Product details
Overview
74LVC595AD from Nexperia is an 8-bit serial-in/parallel-out shift register with separate shift and storage clocks, 3-state outputs, asynchronous master reset (MR), and Schmitt-trigger inputs. It operates from 1.2 V to 3.6 V, tolerates 5.5 V inputs, and supports mixed-voltage interfacing in LED matrix drivers and I/O expanders.
For engineers reviewing the 74LVC595AD datasheet, 74LVC595AD pinout, 74LVC595AD application, or 74LVC595AD equivalent, key selection criteria include propagation delay (≤7.7 ns at 3.3 V), IOFF-enabled partial power-down, ±24 mA output drive, -40 °C to +125 °C operation, and SO16 package compatibility with legacy PCB footprints.
Technical Context
The device implements two synchronized but independent 8-bit registers: a shift register clocked by SHCP (LOW-to-HIGH edge) and a storage register clocked by STCP (LOW-to-HIGH edge). Data cascades serially via DS → Q7S, enabling daisy-chaining without external logic.
Outputs are enabled by active-LOW OE and placed in high-impedance state when OE = HIGH, independent of register contents. MR asynchronously clears only the shift register, preserving storage register data until next STCP pulse.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 1.2 V to 3.6 V - enables direct interface with 1.8 V, 2.5 V, and 3.3 V logic domains |
| Input overvoltage tolerance | 5.5 V - allows safe connection to 5 V microcontrollers or sensors without level shifters |
| Propagation delay (SHCP→Q7S) | ≤7.7 ns at VCC = 3.3 V - supports >115 MHz shift clock rates in high-speed serial loading |
| Output drive strength | ±24 mA at VCC = 3.0 V - sufficient to directly drive LEDs or small-signal MOSFET gates |
| IOFF current | ≤10 μA at VCC = 0 V - prevents backflow current during hot-swap or partial power-down sequences |
| Operating temperature | -40 °C to +125 °C - qualified for under-hood automotive and industrial control environments |
| ESD rating | HBM >2000 V, CDM >1000 V - meets robustness requirements for automated assembly and field deployment |
Pinout & Package
74LVC595AD uses the SO16 plastic small outline package (SOT109-1), 16-pin, 3.9 mm body width, with standard 1.27 mm pitch and gull-wing leads compatible with reflow and wave soldering.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1–7, 15 | Parallel outputs Q0–Q7 | Active-LOW OE-controlled buffered outputs; Q0–Q7 reflect storage register content |
| 8 | GND | Reference ground for all internal logic and output stages |
| 9 | Q7S | Serial output - shifted-out MSB of shift register, used for cascading |
| 10 | MR | Asynchronous master reset - LOW clears shift register only; no effect on storage register |
| 11 | SHCP | Shift clock - LOW-to-HIGH edge shifts DS into stage 0 and propagates existing bits |
| 12 | STCP | Storage clock - LOW-to-HIGH edge transfers full 8-bit shift register content to storage register |
| 13 | OE | Output enable - LOW enables Q0–Q7; HIGH forces all outputs to high-impedance state |
| 14 | DS | Serial data input - new bit loaded on each SHCP rising edge |
| 16 | VCC | Positive supply - powers both logic core and output buffers; decoupling required per JEDEC guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Separate shift/storage clocks | Enables precise timing control: shift register can be updated while outputs remain stable |
| Schmitt-trigger inputs | Accepts slow-rising signals (≤20 ns/V at 1.65 V) without oscillation or metastability |
| IOFF circuitry | Automatically disables outputs when VCC = 0 V, eliminating backfeed risk in multi-rail systems |
| Overvoltage-tolerant inputs | Supports 5 V signal sources driving 3.3 V logic without external clamping diodes or resistors |
| JEDEC-compliant voltage ranges | Fully specified for JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C (2.7–3.6 V) |
Applications
| LED Matrix Driver | I/O Expansion for Microcontroller |
|---|---|
Use Scenario: Driving 8×8 monochrome LED display using SPI-controlled serial load and parallel output latching. IC Role / Device Role / Timing Role: Shift register converts SPI data stream into parallel column/row enable signals; STCP synchronizes display update to avoid flicker. Use Value: Eliminates need for 8 GPIO pins; supports 100+ Hz refresh with <7.7 ns propagation delay and 24 mA sink capability per output. | Use Scenario: Expanding GPIO count of an ARM Cortex-M0+ MCU with limited I/O for sensor polling and actuator control. IC Role / Device Role / Timing Role: Acts as unidirectional output expander - MCU writes serial data, then pulses STCP to commit to outputs. Use Value: Enables 8 additional robust, 3.3 V-compatible outputs with IOFF protection during MCU sleep modes. |
| Industrial PLC Output Module | Automotive Body Control Unit |
Use Scenario: Controlling solenoid valves and indicator lamps in DIN-rail mounted programmable logic controllers. IC Role / Device Role / Timing Role: Provides isolated, latchable digital outputs with fail-safe MR reset and wide-temp operation. Use Value: -40 °C to +125 °C rating ensures reliability in enclosure-heated environments; 5.5 V tolerant inputs interface directly with 24 V sensor feedback via resistor dividers. | Use Scenario: Managing interior lighting zones and mirror position memory in vehicle body control modules. IC Role / Device Role / Timing Role: Serially loaded configuration data from CAN-connected ECU, then latched to drive LED loads. Use Value: IOFF and overvoltage tolerance prevent bus contention during ignition cycling; 125 °C rating supports placement near HVAC ducts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit serial-in/parallel-out shift register applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LV595A | TI part with identical pinout and function; max VCC = 5.5 V, higher ICC (100 μA vs 40 μA typical) | Preferred where 5 V system integration is required without level shifting | Select if board already uses TI logic family or requires 5 V supply headroom |
| 74HC595 | Higher VCC range (2–6 V); no IOFF, no 1.2 V operation, slower tpd (≈20 ns at 4.5 V) | Suitable for legacy 5 V designs but not for low-voltage or hot-swap scenarios | Choose only for cost-sensitive 5 V-only applications where partial power-down is unnecessary |
Compared with SN74LV595A and 74HC595, the 74LVC595AD offers superior low-voltage operation (down to 1.2 V), lower static current, and built-in IOFF for system-level power sequencing - critical for battery-powered and automotive modules.

FAQ
Can 74LVC595AD operate at 1.8 V supply while interfacing with 5 V microcontrollers?
Yes. The device supports VCC from 1.2 V to 3.6 V and features overvoltage-tolerant inputs rated to 5.5 V. When powered at 1.8 V, it safely accepts 5 V logic signals on DS, SHCP, STCP, MR, and OE without damage or level-shifting circuitry - enabling direct connection to legacy 5 V MCUs.
What happens to the storage register when MR is asserted?
Asserting MR (LOW) clears only the shift register; the storage register and its parallel outputs (Q0–Q7) remain unchanged. This allows safe reset of incoming serial data without disrupting currently displayed or driven outputs - essential for glitch-free display updates and real-time control.
Is the SO16 package (SOT109-1) RoHS compliant and lead-free?
Yes. The 74LVC595AD in SO16 package (SOT109-1) is RoHS compliant and lead-free, meeting EU Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) for unlimited floor life at ≤30 °C/60 % RH.
How does the IOFF feature protect the device during partial power-down?
When VCC = 0 V, the IOFF circuitry disables all outputs, limiting OFF-state leakage to ≤10 μA. This prevents damaging backflow current from live 5 V buses or powered peripherals into the unpowered IC - a critical safeguard in multi-rail systems undergoing controlled power sequencing or hot-swap events.
