Product details
Overview
74HC595DB-Q100 from Nexperia is an AEC-Q100 Grade 1 qualified 8-bit serial-in, serial-or-parallel-out shift register with storage latch and 3-state outputs, operating from -40 °C to +125 °C. It features separate shift (SHCP) and storage (STCP) clocks, asynchronous master reset (MR), serial output (Q7S) for daisy-chaining, and active-low output enable (OE). Used in automotive body control modules for LED matrix expansion and multiplexed I/O buffering.
For engineers reviewing the 74HC595DB-Q100 datasheet, 74HC595DB-Q100 pinout, 74HC595DB-Q100 application, or 74HC595DB-Q100 equivalent, key selection criteria include its 100 MHz typical shift-out frequency, CMOS-level input compatibility, 3.3 V/5 V supply operation, and DHVQFN16 package with side-wettable flanks for AOI-compatible solder joint inspection.
Technical Context
This device implements dual-register architecture: an 8-stage shift register accepting serial data on DS at SHCP rising edges, and a parallel-output storage register loaded on STCP rising edges. The storage register drives eight buffered Q0–Q7 outputs, which enter high-impedance state when OE is HIGH.
MR asynchronously clears only the shift register (not storage), enabling independent reset of incoming data flow without disturbing latched outputs. Input clamp diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors - critical for mixed-voltage automotive signal conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | 8-bit serial-in, serial-or-parallel-out shift register with storage latch and 3-state outputs |
| Supply Voltage | 2.0 V to 6.0 V - supports 3.3 V and 5 V automotive domains without level translation |
| Max Clock Frequency | 100 MHz (typical) at VCC = 6 V - enables high-speed LED scanning or sensor data aggregation |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and powertrain applications |
| Output Drive | ±35 mA per Qn output - sufficient to directly drive LEDs or logic inputs without external buffers |
| Propagation Delay | 15 ns (SHCP→Q7S), 16 ns (STCP→Qn) at VCC = 6 V - ensures tight timing control in real-time I/O expansion |
| ESD Rating | HBM >2000 V, CDM >1000 V - robust against assembly and in-vehicle electrostatic events |
Pinout & Package
DHVQFN16 (SOT763-1) package: 2.5 × 3.5 × 0.85 mm body, no leads, 16 terminals, side-wettable flanks for automated optical inspection of solder joints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Q0) | Parallel output 0 | LSB of latched parallel output bus; driven only when OE = LOW |
| 2–7 (Q1–Q6) | Parallel outputs 1–6 | Mid-bits of 8-bit storage register output; synchronized to STCP edge |
| 8 (GND) | Ground reference | Primary return path for all internal logic and output drivers; must be low-impedance |
| 9 (Q7S) | Serial output | MSB of shift register; feeds DS of next cascaded device for multi-byte chaining |
| 10 (MR) | Master reset | Asynchronous active-LOW input clearing shift register only; leaves storage register unchanged |
| 11 (SHCP) | Shift clock | Rising-edge-triggered clock for serial data entry into shift register (DS → Q0) |
| 12 (STCP) | Storage clock | Rising-edge-triggered clock transferring shift register contents to storage register and Q0–Q7 outputs |
| 13 (OE) | Output enable | Active-LOW control of Q0–Q7 3-state drivers; does not affect internal register states |
| 14 (DS) | Serial data input | Single-bit serial input feeding stage 0 of shift register on each SHCP rising edge |
| 15 (Q7) | Parallel output 7 | MSB of latched parallel output bus; matches Q7S after STCP pulse if no further shifting occurs |
| 16 (VCC) | Supply voltage | Positive rail for logic and output drivers; decoupling capacitor required within 10 mm |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit serial-to-parallel shift register applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC595D-Q100 | SO16 package (SOT109-1); no side-wettable flanks; 3.9 mm body width | Suitable for legacy PCB layouts and manual rework; lacks AOI support for high-volume SMT lines | Select when board space allows larger footprint and optical inspection is not required. |
| 74HCT595BQ-Q100 | TTL-compatible inputs (VIH = 2.0 V min); identical DHVQFN16 package and pinout | Better noise margin in noisy 5 V automotive environments with marginal logic thresholds | Choose for direct interface with older 5 V microcontrollers lacking CMOS-level output swing. |
Compared with 74HC595D-Q100, the DB variant offers superior manufacturability via side-wettable flanks; versus 74HCT595BQ-Q100, it provides tighter input threshold control for modern low-voltage MCUs but requires clean 3.3 V signaling.

FAQ
Can 74HC595DB-Q100 operate at 3.3 V supply?
Yes. The 74HC595DB-Q100 is fully specified from 2.0 V to 6.0 V, with guaranteed operation at 3.3 V including VIH/VIL thresholds, propagation delays, and output drive strength. At VCC = 3.3 V, VOH ≥ 2.97 V and VOL ≤ 0.33 V under 4 mA load, meeting standard 3.3 V LVTTL requirements.
What is the function of Q7S versus Q7?
Q7S is the serial output of the shift register - it reflects the MSB (stage 7) *before* transfer to the storage register. Q7 is the parallel output of the storage register - it reflects the latched value transferred on the last STCP edge. Q7S enables daisy-chaining; Q7 provides stable, glitch-free parallel output.
Does MR reset both shift and storage registers?
No. MR only resets the 8-stage shift register to all zeros; the storage register and its Q0–Q7 outputs remain unaffected. This allows safe clearing of incoming serial data without disrupting currently displayed or actuated outputs - essential for fault-tolerant automotive subsystems.
Is the DHVQFN16 package lead-free and RoHS compliant?
Yes. The 74HC595DB-Q100 in SOT763-1 (DHVQFN16) package is manufactured using lead-free solderable terminations and complies with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with full material declarations available through Nexperia's compliance portal.
