Product details
Overview
74VHCT595PW-Q100 from Nexperia is an automotive-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), TTL-compatible inputs, and 8 parallel bus-driver outputs enabled by active-low OE. Used in automotive lighting control and dashboard display drivers where cascaded serial-to-parallel data conversion is required.
For engineers reviewing the 74VHCT595PW-Q100 datasheet, 74VHCT595PW-Q100 pinout, 74VHCT595PW-Q100 application, or 74VHCT595PW-Q100 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, 5 V TTL-level input compatibility, 3-state output drive capability, and TSSOP16 package suitability for high-density automotive PCB layouts.
Technical Context
This device implements two synchronized but independent 8-bit register stages: a serial shift register accepting data on SHCP rising edges and a parallel storage register loaded on STCP rising edges. The separation enables precise timing control between data capture and output update-critical for glitch-free LED matrix or relay bank sequencing.
Its TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V) ensure robust interfacing with legacy microcontrollers and logic families, while Schmitt-trigger action on all inputs suppresses noise on long traces in harsh automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - matches standard automotive 5 V rail; supports operation across battery voltage fluctuations without level-shifting. |
| Input Logic Type | TTL-level compatible - interfaces directly with 5 V MCU GPIOs and legacy controllers without external translators. |
| Max Clock Frequency | 130 MHz (min) at VCC = 4.5–5.5 V - enables >7.7 Mbps serial data loading for real-time display updates. |
| Propagation Delay | 4.0 ns (typ) SHCP→Q7S, 4.2 ns (typ) STCP→Qn - ensures sub-10 ns timing margins for synchronous multi-device cascading. |
| Output Drive | ±8 mA (min) at VCC = 4.5 V - sufficient to directly drive LEDs or small-signal MOSFET gates without external buffers. |
| Temperature Range | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and instrument cluster applications. |
| ESD Rating | HBM >2000 V, CDM >1000 V - withstands handling and board assembly stresses in automotive manufacturing lines. |
Pinout & Package
TSSOP16 plastic thin shrink small outline package (SOT403-1), 16-lead, body width 4.4 mm, lead pitch 0.65 mm - optimized for automated optical inspection (AOI) and high-density routing in automotive ECUs.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Q0 | Parallel output stage 0 - lowest-order bit of latched 8-bit data; used for LSB-aligned peripheral control. |
| 2–7 | Q1–Q6 | Parallel outputs stages 1–6 - provide sequential bit positions for driving segmented displays or I/O expanders. |
| 8 | GND | Ground reference - must be low-impedance connection to minimize switching noise coupling into analog subsystems. |
| 9 | Q7S | Serial output - feeds next device in daisy-chain; enables unlimited expansion of parallel outputs via single data line. |
| 10 | MR | Master reset (active LOW) - asynchronously clears shift register only; leaves storage register unchanged until next STCP. |
| 11 | SHCP | Shift clock input - rising-edge triggered; controls serial data entry rate and determines maximum throughput speed. |
| 12 | STCP | Storage clock input - rising-edge triggered; transfers latest 8-bit pattern from shift register to output latches. |
| 13 | OE | Output enable (active LOW) - places all Q0–Q7 outputs in high-impedance state; enables bus sharing and power gating. |
| 14 | DS | Serial data input - accepts new bit on each SHCP rising edge; supports continuous streaming or burst-mode loading. |
| 15 | Q7 | Parallel output stage 7 - MSB of latched data; often used for critical status flags or high-priority control signals. |
| 16 | VCC | Supply voltage - decoupling capacitor (100 nF ceramic) required within 5 mm for stable high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient - eliminates need for additional qualification testing in Tier 1 designs. |
| Separate SHCP and STCP clocks | Enables pipelined operation: new data can be shifted in while previous data remains latched and stable on outputs. |
| 3-state parallel outputs with OE control | Allows multiple 74VHCT595PW-Q100 devices to share a common bus or driver stage without contention. |
| Schmitt-trigger inputs | Provides >0.8 V hysteresis on all control pins - rejects EMI-induced glitches on noisy vehicle harnesses. |
| TTL-compatible input thresholds | Accepts standard 5 V logic levels without level translation - simplifies interface with legacy MCUs and ASICs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit shift register with storage latch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74VHC595PW-Q100 | CMOS-level inputs (VIH = 3.85 V min); lower ICC (4 μA typ) but incompatible with 3.3 V TTL outputs. | Better for mixed-voltage systems with 3.3 V MCUs and level-shifted control lines. | Select when interfacing with CMOS logic families or ultra-low static power is prioritized over TTL compatibility. |
| SN74HC595QPWRQ1 | Texas Instruments part; identical function but different AEC-Q100 test report structure and JEDEC package variant (TSSOP-16, SOT-403-1 equivalent). | Same automotive temperature range and pinout; differs in ESD rating (HBM 4 kV vs. 2 kV) and propagation delay variance. | Choose for TI-design ecosystems or when higher HBM tolerance is required for specific assembly processes. |
Compared with 74VHC595PW-Q100, this part offers TTL-level input compatibility essential for legacy 5 V controller integration, while SN74HC595QPWRQ1 provides marginally higher ESD robustness but requires validation of timing skew in high-speed cascades.

FAQ
Can 74VHCT595PW-Q100 operate at 3.3 V supply?
No. The 74VHCT595PW-Q100 is specified only for 4.5 V to 5.5 V operation per its recommended conditions table. At 3.3 V, input thresholds fall outside TTL specification (VIH minimum becomes undefined), and output drive strength degrades below guaranteed levels. Use 74VHC595PW-Q100 for 3.3 V systems with CMOS-level inputs.
What is the purpose of separate SHCP and STCP clocks?
Separate clocks enable pipelined operation: new data shifts into the shift register on SHCP edges while previously shifted data remains held in the storage register until explicitly transferred on STCP. This prevents output glitches during data loading and allows continuous serial input without disrupting active outputs.
How does the MR (master reset) pin affect outputs?
MR asynchronously clears only the 8-bit shift register (stages 0–7); it does not affect the storage register or Q0–Q7 outputs. Outputs retain their last latched value until the next STCP pulse. This allows safe initialization of serial data flow without disturbing active peripheral states.
Is Q7S output synchronized to SHCP or STCP?
Q7S is strictly synchronous to SHCP - it reflects the state of internal shift register stage 6 on each SHCP rising edge, with propagation delay tpd(SHCP→Q7S). It is independent of STCP and OE, making it reliable for daisy-chaining regardless of storage register or output enable state.
