Product details
Overview
74VHCT595D-Q100 from Nexperia is an automotive-grade 8-bit serial-in/parallel-out shift register with storage latch and 3-state outputs, pin-compatible with LSTTL. It features separate shift (SHCP) and storage (STCP) clocks, asynchronous master reset (MR), and TTL-level input compatibility (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V). Operates from −40 °C to +125 °C in SO16 package and supports serial-to-parallel data conversion in automotive body control modules.
For engineers reviewing the 74VHCT595D-Q100 datasheet, 74VHCT595D-Q100 pinout, 74VHCT595D-Q100 application, or 74VHCT595D-Q100 equivalent, key selection criteria include TTL-input compatibility, AEC-Q100 Grade 1 qualification, 3-state output enable timing (ten ≤ 14.5 ns), and cascading capability via Q7S serial output.
Technical Context
This device implements two synchronous register stages: an 8-bit shift register clocked on SHCP rising edges and a parallel-output storage register clocked on STCP rising edges. The separation enables independent data shifting and latched output update-critical for glitch-free LED or relay driver control in automotive ECUs.
All inputs feature Schmitt-trigger action for noise immunity, accept voltages up to 7.0 V regardless of VCC, and support mixed-voltage interfacing. Output drivers deliver ±8 mA drive strength with VOL ≤ 0.55 V and VOH ≥ 3.70 V at VCC = 4.5 V, ensuring robust logic-level translation in noisy vehicle environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | 74VHCT - TTL-compatible CMOS, enabling direct interface with legacy microcontrollers without level shifters |
| Operating Temperature | −40 °C to +125 °C - Qualified per AEC-Q100 Grade 1 for under-hood automotive applications |
| Max Clock Frequency | 90 MHz at VCC = 4.5–5.5 V - Supports high-speed serial loading in real-time lighting or sensor data acquisition |
| Propagation Delay | tPD ≤ 12.5 ns (STCP→Qn, CL = 50 pF, VCC = 4.5–5.5 V) - Enables sub-100 ns output update latency for time-critical actuation |
| Output Drive | ±8 mA per output - Sufficient to directly drive LEDs, small relays, or logic inputs without external buffers |

Pinout & Package
Package: SO16 (SOT109-1), plastic small outline, 16-pin, 3.9 mm body width, lead pitch 1.27 mm.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1–7, 15 | Parallel outputs Q0–Q7 | 8-bit latched data bus; 3-state controlled by OE; used for driving displays, GPIO expanders, or relay arrays |
| 8 | GND | Ground reference for all internal logic and output drivers; must be low-impedance for noise suppression |
| 9 | Q7S | Serial output for daisy-chaining multiple devices; enables expansion beyond 8 bits without additional MCU pins |
| 10 | MR | Asynchronous master reset (active LOW); clears shift register only - preserves storage register contents until next STCP |
| 11 | SHCP | Shift register clock input (rising-edge triggered); controls serial data entry into the 8-stage shift path |
| 12 | STCP | Storage register clock input (rising-edge triggered); transfers current shift register contents to output latches |
| 13 | OE | Output enable (active LOW); places Q0–Q7 in high-impedance state for bus sharing or power saving |
| 14 | DS | Serial data input; accepts TTL-level signals; Schmitt-triggered for reliable operation in noisy automotive harnesses |
| 16 | VCC | Positive supply (4.5–5.5 V); powers both shift and storage registers plus output drivers |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for continuous operation at +125 °C ambient - suitable for engine control units and transmission modules |
| TTL-level input thresholds | VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V - ensures interoperability with legacy 5 V microcontrollers and sensors |
| Separate SHCP and STCP clocks | Enables pipelined operation: new data can be shifted in while previous data remains latched and active on outputs |
| Schmitt-trigger inputs | Provides hysteresis (typ. 0.4 V) on DS, SHCP, STCP, MR, OE - rejects noise spikes common in automotive 12 V systems |
| Side-wettable flanks not applicable | SO16 package (SOT109-1) lacks side-wettable flanks - AOI inspection requires top-surface solder joint evaluation only |
Applications
| Automotive Body Control Unit | LED Matrix Display Driver |
|---|---|
Use Scenario: Centralized control of door locks, window lifts, and interior lighting via CAN-connected MCU with limited GPIO. IC Role / Device Role / Timing Role: Serial-to-parallel converter expanding MCU's output capability; Q0–Q7 drive MOSFET gates or optocouplers with precise STCP-synchronized updates.

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 |
|---|---|---|---|
| SN74HC595QPWRQ1 | CMOS input thresholds (VIH = 3.85 V min), lower max fmax (70 MHz), same SO16 package | Requires 3.3 V or 5 V logic source with higher VIH; less suitable for mixed-voltage 5 V systems with marginal noise margins | Select when interfacing with 3.3 V MCUs or where lower dynamic power (CPD = 150 pF) is prioritized over speed |
| MC74VHC595DT | Non-automotive grade (no AEC-Q100), wider VCC range (2.0–5.5 V), identical pinout and function | Not qualified for automotive use; unsuitable for production in vehicles but acceptable for prototyping or industrial control | Select for cost-sensitive non-automotive designs requiring same functionality without qualification overhead |
Compared with SN74HC595QPWRQ1 and MC74VHC595DT, the 74VHCT595D-Q100 uniquely combines TTL input compatibility, AEC-Q100 Grade 1 qualification, and 90 MHz operation - making it the only choice for production automotive systems requiring robust 5 V interfacing and high-speed serial expansion.

FAQ
Can 74VHCT595D-Q100 operate at 3.3 V supply?
No. The 74VHCT595D-Q100 is specified only for VCC = 4.5 V to 5.5 V per Table 5. Its TTL-input thresholds (VIH = 2.0 V min) are optimized for 5 V systems; operation below 4.5 V violates recommended conditions and risks unreliable input recognition and reduced noise margin.
What is the purpose of separate SHCP and STCP clocks?
Separate clocks enable pipelined operation: SHCP shifts new data into the shift register while STCP independently latches that data to the output pins. This prevents output glitches during serial loading and allows continuous data streaming with deterministic, edge-aligned output updates - essential for synchronized LED or relay control.
Does MR (Master Reset) affect the storage register outputs?
No. MR asynchronously clears only the 8-bit shift register (stages 0–7); it has no effect on the storage register or Q0–Q7 output states. Outputs retain their last latched values until the next STCP pulse, enabling safe reset of serial input pipeline without disrupting active peripheral control.
Is the SO16 package RoHS and REACH compliant?
Yes. The 74VHCT595D-Q100 in SO16 (SOT109-1) package complies with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, including restrictions on lead, cadmium, mercury, hexavalent chromium, PBB, PBDE, and SVHC substances - confirmed in Nexperia's official compliance documentation.
