Product details
Overview
74LV4094D,112 from Nexperia is an 8-bit serial-in/parallel-out shift-and-store bus register with independent shift and storage clocks, 3-state outputs, and dual serial outputs (QS1/QS2) for daisy-chain cascading. It operates from 1.0 V to 3.6 V, supports TTL-level inputs at VCC ≥ 2.7 V, and delivers propagation delays as low as 17 ns (VCC = 3.3 V, CL = 15 pF). It is used in LED matrix drivers and remote control holding registers where space-constrained serial-to-parallel conversion is required.
For engineers reviewing the 74LV4094D,112 datasheet, 74LV4094D,112 pinout, 74LV4094D,112 application, or 74LV4094D,112 equivalent, this device offers verified timing behavior across -40 °C to +125 °C, confirmed 3-state output control via OE, dual-edge-cascadable serial outputs, and SO16 package compatibility with standard PCB footprints.
Technical Context
The 74LV4094D implements a two-stage pipeline: an 8-bit shift register clocked on CP rising edges, followed by an 8-bit storage latch triggered by STR high. Data advances through the shift register on each CP ↑, while QS1 reflects stage Q6S on the same edge and QS2 reflects Q7S on the subsequent CP ↓ - enabling robust inter-device synchronization under varying clock edge rates.
Its 3-state parallel outputs (QP0–QP7) are enabled only when OE is HIGH; OE LOW forces all outputs into high-impedance without affecting internal register states. Input clamp diodes allow 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 integration into ultra-low-voltage microcontroller I/O domains and battery-powered systems. |
| Propagation delay (CP to QPn) | 17 ns typical at VCC = 3.3 V, CL = 15 pF - ensures reliable timing margin in 50 MHz+ serial data streams. |
| Maximum clock frequency | 95 MHz at VCC = 3.3 V, CL = 15 pF - supports high-throughput serial loading in display and lighting controllers. |
| Output drive strength | ±6 mA at VOH/VOL - sufficient to directly drive LEDs or interface with standard CMOS/TTL loads without external buffers. |
| Operating temperature | -40 °C to +125 °C - qualified for industrial and under-hood automotive auxiliary applications. |
| ESD protection | HBM > 2000 V, CDM > 1000 V - reduces risk of handling damage during manual assembly and board rework. |
Pinout & Package
74LV4094D,112 is housed in a 16-pin SO16 (SOT109-1) plastic small outline package with 3.9 mm body width, 1.27 mm lead pitch, and gull-wing leads compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (STR) | Strobe input | Transfers data from shift register to storage register on HIGH assertion; asynchronous to CP. |
| 2 (D) | Serial data input | Accepts new bit on each CP rising edge; TTL-compatible when VCC ≥ 2.7 V. |
| 3 (CP) | Shift clock input | Rising-edge-triggered; controls data advancement and QS1 output timing. |
| 4–7, 11–14 (QP0–QP7) | Parallel outputs | 3-state buffered outputs; driven only when OE = HIGH; QP0–QP7 map directly to stored bits. |
| 8 (GND) | Ground reference | Primary return path for logic and output currents; must be low-impedance for noise immunity. |
| 9 (QS1) | Fast serial output | Reflects Q6S on CP ↑ - optimized for cascading with fast clock edges. |
| 10 (QS2) | Slow serial output | Reflects Q7S on CP ↓ - enables reliable daisy-chaining with slower or skewed clocks. |
| 15 (OE) | Output enable | Active-HIGH; disables all QPn outputs to high-Z without altering register contents. |
| 16 (VCC) | Supply voltage | Power rail for logic and output stages; decoupling capacitor required near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Dual serial outputs with edge-aligned timing | QS1 (CP ↑) and QS2 (CP ↓) eliminate setup/hold violations in multi-device chains. |
| Wide supply voltage operation | 1.0 V to 3.6 V allows use with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic families without level shifters. |
| Input clamp diodes | Enable safe connection to signals up to VCC + 0.5 V using series current-limiting resistors. |
| Low ground bounce | < 0.8 V typical at VCC = 3.3 V - maintains signal integrity during simultaneous output switching. |
| High-temperature qualification | Specified from -40 °C to +125 °C - suitable for industrial motor drives and power supply monitoring circuits. |
Applications
| LED Matrix Driver | Remote Control Decoder Buffer |
|---|---|
|
Use Scenario: Driving 8×8 monochrome LED displays using microcontroller GPIO-constrained serial interfaces. IC Role / Device Role / Timing Role: Serial-to-parallel converter that latches column data synchronously with row scanning, minimizing ghosting via precise STR timing. Use Value: Eliminates need for external latches; QS1/QS2 support seamless expansion to larger matrices without added timing complexity. |
Use Scenario: Holding decoded IR command bits in consumer electronics remotes before MCU polling. IC Role / Device Role / Timing Role: Holding register that captures and retains command payload until host reads QP0–QP7, isolated from ongoing IR reception. Use Value: Enables low-power MCU sleep between commands; OE control allows shared bus access without data corruption. |
| Industrial I/O Expander | Programmable Logic Interface |
|
Use Scenario: Adding 8-bit parallel output capability to PLC modules with limited native I/O pins. IC Role / Device Role / Timing Role: Bus register providing galvanically isolated (via optocoupler-driven D/CP/STR) output staging for relay banks. Use Value: Supports deterministic update cycles via STR strobe; 3-state outputs prevent bus contention during hot-swap or firmware updates. |
Use Scenario: Configuring signal routing paths in FPGA-based test equipment using static configuration bits. IC Role / Device Role / Timing Role: Non-volatile hold register (with external EEPROM reload) storing FPGA pin-assignment maps during power-up initialization. Use Value: Reduces FPGA configuration time; QS2 output enables verification of loaded bitstream via loopback before system enable. |
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, single-clock architecture; no separate STR input; QS1/QS2 not implemented. | Lacks independent strobe control and dual serial outputs - unsuitable for cascaded timing-critical designs. | Select only if 16-bit width and simplified clocking outweigh loss of strobe flexibility and cascade robustness. |
| 74HC595PW | Higher VCC range (2 V–6 V); no QS2 output; propagation delay ~25 ns at 4.5 V (slower than LV variant). | Not rated for 125 °C operation; lacks slow-edge cascade capability - limits use in extended-temperature industrial settings. | Prefer for legacy 5 V systems where temperature range ≤ 85 °C and cascade timing margins are generous. |
Compared with SN74LV8154N and 74HC595PW, the 74LV4094D,112 uniquely combines wide-voltage operation, dual-edge serial outputs, and full -40 °C to +125 °C qualification - making it the only option supporting high-reliability, multi-stage serial expansion in thermally demanding environments.

FAQ
What is the minimum supply voltage for guaranteed operation of the 74LV4094D,112?
The 74LV4094D,112 is fully specified and guaranteed functional at VCC = 1.0 V, with input levels referenced to GND or VCC. Static characteristics are validated down to this level, though propagation delays increase versus 3.3 V operation - see Table 5 and Table 7 for voltage-dependent timing values.
Can QS1 and QS2 be used simultaneously to drive different downstream devices?
Yes - QS1 and QS2 provide identical data content with precisely timed offsets: QS1 updates on CP rising edge, QS2 updates on the following CP falling edge. This allows one device to feed QS1 to a fast-responding load (e.g., FPGA), while QS2 feeds a slower peripheral (e.g., microcontroller input), eliminating inter-device skew.
Does asserting OE LOW affect the internal shift or storage register states?
No - OE is purely an output gate control. When OE is LOW, QP0–QP7 enter high-impedance but retain their last latched values. The shift register continues advancing on CP edges, and STR remains fully functional to update the storage register - enabling seamless output disable/re-enable without data loss.
Is the 74LV4094D,112 pin-compatible with other packages of the same part number?
Yes - the 74LV4094D (SO16/SOT109-1), 74LV4094PW (TSSOP16/SOT403-1), and legacy 74LV4094DB (SSOP16) share identical pin functions and ordering codes. However, mechanical dimensions, thermal resistance, and PCB footprint differ; SO16 and TSSOP16 are not physically interchangeable without layout revision.
