Product details
Overview
74HC164D-Q100 from Nexperia is an AEC-Q100 Grade 1 qualified 8-bit serial-in/parallel-out shift register with dual gated data inputs (DSA, DSB), asynchronous master reset (MR), and edge-triggered clock (CP). It operates from 2.0 V to 6.0 V across –40 °C to +125 °C and delivers 8 parallel outputs (Q0–Q7) for automotive lighting control and dashboard display expansion.
For engineers reviewing the 74HC164D-Q100 datasheet, 74HC164D-Q100 pinout, 74HC164D-Q100 application, or 74HC164D-Q100 equivalent, key selection considerations include its CMOS-level input compatibility, 34 ns typical propagation delay at 4.5 V, SO14 package with side-wettable flanks, and automotive-grade thermal and ESD robustness (HBM >2000 V, CDM >1000 V).
Technical Context
This device implements an 8-stage positive-edge-triggered shift register with asynchronous active-low master reset. Data enters serially via either DSA or DSB-each serving as a high-enable gate for the other-and shifts on LOW-to-HIGH CP transitions. The internal architecture uses eight cascaded D flip-flops with common clock and reset, enabling deterministic timing behavior under automotive temperature extremes.
Input clamping diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors. The SO14 (SOT108-1) package supports AOI-compatible solder joint inspection, and the device complies with JEDEC JESD8C (2.7–3.6 V) and JESD7A (2.0–6.0 V) standards for logic interoperability and latch-up immunity (>100 mA per JESD78 Class II Level B).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | 74HC series CMOS - ensures low static power (<160 µA ICC max at 125 °C) and high noise immunity in noisy automotive environments. |
| Supply Voltage Range | 2.0 V to 6.0 V - supports direct integration with 3.3 V microcontrollers and 5 V legacy automotive subsystems without level-shifting. |
| Propagation Delay (tpd) | 34 ns typ @ 4.5 V, CL = 50 pF - enables reliable 20+ MHz operation in real-time LED matrix scanning and multiplexed display drivers. |
| Operating Temperature | –40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and instrument cluster applications requiring extended thermal stability. |
| ESD Protection | HBM >2000 V, CDM >1000 V - meets automotive ESD robustness requirements for assembly and field reliability without external protection. |
| Output Drive | ±4.0 mA @ 4.5 V VOH/VOL - sufficient to directly drive LEDs or interface with standard CMOS/TTL loads in control logic chains. |
| Power Dissipation | 500 mW max (SO14), derates linearly above 100 °C - supports sustained operation in thermally constrained ECUs with predictable thermal margin. |
Pinout & Package
74HC164D-Q100 is housed in a plastic small outline package (SO14, SOT108-1) with 14 leads, 3.9 mm body width, and side-wettable flanks for automated optical inspection of solder joints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (DSA) | Serial data input A | Gated enable path: HIGH enables data entry via DSB; LOW blocks DSB regardless of DSB state. |
| 2 (DSB) | Serial data input B | Gated enable path: HIGH enables data entry via DSA; LOW blocks DSA regardless of DSA state. |
| 3–6, 10–13 (Q0–Q7) | Parallel output bits | Q0 is LSB, Q7 is MSB; all outputs are push-pull CMOS with rail-to-rail swing and ±4 mA drive capability. |
| 7 (GND) | Ground reference | 0 V return path for all internal logic and I/O; must be low-impedance for stable timing and noise rejection. |
| 8 (CP) | Clock input | Edge-triggered: data shifts on LOW-to-HIGH transition; requires minimum 5 ns pulse width at 6.0 V. |
| 9 (MR) | Master reset | Asynchronous active-LOW: forces all Q outputs LOW immediately, independent of CP or data inputs. |
| 14 (VCC) | Positive supply | Primary power rail (2.0–6.0 V); decoupling capacitor (100 nF) recommended within 5 mm of this pin. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit serial-in/parallel-out shift register applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT164D-Q100 | TTL-compatible inputs (VIH = 2.0 V min), identical timing and packaging | Better suited for mixed-signal systems with 5 V TTL microcontrollers or legacy logic families | Select when interfacing with 5 V TTL outputs; otherwise 74HC164D-Q100 offers wider VCC flexibility and lower input threshold. |
| SN74HC164QPWRQ1 | TI's AEC-Q100 Grade 1 variant in TSSOP-14 (SOT402-1), same electrical specs | Smaller footprint and higher density layout; no side-wettable flanks for AOI | Choose for space-constrained PCBs where AOI is not mandated; SO14 remains preferred for production testability. |
Compared with 74HCT164D-Q100, the 74HC164D-Q100 provides broader supply voltage support (2.0–6.0 V vs. 4.5–5.5 V) and CMOS input thresholds, while SN74HC164QPWRQ1 trades SO14's AOI capability for smaller board area-making the original optimal for cost-sensitive, high-yield automotive manufacturing.

FAQ
Can 74HC164D-Q100 operate at 3.3 V supply?
Yes. The 74HC164D-Q100 is fully specified from 2.0 V to 6.0 V, including 3.3 V operation. At VCC = 3.3 V, VIH is guaranteed ≥2.1 V and VOL ≤0.26 V at 4 mA sink, ensuring reliable interfacing with 3.3 V microcontrollers and FPGAs without level shifters.
What is the function of the dual data inputs DSA and DSB?
DSA and DSB are gated serial inputs: asserting one HIGH enables data entry through the other input, while asserting both HIGH shifts data from whichever input is driven. This allows hardware-selectable data source routing-e.g., DSA for primary MCU data and DSB for diagnostic override signals-without external logic gates.
Does the master reset (MR) pin require a pull-up resistor?
Yes. MR is active LOW and internally unconnected; a 10 kΩ pull-up to VCC is required for normal operation to prevent unintended reset. During power-up, MR must remain HIGH until VCC stabilizes to avoid metastable output states-designs should coordinate MR release with power-good sequencing.
Is the SO14 package of 74HC164D-Q100 compatible with reflow soldering per J-STD-020?
Yes. The SOT108-1 package is qualified for standard lead-free reflow profiles (peak 260 °C, 20–40 s above 217 °C). Its side-wettable flanks support post-reflow AOI verification of solder fillet geometry on all 14 leads, meeting IPC-A-610 Class 2/3 requirements for automotive production.
