Product details
Overview
74HCT164D-Q100 from Nexperia is an AEC-Q100 Grade 1 qualified 8-bit serial-in/parallel-out shift register with gated dual data inputs (DSA, DSB), asynchronous master reset (MR), and edge-triggered clock (CP). It operates from 4.5 V to 5.5 V, delivers TTL-compatible input thresholds, supports −40 °C to +125 °C ambient range, and drives eight buffered CMOS outputs (Q0–Q7) for automotive body control modules requiring reliable serial-to-parallel expansion.
For engineers reviewing the 74HCT164D-Q100 datasheet, 74HCT164D-Q100 pinout, 74HCT164D-Q100 application, or 74HCT164D-Q100 equivalent, this device serves as a robust serial-to-parallel interface in space-constrained automotive PCBs where deterministic timing, noise immunity, and automotive-grade reliability are mandatory - not a generic logic IC.
Technical Context
The 74HCT164D-Q100 implements an 8-stage positive-edge-triggered shift register with synchronous serial data loading via two independently gated inputs. Data entered at DSA or DSB propagates through eight flip-flops on each LOW-to-HIGH CP transition, with either input acting as an active-HIGH enable for the other.
Its asynchronous MR input forces all Q outputs LOW independent of CP or data state, enabling immediate register clearing. Input clamp diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors - a key requirement for mixed-voltage automotive signal conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | 8-bit serial-in/parallel-out shift register with dual gated data inputs and asynchronous reset |
| Supply Voltage | 4.5 V to 5.5 V - matches standard automotive 5 V rail with ±10 % tolerance margin |
| Input Logic Type | TTL-compatible - accepts 2.0 V min HIGH and 0.8 V max LOW at VCC = 5.0 V, enabling direct connection to legacy microcontroller GPIOs |
| Max Clock Frequency | 55 MHz at VCC = 4.5 V, CL = 15 pF - supports high-speed serial loading in real-time lighting or sensor interface applications |
| Propagation Delay (CP to Q) | 17 ns (typ) to 54 ns (max) - ensures predictable timing margins for synchronous control of LED arrays or relay drivers |
| Operating Temperature | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and powertrain-adjacent placement |
| ESD Protection | HBM >2000 V, CDM >1000 V - withstands handling and board-level transients in automotive manufacturing environments |
Pinout & Package
74HCT164D-Q100 is housed in a plastic small outline package (SO14), SOT108-1, with 14 leads and 3.9 mm body width. The package features gull-wing leads suitable for reflow soldering and AOI-compatible footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (DSA) | Serial data input A | Gated data input; active HIGH enables data entry through DSB - used for daisy-chained or multiplexed serial streams |
| 2 (DSB) | Serial data input B | Gated data input; active HIGH enables data entry through DSA - allows selective channel activation without external logic |
| 3–6, 10–13 (Q0–Q7) | Parallel output terminals | CMOS-buffered outputs driving LEDs, relays, or logic loads; each capable of sourcing/sinking ≥4 mA at VCC = 4.5 V |
| 7 (GND) | Ground reference | Primary 0 V return path; decoupling capacitor must be placed within 5 mm for stable switching performance |
| 8 (CP) | Clock input | Edge-triggered input; data shifts on LOW-to-HIGH transition - requires clean, monotonic rise time ≤13 ns (VCC = 4.5 V) |
| 9 (MR) | Master reset | Asynchronous active-LOW input; clears all Q outputs immediately regardless of CP state - critical for fail-safe initialization |
| 14 (VCC) | Positive supply | Power rail connection; requires local 100 nF ceramic decoupling adjacent to pin to suppress switching noise |
Key Features
| Feature | Design Value |
|---|---|
| Dual gated serial inputs | DSA and DSB act as mutual enables - eliminates need for external AND gates in multi-source serial bus architectures |
| AEC-Q100 Grade 1 qualification | Validated for −40 °C to +125 °C operation with full electrical testing across temperature - meets OEM requirements for engine bay ECUs |
| Clamp diode protected inputs | Enables safe interfacing to 12 V signals using series current-limiting resistors - reduces BOM count in mixed-voltage domains |
| Low dynamic power dissipation | CPD = 40 pF - limits switching current draw and self-heating in high-frequency LED scanning applications |
| Wide noise immunity | VIH = 2.0 V (min), VIL = 0.8 V (max) at VCC = 5.0 V - rejects >1.2 V of common-mode noise on serial lines in electrically noisy vehicles |

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 |
|---|---|---|---|
| 74HC164D-Q100 | CMOS input thresholds (VIH = 3.15 V min at VCC = 4.5 V); higher propagation delay (34 ns max vs. 54 ns) | Better suited for 3.3 V MCU interfaces; less tolerant of slow-rising 5 V signals | Select when interfacing to 3.3 V logic families or when lower static current (<8 μA) is prioritized over speed |
| SN74LV164APWRE4 | Lower VCC range (2.0–5.5 V); LV logic family with 1.67 V VIH at 3.3 V; no AEC-Q100 qualification | Not automotive-qualified; requires external reset coordination for fail-safe startup | Use only in non-automotive industrial or consumer systems where cost and 3.3 V compatibility outweigh qualification needs |
Compared with 74HC164D-Q100, the 74HCT164D-Q100 offers tighter timing control for 5 V systems and guaranteed TTL compatibility, while SN74LV164APWRE4 provides broader voltage flexibility at the expense of automotive compliance and deterministic reset behavior.

FAQ
Can 74HCT164D-Q100 operate reliably at 125 °C junction temperature?
Yes. The device is fully characterized and qualified for continuous operation from −40 °C to +125 °C ambient temperature per AEC-Q100 Grade 1. Thermal derating of total power dissipation (500 mW at 25 °C) applies linearly above 100 °C (−10.1 mW/K), ensuring safe operation under sustained high-temperature conditions typical in engine compartments.
What is the minimum pulse width required on the MR pin to guarantee reset?
The minimum MR pulse width is 10 ns at VCC = 4.5 V, as specified in Table 7 (tW). This ensures reliable asynchronous clearing of all eight flip-flops. For robust system design, a 100 ns minimum pulse width is recommended to accommodate PCB trace delays and noise margins in automotive harness environments.
How does the dual-input gating (DSA/DSB) function in practice?
When DSA is HIGH, data at DSB is loaded on the next CP rising edge; when DSB is HIGH, data at DSA is loaded. Both inputs LOW block data entry. This enables hardware-selectable serial channels - for example, DSA can carry command data while DSB carries payload data, with one pin acting as channel select without software intervention.
Is the SO14 package (SOT108-1) compatible with standard reflow profiles?
Yes. The SOT108-1 package is rated for standard lead-free reflow profiles (J-STD-020), including peak temperatures up to 260 °C for 30 seconds. Its gull-wing lead geometry ensures reliable solder joint formation and automated optical inspection (AOI) capability, meeting Tier-1 automotive assembly requirements.
