Product details
Overview
74HCT595DB-Q100 from Nexperia is an automotive-grade 8-bit serial-in, serial-or-parallel-out shift register with storage latch and 3-state outputs, operating from 4.5 V to 5.5 V at -40 °C to +125 °C. It features separate shift (SHCP) and storage (STCP) clocks, asynchronous master reset (MR), and output enable (OE) for bus isolation-used in automotive LED driver interfaces and remote I/O expansion.
For engineers reviewing the 74HCT595DB-Q100 datasheet, 74HCT595DB-Q100 pinout, 74HCT595DB-Q100 application, or 74HCT595DB-Q100 equivalent, key selection criteria include TTL-compatible input thresholds, 3-state parallel output drive capability (±6 mA @ 4.5 V), propagation delay ≤42 ns (STCP→Qn), OE-controlled output disable timing (≤35 ns), and AEC-Q100 Grade 1 qualification.
Technical Context
The device implements two synchronized but independent 8-bit registers: a shift register accepting serial data on DS with LOW-to-HIGH SHCP transitions, and a storage register loaded via LOW-to-HIGH STCP edges. Outputs Q0–Q7 reflect storage register contents only when OE is LOW; MR asynchronously clears the shift register without affecting stored data.
Input clamping diodes allow safe interfacing to voltages beyond VCC using current-limiting resistors. The DHVQFN16 package (SOT763-1) supports AOI via side-wettable flanks and thermal enhancement for automotive under-hood environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures compatibility with 5 V automotive logic rails and stable operation across battery voltage transients. |
| Input Logic Type | TTL-level - accepts standard 5 V microcontroller GPIO outputs without level-shifting. |
| Propagation Delay (STCP→Qn) | Max 60 ns at -40 °C to +125 °C - enables reliable 10 MHz+ update rates for real-time LED or relay bank control. |
| Output Drive (Qn) | ±6 mA @ 4.5 V - directly drives LEDs or logic inputs without external buffers in most automotive I/O applications. |
| 3-State Enable Time (OE→Qn) | Max 53 ns - allows fast bus arbitration and multiplexed peripheral sharing in distributed control modules. |
| AEC-Q100 Grade | Grade 1 (−40 °C to +125 °C) - qualified for engine compartment and powertrain ECU use per automotive reliability standards. |
| ESD Protection | HBM >2000 V, CDM >1000 V - withstands handling and in-system electrostatic events in manufacturing and service environments. |
Pinout & Package
DHVQFN16 plastic dual in-line compatible thermal enhanced very thin quad flat package; no leads; 16 terminals; body 2.5 × 3.5 × 0.85 mm (SOT763-1), with side-wettable flanks for automated optical inspection of solder joints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Q0) | Parallel output stage 0 | LSB of latched 8-bit parallel output; driven only when OE = LOW and STCP has latched latest shift register contents. |
| 2–7 (Q1–Q6) | Parallel output stages 1–6 | Mid-bit outputs mirroring internal storage register; support cascaded LED arrays or segmented display drivers. |
| 8 (GND) | Ground reference | Primary return path for all internal logic and output currents; requires low-impedance PCB connection to minimize noise coupling. |
| 9 (Q7S) | Serial output | MSB of shift register; enables daisy-chaining multiple 74HCT595DB-Q100 devices without external logic. |
| 10 (MR) | Master reset | Asynchronous active-LOW input that clears shift register only-preserves storage register state until next STCP edge. |
| 11 (SHCP) | Shift clock | Edge-triggered input controlling serial data advancement; LOW-to-HIGH transition loads DS into stage 0 and shifts prior bits. |
| 12 (STCP) | Storage clock | Edge-triggered input transferring full 8-bit shift register contents to output latch; decoupled from SHCP for pipeline control. |
| 13 (OE) | Output enable | Active-LOW control for 3-state outputs; high-impedance mode isolates Q0–Q7 from shared bus without altering latch state. |
| 14 (DS) | Serial data input | Single-bit input fed into shift register LSB position on each SHCP rising edge; compatible with SPI MOSI or GPIO bit-banging. |
| 15 (Q7) | Parallel output stage 7 | MSB of latched parallel output; synchronized to STCP, not SHCP-enables deterministic output update timing. |
| 16 (VCC) | Supply voltage | 5 V nominal rail; must be decoupled with ≥100 nF ceramic capacitor near pin to suppress switching noise during output transitions. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 1 certified for continuous operation from −40 °C to +125 °C-validates reliability in engine control, body electronics, and ADAS modules. |
| Separate shift/storage clocks | Enables pipelined operation: new serial data can be shifted in while previous byte remains latched and driving outputs-critical for jitter-free LED dimming or sensor readout. |
| Clamped inputs with current-limiting support | Integrated input clamp diodes allow direct interface to 12 V signals using series resistors-eliminates need for external protection in mixed-voltage automotive subsystems. |
| DHVQFN16 with side-wettable flanks | Enables automated optical inspection (AOI) of solder joints on bottom terminations-improves yield and field reliability in high-volume automotive PCB assembly. |
| 3-state outputs with fast enable/disable | OE-controlled high-impedance state activates in ≤53 ns and deactivates in ≤45 ns-supports time-multiplexed bus sharing among multiple shift registers or peripherals. |

FAQ
Can 74HCT595DB-Q100 operate with a 3.3 V microcontroller?
No-74HCT595DB-Q100 requires VCC between 4.5 V and 5.5 V and features TTL-compatible inputs (VIH ≥2.0 V, VIL ≤0.8 V). While its inputs accept 3.3 V logic HIGH, the device itself cannot be powered from 3.3 V. A level shifter or 5 V supply rail is required for full functionality and AEC-Q100-compliant operation.
What is the maximum recommended clock frequency for SHCP and STCP?
The maximum guaranteed clock frequency is 20 MHz at VCC = 4.5 V and TA = +125 °C (fmax = 20 MHz per Table 7). At 25 °C and VCC = 5.0 V, typical operation reaches 52 MHz. For automotive designs, derate to 20 MHz to ensure timing margin across temperature, voltage, and process variation.
How does MR interact with the storage register during reset?
MR is asynchronous and affects only the shift register-clearing all eight stages to logic LOW. The storage register and its parallel outputs (Q0–Q7) remain unchanged until the next STCP rising edge. This allows safe initialization of serial data flow without disrupting currently displayed or driven outputs.
Is the DHVQFN16 package RoHS and REACH compliant?
Yes-74HCT595DB-Q100 meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Nexperia confirms lead-free termination finish (NiPdAu), halogen-free molding compound, and full substance declaration compliance per customer material declarations and regulatory databases.
