Product details
Overview
74AHC595D-Q100 from Nexperia is an automotive-grade 8-bit serial-in/parallel-out shift register with separate shift and storage registers, 3-state outputs, asynchronous master reset (MR), and TTL-compatible input variants. It operates from 2.0 V to 5.5 V, supports −40 °C to +125 °C, and enables cascaded LED driver or GPIO expansion in vehicle body control modules.
For engineers reviewing the 74AHC595D-Q100 datasheet, 74AHC595D-Q100 pinout, 74AHC595D-Q100 application, or 74AHC595D-Q100 equivalent, key selection criteria include its dual-clock architecture (SHCP/STCP), overvoltage-tolerant inputs (to 5.5 V), AEC-Q100 Grade 1 qualification, and SO16 package compatibility with legacy PCB footprints.
Technical Context
This device implements a two-stage pipeline: an 8-bit shift register accepting serial data on SHCP rising edges, and an independent 8-bit storage register loaded on STCP rising edges-enabling glitch-free output updates. The MR input asynchronously clears only the shift register, preserving storage register contents until next STCP.
Its 3-state outputs are controlled by OE (active LOW), with no effect on internal register states. Input Schmitt triggers provide high noise immunity, while overvoltage tolerance (up to 5.5 V) allows safe interfacing with mixed-voltage systems-even when VCC = 3.3 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | 8-bit serial-in/parallel-out shift register with output latches and 3-state outputs |
| Supply Voltage Range | 2.0 V to 5.5 V - supports both 3.3 V and 5 V logic domains without level shifters |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive applications per AEC-Q100 Grade 1 |
| Max Clock Frequency | 170 MHz at VCC = 5.5 V - enables high-speed data loading for real-time lighting or sensor interface |
| Propagation Delay | 4.0 ns (SHCP→Q7S, VCC = 5.5 V, CL = 15 pF) - ensures tight timing margins in synchronous control chains |
| Input Voltage Tolerance | Up to 5.5 V regardless of VCC - eliminates external clamping diodes in mixed-supply designs |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets automotive robustness requirements for assembly and field operation |

| 8 | GND | Reference ground for all logic and power domains |
| 9 | Q7S serial output | Shift register MSB output for daisy-chaining multiple devices |
| 10 | MR (Master Reset) | Asynchronous active-LOW reset of shift register only; no effect on storage register |
| 11 | SHCP (Shift Clock) | Rising-edge-triggered clock for serial data entry into 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 3-state outputs; does not affect internal register states |
| 14 | DS (Data Serial input) | Serial data input synchronized to SHCP rising edge |
| 16 | VCC | Positive supply rail (2.0–5.5 V); powers logic and output drivers |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent clocks | SHCP and STCP allow decoupled data shifting and output updating - prevents output glitches during load operations |
| Overvoltage-tolerant inputs | All inputs withstand up to 5.5 V regardless of VCC - simplifies interconnection with higher-voltage microcontrollers or sensors |
| AEC-Q100 Grade 1 qualification | Validated for automotive use from −40 °C to +125 °C - suitable for body electronics, lighting, and infotainment peripherals |
| 3-state outputs with OE control | Outputs enter high-impedance state when OE = HIGH - enables bus sharing and multi-device parallel driving |
| Schmitt-trigger inputs | Provides > 0.5 V hysteresis on all control inputs - rejects noise on long traces or noisy automotive environments |
Applications
| LED Driver Expansion | Automotive Body Control Unit |
|---|---|
Use Scenario: Driving 8-channel LED arrays in headlamp or interior lighting modules using MCU GPIO-limited interfaces. IC Role / Device Role / Timing Role: Serial-to-parallel converter translating SPI-like bitstreams into simultaneous 8-bit output enables, with STCP-synchronized update to avoid flicker. Use Value: Reduces MCU pin count by 7+ while maintaining precise, jitter-free LED on/off timing via separated SHCP/STCP clocks. | Use Scenario: Managing door lock actuators, window lift motors, and mirror controls in centralized body domain controllers. IC Role / Device Role / Timing Role: GPIO expander providing isolated, latch-protected outputs with MR-initiated safe default state on power-up or fault. Use Value: Enables fail-safe behavior: MR resets shift register on brown-out, preventing unintended actuator activation during voltage recovery. |
| Industrial Sensor Interface Hub | Dashboard Display Backlight Control |
Use Scenario: Aggregating status signals from multiple CAN/LIN-connected sensors before forwarding to main ECU via parallel bus. IC Role / Device Role / Timing Role: Parallel-output latch holding sensor state between polling intervals; OE allows dynamic bus arbitration with other peripherals. Use Value: Eliminates need for continuous polling - storage register retains last-read values, reducing MCU interrupt load and system power. | Use Scenario: Controlling individual CCFL or LED backlight segments in digital instrument clusters requiring dimming and fault reporting. IC Role / Device Role / Timing Role: Output latch holding PWM-modulated brightness levels; Q7S enables daisy-chained fault flag propagation across display zones. Use Value: Supports zone-specific brightness tuning and open-load detection via serial feedback path without additional I/O pins. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit shift register applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT595D-Q100 | TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max) vs. CMOS thresholds in AHC variant | Better suited for direct connection to legacy 5 V TTL microcontrollers without level translation | Select when interfacing with older 5 V logic families; otherwise AHC offers wider VCC range and lower static current |
| SN74HC595QPWRQ1 | TI's AEC-Q100 Grade 1 variant with identical function but different AC specs: tpd = 18 ns (max) at 6 V, fmax = 25 MHz (vs. 170 MHz) | Limited speed makes it unsuitable for high-refresh-rate LED or fast sensor sampling applications | Prefer for cost-sensitive, low-speed automotive functions where TI supply chain preference exists; avoid for timing-critical paths |
Compared with 74AHCT595D-Q100, this AHC version delivers superior noise immunity and broader supply flexibility; versus SN74HC595QPWRQ1, it provides >6× higher maximum clock rate and tighter propagation delay control-critical for deterministic real-time peripheral control.

FAQ
Can 74AHC595D-Q100 operate at 2.5 V supply?
Yes. The device is fully specified from 2.0 V to 5.5 V, with guaranteed VIH/VIL thresholds, propagation delays, and output drive strength down to 2.0 V. At 2.5 V, VOH remains ≥2.1 V and VOL ≤0.36 V under 4 mA load, supporting reliable interfacing with 2.5 V microcontrollers.
What happens to Q0–Q7 outputs during MR assertion?
Asserting MR (LOW) resets only the shift register; the storage register and Q0–Q7 outputs remain unchanged until the next STCP rising edge. Outputs retain their last latched state, ensuring no unintended transitions occur during reset-critical for safety-critical actuator control.
Is the SO16 package RoHS and REACH compliant?
Yes. The SOT109-1 package used for 74AHC595D-Q100 is lead-free, RoHS-compliant, and conforms to REACH SVHC regulations. Nexperia's product change notifications confirm full compliance with EU directives, including exemption 7a for lead in high-melting-temperature solder alloys.
How does Q7S enable cascading with another 74AHC595D-Q100?
Q7S carries the MSB shifted out of the first device's shift register. Connecting Q7S to DS of the second device, with shared SHCP and STCP lines, creates a 16-bit shift chain. Data enters the first device's DS, propagates through both shift registers on each SHCP edge, then loads into both storage registers on STCP-enabling seamless expansion.
