Input Voltage Levels | TTL-compatible VIH ≥ 2.0 V, VIL ≤ 0.8 V - interoperable with legacy 5 V microcontrollers and peripheral ICs. |
| Output Drive | VOH ≥ 3.7 V @ IO = -4.0 mA, VOL ≤ 0.4 V @ IO = 5.2 mA - sufficient fanout for driving multiple CMOS/TTL inputs. |
| ESD Protection | HBM > 2000 V, MM > 200 V - meets automotive ESD immunity requirements for assembly and field operation. |
Pinout & Package
TSSOP16 plastic thin shrink small outline package (SOT403-1); 16 leads; body width 4.4 mm; side-wettable flanks for automated optical inspection of solder joints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (PL) | Asynchronous parallel load input | Active-LOW signal that latches D0–D7 into register immediately - enables instant state capture independent of clock. |
| 2 (CP) | Clock input | LOW-to-HIGH edge-triggered; controls serial shift timing - synchronized with system master clock domain. |
| 7 (Q7) | Serial output | MSB output after 8 shifts; drives downstream logic or microcontroller MISO line directly. |
| 9 (Q7) | Complementary serial output | Inverted Q7 signal - supports differential sensing or noise-immune routing in noisy automotive environments. |
| 10 (DS) | Serial data input | Accepts serial data 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 loading sensor status, switch states, or configuration bits in one cycle. |
| 15 (CE) | Clock enable input | Active-LOW gate for CP - halts shifting without clock gating, preserving internal state during idle periods. |
| 16 (VCC) | Positive supply | 5 V nominal rail; decoupling required within 10 mm for stable switching performance. |
| 8 (GND) | Ground reference | 0 V return path; must be low-impedance connection to minimize ground bounce in multi-stage daisy chains. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient - eliminates need for additional qualification testing in Tier 1 designs. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC165PW-Q100 | CMOS input thresholds (VIH ≥ 3.15 V @ VCC = 4.5 V); lower ICC (8 μA typical) but incompatible with TTL logic levels. | Suitable only where driving source is CMOS-compatible; not recommended for legacy 5 V TTL systems. | Select when system uses pure CMOS logic and ultra-low static current is critical - not for mixed-signal or TTL-interfaced designs. |
| SN74LV165APWR | Lower voltage range (2–5.5 V); LV logic family; no AEC-Q100 qualification; 32 MHz fmax at 5 V. | Targeted at industrial/commercial applications; lacks automotive temperature range and qualification documentation. | Choose for cost-sensitive non-automotive designs requiring wider VCC range or higher speed - not for automotive production programs. |

FAQ
What is the maximum clock frequency supported by the 74HCT165PW-Q100?
The 74HCT165PW-Q100 supports a maximum clock frequency of 26 MHz at VCC = 4.5 V and -40 °C to +125 °C ambient. At 5.0 V and CL = 15 pF, the datasheet specifies 48 MHz - but this higher value applies only under controlled lab conditions and is not guaranteed across the full automotive temperature range.
Can the 74HCT165PW-Q100 interface directly with 12 V sensors?
Yes - all inputs are overvoltage tolerant up to 15 V, allowing direct connection to 12 V automotive sensor outputs without external clamping diodes or level-shifters. This capability is validated across the full -40 °C to +125 °C operating range and is part of its AEC-Q100 qualification test plan.
Does the 74HCT165PW-Q100 require external pull-up or pull-down resistors on control pins?
No - the PL, CE, and CP inputs have no internal pull resistors, but their DC input leakage current is ≤ ±1 μA across temperature, so external biasing is only needed if signal sources are high-impedance or floating. In standard 5 V CMOS/TTL driving configurations, no external resistors are required.
How does the complementary Q7 and Q7 output functionality improve noise immunity?
The matched propagation delay (≤ 43 ns) and transition time (≤ 22 ns) between Q7 and Q7 enable differential signaling techniques - such as XOR-based clock/data recovery or common-mode noise rejection - without external components. This reduces susceptibility to EMI in high-noise automotive harness environments.
