Product details
Overview
74HCT164PW-Q100 from Nexperia is an automotive-grade 8-bit serial-in/parallel-out shift register with TTL-compatible inputs, dual gated serial data inputs (DSA/DSB), asynchronous master reset (MR), and edge-triggered clock (CP) operating from 4.5 V to 5.5 V. It delivers 8 parallel outputs (Q0–Q7), supports −40 °C to +125 °C operation, and is qualified to AEC-Q100 Grade 1 for engine control and body electronics.
For engineers reviewing the 74HCT164PW-Q100 datasheet, 74HCT164PW-Q100 pinout, 74HCT164PW-Q100 application, or 74HCT164PW-Q100 equivalent, this device serves as a robust serial-to-parallel interface in automotive microcontroller I/O expansion, LED driver control, and multiplexed sensor data acquisition where deterministic timing, noise immunity, and automotive reliability are required.
Technical Context
The 74HCT164PW-Q100 implements an 8-stage D-type flip-flop chain with synchronous serial loading and asynchronous reset. Data enters via either DSA or DSB-each acting as an active-HIGH enable for the other-and shifts on the LOW-to-HIGH transition of CP. The MR input forces all Q outputs LOW independently of clock or data state.
Its TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5 V) ensure compatibility with legacy 5 V logic families, while its CMOS output structure provides rail-to-rail drive capability (VOH ≥ 3.98 V, VOL ≤ 0.33 V at IO = ±4 mA) and low static current (ICC ≤ 80 μA over temperature).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | 74HCT - TTL-compatible input thresholds, CMOS output drive, enabling direct interfacing with 5 V microcontrollers and peripherals. |
| Supply Voltage Range | 4.5 V to 5.5 V - Matches standard automotive 5 V rail tolerance; excludes 3.3 V operation unlike HC variants. |
| Operating Temperature | −40 °C to +125 °C - Qualified per AEC-Q100 Grade 1, supporting under-hood and powertrain applications. |
| Propagation Delay (tpd) | 17 ns (typ) to 54 ns (max) at VCC = 4.5 V - Enables reliable 20+ MHz serial clock rates in real-time control loops. |
| Output Drive Strength | ±4.0 mA (VOH/VOL) - Sufficient to directly drive LEDs, small-signal MOSFET gates, or CMOS/TTL inputs without buffering. |
| Input Clamp Diodes | Integrated - Allows safe interface to voltages exceeding VCC when used with external current-limiting resistors. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - Meets stringent automotive ESD requirements per JS-001/JS-002. |
Pinout & Package
TSSOP14 package (SOT402-1): plastic thin shrink small outline, 14 leads, 4.4 mm body width, 0.65 mm pitch, side-wettable flanks for AOI.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - DSA | Serial data input A | Active-HIGH enable for DSB; data entered here shifts into Q0 on next CP rising edge. |
| 2 - DSB | Serial data input B | Active-HIGH enable for DSA; functionally identical to DSA with OR-gated logic for flexible serial source selection. |
| 3–6, 10–13 - Q0–Q7 | Parallel output terminals | Registered outputs reflecting shifted data; Q0 is first bit loaded, Q7 is last; all driven CMOS-compatible. |
| 7 - GND | Ground reference | 0 V return path for supply and signals; decoupling capacitor must be placed adjacent to Pin 7 and Pin 14. |
| 8 - CP | Clock input | Edge-triggered (LOW-to-HIGH); controls shift timing; requires clean, monotonic transitions to avoid metastability. |
| 9 - MR | Master reset | Asynchronous active-LOW; clears all flip-flops immediately, overriding CP and data inputs. |
| 14 - VCC | Positive supply | 4.5–5.5 V nominal; must be bypassed with 100 nF ceramic capacitor near Pin 14 to suppress switching noise. |
Key Features
| Feature | Design Value |
|---|---|
| Dual gated serial inputs | DSA and DSB provide hardware-selectable serial sources without external logic, reducing BOM count in multi-sensor systems. |
| AEC-Q100 Grade 1 qualification | Validated for −40 °C to +125 °C operation with full electrical testing, enabling use in engine control units and transmission modules. |
| Asynchronous master reset | MR forces Q0–Q7 LOW within 11 ns (max) at VCC = 4.5 V, ensuring deterministic startup and fault recovery in safety-critical sequences. |
| TTL-compatible input thresholds | VIH = 2.0 V (min), VIL = 0.8 V (max) at VCC = 4.5 V - eliminates level-shifting when interfacing with legacy 5 V MCUs and discrete logic. |
| Side-wettable flanks (TSSOP) | SOT402-1 package enables automated optical inspection of solder joints, improving manufacturing yield in automotive PCB assembly. |
Applications
| Engine Control Unit (ECU) I/O Expansion | Automotive LED Lighting Driver |
|---|---|

IC Role / Device Role / Timing Role: Output latching buffer isolating MCU from panel ESD events while maintaining fast update rate. Use Value: Integrated input clamp diodes allow direct connection to unbuffered panel traces; HBM > 2000 V rating prevents field failures during service handling. |
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 |
|---|---|---|---|
| 74HC164PW-Q100 | CMOS input thresholds (VIH = 3.15 V min at VCC = 4.5 V); higher noise margin but incompatible with 3.3 V logic driving 5 V rail. | Preferred in mixed-voltage systems where upstream logic operates at 3.3 V with level-shifting, or where higher noise immunity is critical. | Select when interfacing with 3.3 V MCUs using level translators or when operating at VCC = 2.0–6.0 V with wide supply tolerance needs. |
| SN74LV164APW | TI part with LV logic family; VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5 V, but only qualified to industrial temp (−40 °C to +125 °C, non-AEC). | Lacks AEC-Q100 documentation and automotive stress testing; unsuitable for safety-critical or OEM production programs. | Acceptable for prototyping or non-automotive industrial use; not recommended for Tier 1 automotive designs requiring full qualification evidence. |
Compared with 74HC164PW-Q100, the HCT variant ensures seamless integration with legacy 5 V TTL systems, while SN74LV164APW offers pin compatibility but lacks automotive qualification evidence-making 74HCT164PW-Q100 the only option meeting full AEC-Q100 Grade 1 requirements with verified 5 V interface behavior.

FAQ
Can 74HCT164PW-Q100 operate at 3.3 V supply?
No. The 74HCT164PW-Q100 is specified only for 4.5 V to 5.5 V operation per its Recommended Operating Conditions table. At 3.3 V, input thresholds fall outside TTL-compatibility range (VIH would be < 2.0 V), and output drive strength degrades significantly. Use 74HC164PW-Q100 instead for 2.0–6.0 V flexibility, or select a dedicated 3.3 V logic family.
What is the maximum clock frequency supported at 125 °C?
At VCC = 4.5 V and TA = +125 °C, the maximum guaranteed clock frequency is 18 MHz (fmax = 22 MHz min, 18 MHz typical per Table 7). This is derived from the 54 ns maximum propagation delay (tpd) and accounts for worst-case setup/hold margins. For reliable operation above 15 MHz, ensure CP rise/fall times ≤ 6 ns and CL ≤ 50 pF.
How does the dual-input gating (DSA/DSB) function in practice?
DSA and DSB implement an OR-gated enable: data enters only when one input is HIGH and the other is LOW. For example, holding DSB = HIGH disables DSA, allowing DSB to serve as the sole serial input; conversely, DSA = HIGH disables DSB. This enables hardware-selectable data paths-e.g., DSA for primary MCU SPI, DSB for fallback diagnostic port-without external logic.
Is the TSSOP14 package (SOT402-1) lead-free and RoHS compliant?
Yes. The 74HCT164PW-Q100 in SOT402-1 packaging is manufactured with lead-free terminations and complies with EU RoHS Directive 2011/65/EU and JEDEC J-STD-609 Category 3 marking. The "PW" suffix explicitly denotes lead-free, halogen-free, and green-compliant construction per Nexperia's product coding system.
