Product details
Overview
74VHC595PW-Q100 from Nexperia is an AEC-Q100 Grade 1 qualified 8-bit serial-in/parallel-out shift register with storage latches and 3-state outputs, operating from -40 °C to +125 °C. It features separate shift (SHCP) and storage (STCP) clocks, asynchronous master reset (MR), and TTL-compatible input thresholds (74VHCT variant). Used in automotive LED driver interfaces and remote control data holding circuits.
For engineers reviewing the 74VHC595PW-Q100 datasheet, 74VHC595PW-Q100 pinout, 74VHC595PW-Q100 application, or 74VHC595PW-Q100 equivalent, key selection criteria include propagation delay (≤10.5 ns at VCC = 5 V), 3-state output enable timing (ten ≤13 ns), automotive temperature range compliance, and TSSOP16 package suitability for high-density PCB layouts.
Technical Context
This device implements two synchronized but independent 8-bit registers: an upstream serial shift register clocked by SHCP and a downstream storage register clocked by STCP. Data propagates through the shift register on each SHCP rising edge and transfers to the storage register on each STCP rising edge - enabling precise separation of serial loading and parallel output update.
The 3-state outputs (Q0–Q7) are controlled by OE (active LOW), while MR (active LOW) asynchronously clears only the shift register stages. Input Schmitt triggers ensure noise immunity, and inputs tolerate voltages up to 7.0 V regardless of VCC, supporting mixed-voltage system interfacing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | VHC CMOS - enables 2.0–5.5 V operation with TTL-level compatibility via 74VHCT variant |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive use |
| Propagation Delay | ≤10.5 ns (SHCP→Q7S, VCC = 5 V, CL = 50 pF) - supports >90 MHz serial clock rates |
| Output Drive | ±8 mA (VOH/VOL at VCC = 4.5 V) - directly drives LEDs or standard logic loads without buffering |
| Power Dissipation | CPD = 180 pF - enables accurate dynamic power estimation (PD = CPD × VCC² × fi) |

Pinout & Package
TSSOP16 plastic thin shrink small outline package (SOT403-1), 16-pin, 4.4 mm body width, 0.65 mm pitch - optimized for automated optical inspection (AOI) and space-constrained automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |

| 8 | GND | Reference ground for all internal logic and I/O |
| 9 | Q7S serial output | Cascadable output for daisy-chaining multiple shift registers |
| 10 | MR (Master Reset) | Asynchronous active-LOW clear of shift register only - preserves storage register contents |
| 11 | SHCP (Shift Clock) | Rising-edge-triggered clock for serial data shifting into 8-bit shift register |
| 12 | STCP (Storage Clock) | Rising-edge-triggered clock transferring shift register contents to output latches |
| 13 | OE (Output Enable) | Active-LOW control of Q0–Q7 3-state drivers - enables bus sharing |

| 16 | VCC | Positive supply rail (2.0–5.5 V); powers both logic core and output drivers |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 1 certified - validated for permanent installation in passenger vehicle ECUs |
| Input voltage tolerance | VI up to 7.0 V - allows direct connection to 5 V or 3.3 V microcontrollers without level-shifting |
| Schmitt-trigger inputs | Hysteresis ≥0.5 V (typ.) - rejects noise on long traces or noisy automotive harnesses |
| Separate clock domains | Independent SHCP and STCP - eliminates race conditions during simultaneous load-and-update operations |
| Low static current | ICC ≤ 80 μA at VCC = 5.5 V - reduces quiescent power in always-on modules |
Applications
| Automotive LED Matrix Driver | Body Control Module Data Latch |
|---|---|
|
Use Scenario: Driving 8-channel LED arrays in instrument clusters or ambient lighting systems using SPI-to-parallel conversion. IC Role / Device Role / Timing Role: Serial data receiver and parallel output latch - converts MCU SPI output into stable 8-bit DC drive signals. Use Value: Eliminates need for dedicated GPIO expansion ICs; 3-state outputs allow shared bus control with other peripherals. |
Use Scenario: Holding remote command states (e.g., door lock/unlock, window position) between CAN message reception and actuator execution. IC Role / Device Role / Timing Role: Non-volatile data buffer - retains last valid command during brief MCU sleep cycles or brown-out events. Use Value: MR pin enables synchronous reset across all 8 bits upon system wake-up; automotive temp range ensures reliability in cabin environments. |
| Infotainment Display Backlight Controller | ADAS Sensor Interface Register |
|
Use Scenario: Controlling PWM dimming signals for multi-zone LCD backlighting using serial configuration from application processor. IC Role / Device Role / Timing Role: Timing-critical output register - decouples high-speed serial config from precise PWM timing generation. Use Value: STCP-controlled latch isolation prevents display flicker during serial reconfiguration; <10.5 ns delay ensures sub-microsecond update alignment. |
Use Scenario: Capturing and staging sensor status bits (e.g., radar object detection flags) before batch transfer to host processor. IC Role / Device Role / Timing Role: Edge-aligned data capture register - synchronizes asynchronous sensor interrupts to system clock domain. Use Value: Separate SHCP/STCP clocks allow sensor data sampling at native rate while updating host-visible status on demand - reducing latency jitter. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit serial-to-parallel shift register applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74VHCT595PW-Q100 | TTL-input thresholds (VIH = 2.0 V min), identical pinout and timing | Better compatibility with legacy 5 V TTL microcontrollers; same automotive qualification | Select when interfacing with non-CMOS logic families or older MCUs lacking 3.3 V-tolerant I/O |
| SN74HC595QPWRQ1 | TI's AEC-Q100 Grade 1 variant; slightly higher ICC (160 μA max) and longer tpd (13 ns) | Same functional block diagram but different thermal characteristics and package (TSSOP vs. PW) | Choose if TI ecosystem alignment or specific qualification documentation traceability is required |
Compared with 74VHC595PW-Q100, the 74VHCT595PW-Q100 offers superior noise margin with TTL inputs, while SN74HC595QPWRQ1 trades marginal speed and power efficiency for alternate supply-chain assurance - making the Nexperia part optimal for new designs prioritizing low-latency, low-power automotive interfaces.

FAQ
Can 74VHC595PW-Q100 operate at 3.3 V supply?
Yes - it is fully specified from 2.0 V to 5.5 V. At VCC = 3.3 V, VIH = 2.1 V (min), VOL ≤ 0.36 V (IO = 4 mA), and tpd ≤ 16.5 ns (CL = 50 pF), ensuring reliable interface with 3.3 V microcontrollers and FPGAs without level shifters.
What is the function of the Q7S pin?
Q7S is the serial output of the final stage (Q7) of the shift register, used to cascade multiple 74VHC595PW-Q100 devices. When connected to the DS pin of the next device, it enables daisy-chained expansion of parallel output bits beyond 8, preserving timing integrity across the chain.
How does MR differ from STCP in reset behavior?
MR asynchronously clears only the 8-bit shift register (stages 0–7), leaving the storage register and Q0–Q7 outputs unchanged. STCP transfers data from shift to storage register but does not reset - MR is used for immediate data invalidation; STCP controls deterministic output updates.
Is the TSSOP16 package suitable for reflow soldering?
Yes - SOT403-1 (TSSOP16) is qualified for standard lead-free reflow profiles (J-STD-020). Its side-wettable flanks support automated optical inspection (AOI) of solder joints, and thermal resistance (8.5 mW/K derating above 91 °C) ensures reliability in automotive under-hood thermal cycling.
