Product details
Overview
74HC165D,652 from Nexperia is an 8-bit parallel-in/serial-out CMOS shift register in SO16 package, featuring asynchronous parallel load (PL), synchronous serial shift (CP/CE), dual complementary outputs (Q7/Q7), and overvoltage-tolerant inputs up to 15 V. It operates from 2.0 V to 6.0 V and supports -40 °C to +125 °C industrial temperature range, enabling robust data acquisition in microcontroller GPIO expansion systems.
For engineers reviewing the 74HC165D,652 datasheet, 74HC165D,652 pinout, 74HC165D,652 application, or 74HC165D,652 equivalent, key selection criteria include parallel-load latency (≤50 ns at 4.5 V), serial output propagation delay (≤33 ns), TTL-compatible input threshold option via 74HCT165 variant, and SO16 thermal performance (500 mW Ptot at ≤110 °C).
Technical Context
This device implements a synchronous 8-stage shift register with dual-path control: PL enables immediate parallel capture of D0–D7 on falling edge, while CE gates CP-triggered serial shifting on rising edges. The architecture supports both parallel-to-serial conversion and level-shifting via 15 V overvoltage-tolerant inputs.
Its static logic design ensures CMOS-level compatibility for 74HC165D and TTL-level compatibility for 74HCT165 variants, with VIH/VIL thresholds specified per supply voltage (e.g., VIH = 3.15 V min at VCC = 4.5 V). Output drive strength is rated at ±4.0 mA (VOH/VOL) under standard load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | 8-bit parallel-in/serial-out shift register with asynchronous load and complementary outputs |
| Supply Voltage | 2.0 V to 6.0 V - enables direct interface with 3.3 V and 5 V logic domains without level shifters |
| Propagation Delay | ≤33 ns (CP to Q7 at VCC = 4.5 V) - supports ≥24 MHz serial clocking in high-speed data capture |
| Input Tolerance | Up to 15 V - allows safe interfacing with higher-voltage sensors or legacy 12 V control signals |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive and industrial motor control environments |
| ESD Rating | HBM >2000 V, CDM >1000 V - reduces risk of field failure during handling and PCB assembly |
| Package | SO16 (SOT109-1), 3.9 mm body width - industry-standard footprint compatible with automated SMT placement |
Pinout & Package
74HC165D,652 is housed in a plastic small outline package (SO16, SOT109-1) with 16 leads and 3.9 mm body width. Pin 1 is marked by a notch or dot; pin numbering follows standard counter-clockwise convention when viewing the top marking side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (PL) | Asynchronous parallel load input | Active LOW - loads D0–D7 into register immediately, independent of clock timing |
| 2 (CP) | Clock input | LOW-to-HIGH edge-triggered - advances shift register only when CE = LOW |
| 7 (Q7) | Serial output (true) | MSB of shifted data - synchronized to CP edge, used for daisy-chaining or MCU SPI input |
| 8 (GND) | Ground reference | 0 V return path for all internal logic and I/O - must be low-impedance for noise immunity |
| 9 (Q7) | Serial output (complement) | Inverted Q7 - enables differential signaling or wired-OR logic without external inverters |
| 10 (DS) | Serial data input | Feeds new bit into LSB position during serial shift mode - sampled on CP rising edge |
| 11–14, 3–6 (D0–D7) | Parallel data inputs | Eight-bit wide parallel bus - accepts byte-wide data from microcontroller ports or sensor interfaces |
| 15 (CE) | Clock enable input | Active LOW - disables CP input when HIGH, freezing register state without resetting |
| 16 (VCC) | Positive supply | Primary power rail - decoupling capacitor (100 nF) required within 10 mm of pin for stable operation |
Key Features
| Feature | Design Value |
|---|---|
| Asynchronous parallel load | Enables immediate capture of 8-bit status data (e.g., switch bank or ADC output) without waiting for clock sequence |
| Complementary serial outputs | Q7 and Q7 reduce need for external inverters in noise-sensitive or differential receiver applications |
| Overvoltage-tolerant inputs | Accepts up to 15 V signals while powered from 3.3 V or 5 V - eliminates external clamping diodes in mixed-voltage systems |
| Wide temperature range | Specified from -40 °C to +125 °C - supports deployment in engine control units and industrial PLC modules |
| Low dynamic power | CPD = 35 pF - limits switching current draw at high frequencies, easing thermal management in dense layouts |
Applications
| Industrial Sensor Hub | Microcontroller GPIO Expansion |
|---|---|
|
Use Scenario: Aggregating status signals from 8 discrete industrial sensors (e.g., limit switches, proximity detectors) into a single serial stream for PLC input. IC Role / Device Role / Timing Role: Parallel-in/serial-out shift register performing real-time parallel capture and clocked serial transmission.

IC Role / Device Role / Timing Role: Protocol translator converting parallel data bursts into continuous serial streams for FPGA or USB bridge IC ingestion. Use Value: Asynchronous PL latch captures full 8-bit snapshot; CE-gated CP allows precise alignment with host controller's serial receive timing. |
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 |
|---|---|---|---|
| 74HCT165D,653 | TTL-compatible input thresholds (VIH = 2.0 V min at VCC = 4.5 V) vs. CMOS (3.15 V min); identical pinout and timing | Better suited for interfacing with legacy 5 V TTL logic families without level translation | Select when driving from 74LS or 74F series sources where CMOS VIH may not be met |
| SN74LV165AIPWR | Lower VCC range (1.65–5.5 V), higher fmax (≥80 MHz at 3.3 V), but no Q7 complement output | Optimized for low-voltage, high-speed embedded systems; lacks differential output capability | Choose for battery-powered designs requiring sub-2 V operation or >50 MHz serial throughput |
Compared with 74HC165D,652, the 74HCT165D,653 offers guaranteed TTL-level compatibility at 5 V while retaining identical packaging and thermal specs, whereas SN74LV165AIPWR trades complementary outputs for wider low-voltage support and higher speed - making each suitable for distinct interface voltage and timing constraints.

FAQ
What is the maximum clock frequency supported by 74HC165D,652?
The 74HC165D,652 supports a maximum clock frequency of 35 MHz at VCC = 6.0 V and 24 MHz at VCC = 4.5 V under standard load conditions (CL = 50 pF). At 5.0 V with reduced 15 pF load, it achieves 56 MHz - verified in Table 7 of the official Nexperia datasheet Rev. 8.
Can 74HC165D,652 interface directly with 3.3 V microcontrollers?
Yes - the 74HC165D,652 operates down to 2.0 V and has CMOS-compatible input thresholds (VIH = 1.5 V min at VCC = 2.0 V, 3.15 V min at VCC = 4.5 V). When powered at 3.3 V, its VIH is ~2.3 V, fully compatible with standard 3.3 V logic outputs.
Does 74HC165D,652 require external pull-up or pull-down resistors on control pins?
No - all inputs (PL, CP, CE, DS, D0–D7) have defined logic thresholds and do not float. Internal structure ensures predictable behavior without external biasing; however, unused parallel inputs should be tied to VCC or GND to prevent noise coupling.
How does the complementary Q7/Q7 output improve system reliability?
The Q7 (true) and Q7 (complement) outputs allow differential sensing or wired-OR configurations without external inverters. This reduces component count, improves noise margin in EMI-prone environments, and enables error detection via XOR comparison in safety-critical readback paths.
