Product details
Overview
74LV4094DB,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 to 3.6 V supply. It performs serial-to-parallel data conversion in LED matrix drivers, remote control hold registers, and I/O expansion interfaces.
For engineers reviewing the 74LV4094DB,118 datasheet, 74LV4094DB,118 pinout, 74LV4094DB,118 application, or 74LV4094DB,118 equivalent, key selection factors include its dual-edge cascading capability (QS1 on CP↑, QS2 on CP↓), -40 °C to +125 °C temperature rating, SO16 package (SOT109-1), 3.3 V propagation delay of 17 ns (CP→QPn), and 3-state output enable timing (17 ns enable / 14 ns disable).
Technical Context
The device implements two synchronized but functionally separate 8-stage registers: a shift register clocked on CP rising edges and a storage register loaded on STR high. Data propagates through the shift register at up to 95 MHz (VCC = 3.3 V, CL = 15 pF) and transfers atomically to the storage register upon STR assertion.
Output control is fully decoupled from register operation: OE toggles 3-state output drivers without affecting internal state, while input clamp diodes permit safe interfacing to voltages exceeding VCC when used with current-limiting resistors.
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 → QPn) | 17 ns at VCC = 3.3 V, CL = 15 pF - Determines maximum achievable shift rate in time-critical serial loading sequences. |
| Enable/Disable Time (OE → QPn) | 17 ns enable / 14 ns disable at VCC = 3.3 V - Supports rapid output gating for dynamic bus sharing or power sequencing. |
| Operating Temperature | -40 °C to +125 °C - Qualified for under-hood automotive modules, industrial PLCs, and high-reliability embedded controllers. |
| Output Drive Strength | ±6 mA at VOH/VOL (VCC = 3.0 V) - Sufficient to directly drive LEDs or standard CMOS/TTL inputs without external buffers. |
| Power Dissipation Capacitance | 83 pF - Used to calculate dynamic power consumption (PD = CPD × VCC² × fi × N) in high-frequency applications. |
| ESD Robustness | HBM > 2000 V, CDM > 1000 V - Reduces susceptibility to handling damage during PCB assembly and field service. |
Pinout & Package
74LV4094DB,118 is supplied in a plastic small outline package (SO16) per SOT109-1, with 16 leads, 3.9 mm body width, and standard 1.27 mm lead pitch. Pin 1 is marked by a notch or dot; pin numbering follows counter-clockwise convention starting from top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (STR) | Strobe input | Transfers contents of shift register into storage register on HIGH; asynchronous to CP and OE. |
| 2 (D) | Serial data input | Accepts new bit on each LOW-to-HIGH transition of CP; TTL-compatible at VCC ≥ 2.7 V. |
| 3 (CP) | Shift clock input | Rising-edge triggered; controls data movement through shift register and determines QS1 output timing. |
| 4–7, 11–14 (QP0–QP7) | Parallel outputs | 8-bit buffered storage register outputs; driven only when OE = HIGH; high-impedance otherwise. |
| 8 (GND) | Ground reference | Primary return path for all internal logic and output currents; must be low-impedance for noise immunity. |
| 9 (QS1) | Fast serial output | Repeats QP6 on CP↑ - enables tight-tolerance cascading where clock edges are fast and predictable. |
| 10 (QS2) | Slow serial output | Repeats QP7 on CP↓ - supports robust daisy-chaining under slow or skewed clock edge conditions. |
| 15 (OE) | Output enable | Active-HIGH; places QP0–QP7 in high-Z state without altering register contents or affecting QS1/QS2. |
| 16 (VCC) | Supply voltage | Single rail powering both logic core and output drivers; accepts 1.0–3.6 V with full functionality. |
Key Features
| Feature | Design Value |
|---|---|
| Dual serial outputs with edge-selectable timing | QS1 (CP↑) and QS2 (CP↓) allow flexible cascading architecture-no external delay elements needed. |
| Wide VCC range with guaranteed operation down to 1.0 V | Supports battery-powered systems and mixed-voltage designs without regulator overhead or translation circuitry. |
| Input clamp diodes with current-limiting resistor support | Enables safe connection to 5 V signals or other overvoltage sources using simple series resistors. |
| Low ground bounce (< 0.8 V typical) | Maintains signal integrity in dense PCB layouts with shared ground planes and multiple switching outputs. |
| Latch-up immunity > 100 mA (JESD78 Class II Level B) | Ensures robustness against transient overcurrent events common in hot-plug or ESD-prone environments. |
Applications
| LED Matrix Driver | I/O Expansion Interface |
|---|---|
Use Scenario: Driving 8×8 monochrome LED displays in consumer electronics and signage. IC Role / Device Role / Timing Role: Serial-to-parallel converter that latches column data for static display refresh; QS1/QS2 enable multi-display chaining. Use Value: Eliminates need for microcontroller GPIO expansion; 3-state outputs prevent ghosting during multiplexed row scanning. | Use Scenario: Adding parallel output ports to microcontrollers with limited GPIO count (e.g., STM32L0, nRF52). IC Role / Device Role / Timing Role: Shift-register-based port expander controlled via SPI-like serial interface; STR synchronizes output updates. Use Value: Reduces firmware overhead vs. software bit-banging; deterministic update timing avoids race conditions in real-time control loops. |
| Remote Control Holding Register | Industrial Sensor Data Aggregation |
Use Scenario: Capturing and holding IR remote command codes before MCU wake-up in ultra-low-power modes. IC Role / Device Role / Timing Role: Low-voltage (1.8 V) shift register storing incoming pulse-width modulated bits; OE holds outputs stable during MCU sleep. Use Value: Enables sub-μA system standby current; STR-triggered latch ensures no data loss across wake-up latency. | Use Scenario: Consolidating status bits from distributed sensors (e.g., door switches, fault indicators) in factory automation panels. IC Role / Device Role / Timing Role: Parallel-output bus register collecting discrete sensor states; cascaded via QS1/QS2 to aggregate >8 inputs per controller. Use Value: Simplifies wiring and reduces polling overhead; 125 °C rating supports deployment near motors or power supplies. |
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 shift register with integrated 32-bit counter; wider bus, higher pin count (24-pin PDIP), no QS2 output. | Designed for metering and energy monitoring where counting and shifting coexist; lacks dual-edge cascade support. | Select when extended bit width and on-chip counting are required; avoid if board space or cascade flexibility is constrained. |
| 74HC595PW,118 | Same 8-bit function but HC family: VCC = 2–6 V, slower max frequency (25 MHz @ 4.5 V), no QS2 output, TSSOP16 only. | Targeted at legacy 5 V systems; lacks low-voltage operation and second serial output for robust daisy-chaining. | Choose for cost-sensitive 5 V designs where 3.3 V compatibility and advanced cascade timing are unnecessary. |
Compared with SN74LV8154N and 74HC595PW,118, the 74LV4094DB,118 uniquely balances ultra-low-voltage operation (1.0 V), dual-edge serial output flexibility, and industrial temperature range - making it optimal for compact, battery-aware, and cascade-dense applications.

FAQ
What is the minimum supply voltage at which 74LV4094DB,118 guarantees full functionality?
The device is specified to operate down to 1.0 V with full functionality, including correct logic levels, timing, and output drive strength. Static characteristics are guaranteed from 1.2 V, but functional operation (data shifting, storage, and 3-state control) is validated at 1.0 V per Nexperia's characterization - critical for coin-cell or energy-harvesting applications.
Can QS1 and QS2 be used simultaneously to feed different downstream devices?
Yes - QS1 and QS2 provide identical data (QP6 and QP7 respectively) on complementary clock edges and may drive separate cascaded registers. Their outputs are electrically isolated and can source/sink ±6 mA independently, enabling split-path daisy chains without buffering or timing skew concerns.
How does the STR input interact with ongoing shift operations?
STR is asynchronous and independent of CP: asserting STR HIGH captures the current state of the shift register into the storage register regardless of CP activity. Subsequent shifts continue in the shift register without affecting the latched parallel outputs - enabling precise output update timing decoupled from serial load rate.
Is 74LV4094DB,118 qualified for automotive applications?
No - although rated for -40 °C to +125 °C, this part is not AEC-Q200 qualified and lacks automotive-specific testing (e.g., HTOL, ESD stress beyond JESD22). Nexperia explicitly states non-automotive qualification in its legal disclaimers; use only in industrial, consumer, or computing applications unless separately validated.
