Product details
Overview
74LV4094PW,118 from Nexperia is an 8-bit serial-in/parallel-out shift-and-store bus register with independent shift and storage clocks, 3-state outputs, dual serial outputs (QS1/QS2) for daisy-chaining, and operation across 1.0 V–3.6 V supply. It performs serial-to-parallel data conversion in LED matrix drivers and remote I/O expanders, with propagation delays as low as 17 ns at 3.3 V and 15 pF load.
For engineers reviewing the 74LV4094PW,118 datasheet, 74LV4094PW,118 pinout, 74LV4094PW,118 application, or 74LV4094PW,118 equivalent, key selection criteria include its dual-edge-cascadable serial outputs, -40 °C to +125 °C temperature rating, TSSOP16 package footprint, and guaranteed 3.3 V timing performance with 6 mA drive capability.
Technical Context
The device implements two synchronized but independently clocked 8-bit registers: a shift register accepting serial data on CP rising edges, and a storage register loaded on STR high. QS1 delivers shifted data on the same CP rising edge; QS2 delivers it on the subsequent CP falling edge-enabling robust cascading under both fast and slow clock edge conditions.
Its 3-state outputs are controlled solely by OE (active-high), with no effect on internal register states. Input clamp diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors, and latch-up immunity exceeds 100 mA per JESD78 Class II Level B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.0 V to 3.6 V - Enables direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters. |
| Propagation Delay (CP to QPn) | 17 ns typical at VCC = 3.3 V, CL = 15 pF - Supports >50 MHz system clock rates in synchronous data pipelines. |
| Output Drive Strength | ±6 mA at VCC = 3.0 V - Sufficient to directly drive LEDs or standard CMOS/TTL inputs without external buffers. |
| Operating Temperature | -40 °C to +125 °C - Qualified for industrial and extended-temperature embedded control applications. |
| Input Voltage Thresholds | VIH = 2.0 V min (VCC ≥ 2.7 V); VIL = 0.8 V max - Ensures reliable TTL-level compatibility at 3.3 V supply. |
| Power Dissipation Capacitance | 83 pF - Used to calculate dynamic power: PD = CPD × VCC² × fi × N + Σ(CL × VCC² × fo). |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - Reduces need for external ESD protection in board-level designs. |
Pinout & Package
TSSOP16 package (SOT403-1): 4.4 mm body width, 0.65 mm lead pitch, 16-pin surface-mount outline optimized for high-density PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (STR) | Strobe input | Transfers data from shift register to storage register on HIGH; enables synchronized parallel output updates. |
| 2 (D) | Serial data input | Accepts LSB-first serial data stream synchronized to CP rising edge. |
| 3 (CP) | Shift clock input | Drives shift register on LOW-to-HIGH transition; controls QS1/QS2 timing relationship. |
| 4–7, 11–14 (QP0–QP7) | Parallel outputs | 8-bit 3-state buffered outputs; driven only when OE = HIGH and STR has latched data. |
| 8 (GND) | Ground reference | Return path for all internal logic and output currents; must be low-impedance for noise control. |
| 9 (QS1) | Fast serial output | Delivers shifted data on same CP rising edge-optimized for high-speed cascading. |
| 10 (QS2) | Slow serial output | Delivers same data on next CP falling edge-tolerates slower edge rates in long chains. |
| 15 (OE) | Output enable | Active-HIGH control of QP0–QP7 3-state drivers; does not affect internal register states. |
| 16 (VCC) | Supply voltage | Single 1.0–3.6 V rail powers entire logic and output stages; supports mixed-voltage system integration. |
Key Features
| Feature | Design Value |
|---|---|
| Dual serial outputs with edge-complementary timing | QS1 (CP↑) and QS2 (CP↓) eliminate setup/hold violations in multi-stage shift chains. |
| Wide supply range with TTL-compatible inputs | Operates from 1.0 V to 3.6 V while accepting 2.0 V VIH at 3.3 V-reduces BOM count in mixed-voltage systems. |
| Robust ESD and latch-up immunity | HBM > 2000 V and latch-up > 100 mA meet industrial reliability requirements without added protection circuitry. |
| Low ground bounce and undershoot | Typical ground bounce < 0.8 V and VOH undershoot > 2 V at 3.3 V reduce signal integrity risks in dense routing. |
| Extended temperature qualification | Specified from -40 °C to +125 °C-validates use in automotive under-hood, industrial motor drives, and outdoor equipment. |

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 |
|---|---|---|---|
| SN74LV8154N | 16-bit register, wider bus, higher ICC (max 100 μA), SOIC-24 package | Requires more PCB area and supports double the data width-suited for high-channel-count I/O expansion. | Select when 16-bit parallel output is required and TSSOP16 footprint is not mandatory. |
| 74HC595PW | Higher VCC range (2–6 V), slower tpd (≥25 ns @ 4.5 V), no QS2 output, same TSSOP16 package | Lacks dual-edge serial output-limits cascading robustness in noisy or high-skew environments. | Choose only if cost sensitivity outweighs timing margin needs and 3.3 V operation is not primary. |
Compared with SN74LV8154N and 74HC595PW, the 74LV4094PW,118 uniquely balances ultra-low-voltage operation (1.0 V), sub-20 ns propagation delay at 3.3 V, and dual-cascadable serial outputs-making it optimal for space-constrained, low-power, high-reliability industrial and automotive display/control nodes.

FAQ
What is the maximum clock frequency supported by the 74LV4094PW,118?
The 74LV4094PW,118 supports up to 95 MHz maximum clock frequency at VCC = 3.3 V and CL = 15 pF, as specified in Table 7 of the datasheet. At lower supply voltages (e.g., 2.0 V), fmax drops to 52 MHz. This rating assumes proper layout, decoupling, and load conditions-actual system-level frequency may be limited by board parasitics and drive strength.
Can QS1 and QS2 be used simultaneously in a single daisy-chain configuration?
Yes-QS1 and QS2 are functionally identical outputs carrying the same shifted data, timed to different clock edges. In practice, QS1 connects to CP of the next stage for high-speed chaining, while QS2 feeds the same next-stage CP via a delay element or is used as a diagnostic tap. Both outputs are electrically buffered and rated for 6 mA drive.
Does the OE pin affect internal register states during operation?
No-the OE pin controls only the 3-state output drivers for QP0–QP7. Internal shift and storage registers continue operating normally regardless of OE state. Data can be shifted and latched while outputs remain in high-impedance mode, enabling glitch-free bus sharing and hot-swap-safe configurations.
Is the 74LV4094PW,118 qualified for automotive applications?
The 74LV4094PW,118 is specified for -40 °C to +125 °C operation and meets JESD8-5/8C standards, but Nexperia does not classify it as AEC-Q100 automotive-qualified. It is suitable for non-safety-critical automotive body electronics (e.g., interior lighting, mirror controls) where full qualification is not mandated-but not for ADAS, powertrain, or safety systems.
