Product details
Overview
74HCT595D-Q100 from Nexperia is an automotive-grade 8-bit serial-in/serial-or-parallel-out shift register with independent shift and storage registers, 3-state outputs, asynchronous master reset (MR), and TTL-compatible inputs. It operates from -40 °C to +125 °C, supports up to 52 MHz shift clock frequency at VCC = 4.5 V, and delivers 6 mA output drive per Qn pin. It is used in automotive body control modules for LED matrix expansion and multiplexed switch scanning.
For engineers reviewing the 74HCT595D-Q100 datasheet, 74HCT595D-Q100 pinout, 74HCT595D-Q100 application, or 74HCT595D-Q100 equivalent, this page provides verified functional architecture, SO16 package mapping, automotive temperature validation, TTL-level input thresholds, and cascading-ready serial interface behavior - all confirmed against Nexperia's Rev. 4 (2024) product data sheet.
Technical Context
The device implements two synchronized but independently clocked 8-bit registers: a shift register accepting serial data on DS at SHCP rising edges, and a storage register capturing shift register contents on STCP rising edges. Output enable (OE) controls high-impedance state of all eight parallel outputs (Q0–Q7) without affecting internal register states.
MR asynchronously clears only the shift register (not storage), while Q7S enables daisy-chaining by exposing the most recent shifted bit. Input clamp diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors - a key requirement in mixed-voltage automotive subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | 74HCT - TTL-compatible input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 4.5–5.5 V) ensure robust interfacing with legacy microcontrollers. |
| Operating Temperature | -40 °C to +125 °C - Qualified to AEC-Q100 Grade 1, enabling use in under-hood ECUs and powertrain modules. |
| Max Clock Frequency | 52 MHz (typ.) at VCC = 4.5 V - Supports high-speed serial loading for real-time LED refresh or sensor data aggregation. |
| Output Drive | ±6 mA per Qn pin at VCC = 4.5 V - Sufficient to directly drive LEDs or logic inputs without external buffers. |
| Propagation Delay | 24–40 ns (STCP→Qn) - Enables deterministic timing in synchronous control loops with sub-50 ns latency. |
| ESD Rating | HBM > 2000 V, CDM > 1000 V - Meets automotive ESD immunity requirements for assembly and field operation. |
| Supply Voltage | 4.5–5.5 V - Matches standard 5 V automotive rail systems and avoids level-shifting overhead. |
Pinout & Package
74HCT595D-Q100 uses the SO16 (SOT109-1) package: plastic small outline, 16 leads, 3.9 mm body width, gull-wing leads, JEDEC MS-012 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–7, 15 | Q0–Q7 parallel outputs | 8-bit latched data bus; each drives ±6 mA and enters high-Z when OE = HIGH. |
| 8 | GND | Ground reference for all logic and output stages; decoupling capacitor must be placed adjacent. |
| 9 | Q7S serial output | Shift register stage-7 output; enables cascading multiple devices without external wiring. |
| 10 | MR (Master Reset) | Asynchronous active-LOW reset of shift register only; storage register and outputs unaffected. |
| 11 | SHCP (Shift Clock) | Rising-edge-triggered clock for serial data entry into shift register; minimum pulse width 16 ns. |
| 12 | STCP (Storage Clock) | Rising-edge-triggered clock transferring shift register contents to output latches; independent of SHCP. |
| 13 | OE (Output Enable) | Active-LOW control of Q0–Q7 3-state drivers; no effect on internal register states or Q7S. |
| 14 | DS (Data Serial) | Serial data input synchronized to SHCP; accepts TTL-level signals directly from MCUs. |
| 16 | VCC | Positive supply (4.5–5.5 V); must be bypassed with 100 nF ceramic capacitor near pin. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use across -40 °C to +125 °C ambient, including thermal cycling and humidity testing. |
| Independent shift/storage clocks | Enables continuous serial loading (SHCP) while holding stable parallel outputs (STCP-gated), eliminating output glitches. |
| TTL-compatible inputs | Accepts standard 5 V MCU GPIO outputs without level shifters - reduces BOM count and layout complexity. |
| Clamp diode protection | Allows safe connection of DS, SHCP, STCP, MR, OE to voltages > VCC (e.g., 12 V wake-up lines) using series resistors. |
| Daisy-chain capability | Q7S output matches DS timing and voltage levels, enabling reliable multi-device cascading up to 16+ stages. |
Applications
| Automotive LED Matrix Driver | Body Control Module I/O Expander |
|---|---|
|
Use Scenario: Driving 64-LED headlight signature array via SPI-connected MCU with limited GPIO.

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 |
|---|---|---|---|
| 74HC595D-Q100 | CMOS input thresholds (VIH ≥ 3.15 V at VCC = 4.5 V); lower ICC (80 μA vs. 160 μA at VCC = 5.5 V). | Suitable for 3.3 V MCU interfaces with level-shifting; less suited for direct 5 V TTL driver compatibility. | Select when interfacing with 3.3 V logic families or where ultra-low static current is critical. |
| SN74HC595QPWRQ1 | Texas Instruments variant; identical function but different AEC-Q100 test report structure and JEDEC MO-153 package (TSSOP16). | Same automotive qualification, but TSSOP16 footprint requires PCB redesign; thermal resistance differs (91 °C/W vs. 110 °C/W for SO16). | Choose only if TI supply chain alignment or TSSOP16 layout reuse is required; SO16 remains drop-in compatible. |
Compared with 74HC595D-Q100 and SN74HC595QPWRQ1, the 74HCT595D-Q100 uniquely guarantees TTL-level input compatibility at 5 V without external biasing, offers SO16's proven thermal performance in engine bay environments, and maintains identical pinout and timing across Nexperia's Q100 portfolio.

FAQ
Can 74HCT595D-Q100 operate at 3.3 V supply?
No - the 74HCT595D-Q100 is specified only for 4.5–5.5 V operation per its recommended conditions table. At 3.3 V, VIH and VIL thresholds fall outside guaranteed logic levels, risking unreliable input recognition. Use 74HC595D-Q100 instead for 2.0–6.0 V flexibility.
What is the maximum number of 74HCT595D-Q100 devices that can be cascaded reliably?
Up to 16 devices can be cascaded using Q7S→DS connections with proper signal integrity design: maintain <15 pF total load capacitance per stage, use series termination on SHCP/STCP, and limit trace length between Q7S and DS to ≤5 cm. Propagation delay accumulates linearly (max 40 ns × 16 = 640 ns).
Does OE affect Q7S output behavior?
No - the Q7S output is driven solely by the shift register and remains active regardless of OE state. Only Q0–Q7 parallel outputs enter high-impedance mode when OE = HIGH. This allows uninterrupted daisy-chaining even while disabling local outputs.
Is MR pin edge- or level-sensitive?
MR is level-sensitive and asynchronous: a LOW applied to MR immediately clears the shift register contents (sets all stages to 0), independent of SHCP or STCP timing. The storage register, Q0–Q7 outputs, and Q7S remain unchanged until next STCP or SHCP event.
