Product details
Overview
74HCT4094DB-Q100 from Nexperia is an automotive-grade 8-bit serial-in/parallel-out shift-and-store bus register with separate shift and storage clocks, 3-state outputs, dual serial outputs (QS1/QS2) for daisy-chaining, and TTL-compatible input levels. It operates from -40 °C to +125 °C, supports 4.5–5.5 V supply, and is qualified to AEC-Q100 Grade 1 for use in body control modules and dashboard display drivers.
For engineers reviewing the 74HCT4094DB-Q100 datasheet, 74HCT4094DB-Q100 pinout, 74HCT4094DB-Q100 application, or 74HCT4094DB-Q100 equivalent, key selection criteria include propagation delay (≤59 ns at VCC = 4.5 V), strobe-to-output timing (≤59 ns), output enable response (≤53 ns), and SO16 package compatibility with legacy PCB footprints.
Technical Context
This device implements a two-stage pipeline: an 8-bit shift register accepting serial data on CP rising edges, and an independent 8-bit storage latch triggered by STR high. Data appears at QS1 on the same CP rising edge and at QS2 on the subsequent CP falling edge-enabling robust cascading under both fast- and slow-edge clock conditions.
The 3-state parallel outputs (QP0–QP7) are controlled solely by OE, with no effect on internal register states. Input clamp diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors, supporting mixed-voltage system integration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | 74HCT - TTL-compatible inputs, CMOS outputs; enables direct interface with legacy microcontrollers and FPGAs without level-shifting. |
| Supply Voltage Range | 4.5 V to 5.5 V - Matches standard automotive 5 V rail; excludes operation below 4.5 V to ensure guaranteed TTL input thresholds. |
| Propagation Delay (CP→QPn) | 25–65 ns at VCC = 4.5 V - Determines maximum achievable shift rate in real-time control loops (e.g., LED matrix refresh). |
| Strobe-to-Output Delay (STR→QPn) | 22–59 ns at VCC = 4.5 V - Defines minimum time between latching serial data and stable parallel output availability. |
| Output Enable Timing | ten ≤ 53 ns, tdis ≤ 53 ns at VCC = 4.5 V - Enables precise bus arbitration in shared-data-path systems like multiplexed sensor arrays. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - Meets automotive assembly-line ESD requirements without external protection components. |
| Operating Temperature | -40 °C to +125 °C - Qualified per AEC-Q100 Grade 1; supports under-hood and instrument cluster deployment. |
Pinout & Package
74HCT4094DB-Q100 uses the SOT109-1 (SO16) plastic small outline package: 16-pin, 3.9 mm body width, 1.27 mm lead pitch, surface-mount, gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (STR) | Strobe input | Latches shifted data from shift register into storage register on HIGH; decouples serial loading from parallel output update. |
| 2 (D) | Serial data input | Accepts single-bit serial stream synchronized to CP rising edge; compatible with MCU GPIO or UART TX. |
| 3 (CP) | Shift clock input | Drives shift register on LOW-to-HIGH transition; QS1 reflects stage-6 data on this edge, QS2 on next falling edge. |
| 4–7, 11–14 (QP0–QP7) | Parallel outputs | 8-bit 3-state outputs; driven only when OE = HIGH; high-impedance when OE = LOW for bus sharing. |
| 8 (GND) | Ground reference | Primary return path for logic and output currents; must be low-impedance to minimize ground bounce in multi-device chains. |
| 9, 10 (QS1, QS2) | Serial outputs | QS1 provides immediate cascade feed; QS2 provides phase-delayed feed for slower-clock domains or noise margin enhancement. |
| 15 (OE) | Output enable | Active-HIGH control of QP0–QP7; does not affect shift or storage registers-enables glitch-free output gating. |
| 16 (VCC) | Supply voltage | 5 V nominal power rail; bypass capacitor (100 nF) required near pin for transient current stability during output switching. |
Key Features
| Feature | Design Value |
|---|---|
| Dual serial outputs with edge-aligned timing | QS1 updates on CP↑ (for fast cascading); QS2 updates on CP↓ (for slow-edge or noise-immune chaining). |
| Independent shift and store clocks | Enables continuous serial loading while holding stable parallel outputs-critical for jitter-sensitive display drivers. |
| AEC-Q100 Grade 1 qualification | Validated for automotive use across -40 °C to +125 °C ambient; includes lifetime reliability testing per JEDEC JESD47. |
| TTL-compatible input thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 5 V-ensures interoperability with 5 V microcontrollers and legacy logic without pull-ups. |
| Input clamp diodes | Allow safe connection to signals up to VCC + 0.5 V using series resistors-simplifies interface to higher-voltage sensors or communication lines. |
Applications
| Automotive Body Control Unit | LED Matrix Display Driver |
|---|---|

Use Value: Reduces MCU GPIO count by 8 per device; QS2's delayed output suppresses metastability in noisy vehicle electrical environments. | Use Scenario: Driving 8×8 or 8×16 segmented LED panels in digital instrument clusters or center consoles. IC Role / Device Role / Timing Role: Shift-register latch providing column scan data with precise strobe-controlled output hold timing. Use Value: STR-to-QPn delay ≤59 ns ensures pixel row/column alignment within display refresh deadlines; 3-state outputs prevent ghosting during multiplexing. |
| Industrial Sensor Interface Hub | Remote Keypad Scan Controller |
Use Scenario: Aggregating status bits from distributed temperature, pressure, and switch sensors in engine bay modules. IC Role / Device Role / Timing Role: Serial-input shift register collecting sensor flags over long traces, then presenting them in parallel to local MCU. Use Value: QS1/QS2 dual outputs support daisy-chained sensor nodes with <100 ns inter-node skew; AEC-Q100 rating ensures field reliability. | Use Scenario: Scanning 8-key mechanical keypad matrices in infotainment front panels or HVAC control units. IC Role / Device Role / Timing Role: Parallel-output latch holding debounced key state for periodic MCU polling via GPIO read. Use Value: OE-controlled 3-state outputs allow shared data bus with other peripherals; low 5.2 mA drive strength prevents contact welding in tactile switches. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit shift-and-store register applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC4094DB-Q100 | CMOS input thresholds (VIH ≥ 3.15 V @ VCC = 4.5 V); higher noise immunity but requires ≥3.15 V logic-high drive. | Suitable where host MCU outputs exceed 3.15 V; less tolerant of marginal 3.3 V logic driving 5 V rails. | Select when interfacing with 3.3 V MCUs with strong output drivers or when higher noise margin is prioritized over drive compatibility. |
| SN74HCT595QPWRQ1 | Single serial output (Q7S); no QS2; different pinout (Q7S at pin 9 vs. QS1/QS2 at pins 9/10); identical AEC-Q100 Grade 1 rating. | Requires external logic for dual-output cascading; lacks QS2's built-in phase delay for slow-edge synchronization. | Choose when board space is constrained and only single-output chaining is needed; verify pin compatibility before footprint reuse. |
Compared with 74HC4094DB-Q100, the subject part offers superior TTL-level drive compatibility in mixed-voltage automotive systems; versus SN74HCT595QPWRQ1, it delivers deterministic dual-edge cascading without added components-reducing BOM count and layout complexity in multi-stage displays.

FAQ
What is the maximum clock frequency supported by 74HCT4094DB-Q100?
The device supports a maximum clock frequency of 24 MHz at VCC = 4.5 V and -40 °C to +85 °C, and 20 MHz across the full -40 °C to +125 °C range. This is determined by the longest propagation path (CP to QPn), which is 65 ns at worst-case conditions. Operation above these frequencies risks setup/hold violations and metastability.
Can QS1 and QS2 be used simultaneously to drive different downstream devices?
Yes-QS1 and QS2 are electrically independent outputs derived from adjacent stages of the shift register. QS1 carries data one clock edge ahead of QS2, enabling simultaneous feeding of two cascaded devices with inherent skew compensation. No additional buffering is required, and both outputs meet the same VOH/VOL specs.
Is the 74HCT4094DB-Q100 pin-compatible with non-automotive 74HCT4094 variants?
Yes-the DB suffix denotes the SO16 (SOT109-1) package, matching industry-standard 74HCT4094 pinouts. However, the -Q100 suffix indicates AEC-Q100 qualification, including enhanced screening, traceability, and extended temperature validation; non-Q100 versions lack this automotive certification and may not meet the same reliability requirements.
How does the strobe (STR) input interact with ongoing shift operations?
STR operates independently of CP: a HIGH pulse on STR transfers the current contents of the shift register into the storage register without halting serial shifting. Subsequent CP edges continue loading new data into the shift register, enabling pipelined operation-critical for real-time display or control applications where latency must be minimized.
