Product details
Overview
74HC4094PW,112 from Nexperia is an 8-bit serial-in/parallel-out shift-and-store bus register with separate shift and storage clocks, 3-state outputs, and cascading capability via QS1/QS2 serial outputs. It operates from 2.0 V to 6.0 V, supports -40 °C to +125 °C ambient range, and delivers 39 ns typical propagation delay (CP to QPn at VCC = 4.5 V). It is used in LED matrix drivers and remote control hold registers where serial-to-parallel expansion is required.
For engineers reviewing the 74HC4094PW,112 datasheet, 74HC4094PW,112 pinout, 74HC4094PW,112 application, or 74HC4094PW,112 equivalent, this device serves as a low-power, CMOS-level shift-register solution for industrial I/O expansion, display multiplexing, and embedded control logic requiring precise strobe-controlled output latching and high-impedance state management.
Technical Context
The 74HC4094PW,112 implements a dual-register architecture: an 8-stage shift register clocked on CP's rising edge and an independent 8-bit storage register loaded synchronously on 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 varying clock edge rates.
Its 3-state parallel outputs (QP0–QP7) are enabled by OE, which has no effect on internal register states. Input clamp diodes allow safe interfacing with voltages exceeding VCC when used with current-limiting resistors, supporting mixed-voltage system integration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | 74HC (High-speed CMOS), TTL-compatible input thresholds not supported - requires CMOS-level drive. |
| Supply Voltage Range | 2.0 V to 6.0 V - enables direct interface with 3.3 V and 5 V microcontrollers without level shifting. |
| Propagation Delay (CP → QPn) | 39 ns typ @ VCC = 4.5 V - determines maximum data throughput in cascaded chains (e.g., 25.6 MHz theoretical max). |
| Operating Temperature | -40 °C to +125 °C - qualified for automotive under-hood and industrial motor-control environments. |
| Output Drive Strength | ±4.0 mA @ VCC = 4.5 V - sufficient to directly drive LEDs or small-signal logic inputs without external buffers. |
| Power Dissipation | 83 pF CPD - enables accurate dynamic power estimation (PD = CPD × VCC² × fi × N) for thermal design. |
Pinout & Package
TSSOP16 package (SOT403-1), 4.4 mm body width, 0.65 mm lead pitch, surface-mount, moisture-sensitive level 1 (MSL1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - STR | Strobe input | Transfers data from shift register to storage register on HIGH; asynchronous latch enable with no clock dependency. |
| 2 - D | Serial data input | Accepts new bit on each LOW-to-HIGH CP transition; synchronous to CP, not STR. |
| 3 - CP | Shift clock input | Rising-edge triggered; controls both shift register advancement and QS1 output timing. |
| 4–7, 11–14 - QP0–QP7 | Parallel outputs | 8-bit latched outputs enabled only when OE = HIGH; high-impedance when OE = LOW. |
| 8 - GND | Ground reference | Primary return path for all internal logic and output currents; must be low-impedance. |
| 9, 10 - QS1, QS2 | Cascading serial outputs | QS1 mirrors shift register stage 6 on CP↑; QS2 mirrors stage 7 on CP↓ - enables daisy-chaining without external logic. |
| 15 - OE | Output enable | Active-HIGH; disables all QPn outputs to high-Z without affecting register contents or shift operation. |
| 16 - VCC | Supply voltage | Power rail for logic core and output drivers; decoupling capacitor (100 nF) recommended adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-clock architecture | Independent CP (shift) and STR (latch) inputs eliminate timing conflicts between data loading and output update. |
| Cascading support | QS1/QS2 outputs provide phase-aligned and delayed serial data paths - simplifies multi-device chaining without glue logic. |
| CMOS input compatibility | VIH ≥ 3.15 V @ VCC = 4.5 V ensures reliable recognition of 3.3 V logic HIGHs from modern MCUs. |
| Input clamp diodes | Enable safe connection to voltages > VCC (e.g., 12 V sensor lines) using series current-limiting resistors. |
| Wide temperature range | Specified from -40 °C to +125 °C - supports deployment in engine control units and industrial PLC I/O modules. |
Applications
| LED Matrix Driver | Industrial I/O Expander |
|---|---|
Use Scenario: Driving 8×8 monochrome LED displays using SPI-controlled serial data streams. IC Role / Device Role / Timing Role: Serial-to-parallel converter that latches column data on STR while CP shifts row address bits. Use Value: Reduces MCU GPIO count from 16 to 3 (CP, D, STR); eliminates need for external latch ICs or FPGA resources. |
Use Scenario: Adding 8-bit digital output capability to a PLC base unit with limited native I/O. IC Role / Device Role / Timing Role: Output staging register synchronized to controller's scan cycle via STR pulse. Use Value: Enables glitch-free output updates during runtime; OE allows hot-swap-safe isolation of downstream loads. |
| Remote Control Decoder Hold | Automotive Body Controller |
Use Scenario: Holding decoded IR command bits until firmware processes the full frame. IC Role / Device Role / Timing Role: Storage register retains last received byte while shift register accepts next command. Use Value: Prevents data loss during interrupt latency; STR edge-triggered capture ensures deterministic timing. |
Use Scenario: Controlling interior lighting zones and mirror actuators in a centralized body ECU. IC Role / Device Role / Timing Role: Parallel output driver with 3-state capability for shared bus arbitration and fail-safe shutdown. Use Value: OE-driven high-Z mode isolates faulty outputs during diagnostics; -40 °C to +125 °C rating matches vehicle thermal envelope. |
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 |
|---|---|---|---|
| 74HCT4094PW,112 | Uses TTL-compatible input thresholds (VIH = 2.0 V min @ VCC = 4.5 V); identical pinout and function. | Better suited for legacy 5 V systems with 74LS/74ALS drivers; higher input current draw on CP/STR. | Select when interfacing with older TTL logic families or when VIH < 3.15 V is required. |
| SN74HC595PWR | Single clock (SHCP) for shift + STCP for store; no QS2 output; open-drain OE not available. | Lacks dual-phase serial output for slow-edge cascading; lower propagation delay (25 ns) but no STR-asynchronous latch. | Prefer for cost-sensitive, single-clock designs where QS2 timing flexibility is unnecessary. |
Compared with 74HCT4094PW,112, the 74HC4094PW,112 offers superior noise immunity and lower static current but requires CMOS-level inputs; versus SN74HC595PWR, it provides more robust cascading control and true asynchronous strobe latching at the cost of slightly higher propagation delay.

FAQ
Can 74HC4094PW,112 operate at 3.3 V supply?
Yes. The 74HC4094PW,112 is fully specified from 2.0 V to 6.0 V, including 3.3 V operation. At VCC = 3.3 V, VIH is guaranteed ≥ 2.31 V and VOL ≤ 0.33 V at 4 mA load, ensuring compatibility with standard 3.3 V microcontrollers and logic families.
What is the purpose of QS1 and QS2 outputs?
QS1 outputs the data from shift register stage 6 on the same CP rising edge that advances the register; QS2 outputs stage 7 on the subsequent CP falling edge. This dual-phase output enables reliable cascading under both fast (QS1-synchronized) and slow (QS2-synchronized) clock edge conditions without added timing margin.
Does OE affect internal register states?
No. The OE input controls only the output buffer enable state. When OE is LOW, QP0–QP7 enter high-impedance mode, but the contents of both the shift register and storage register remain unchanged and continue to respond to CP and STR inputs normally.
Is the TSSOP16 package RoHS-compliant and lead-free?
Yes. The 74HC4094PW,112 in SOT403-1 (TSSOP16) packaging meets RoHS Directive 2011/65/EU and is lead-free, halogen-free, and compliant with Nexperia's environmental policy. Moisture sensitivity level is MSL1 - no bake requirement prior to reflow.
