Product details
Overview
74AHC164D-Q100 from Nexperia is an AEC-Q100 Grade 1 qualified 8-bit serial-in/parallel-out shift register in SO14 package, featuring dual serial inputs (DSA/DSB), eight CMOS-level parallel outputs (Q0–Q7), edge-triggered clock (CP), and active-low master reset (MR). It operates from 2.0 V to 5.5 V across –40 °C to +125 °C and supports mixed-voltage translation via overvoltage-tolerant inputs up to 5.5 V. Used in automotive lighting control and body electronics for expanding GPIOs.
For engineers reviewing the 74AHC164D-Q100 datasheet, 74AHC164D-Q100 pinout, 74AHC164D-Q100 application, or 74AHC164D-Q100 equivalent, this page delivers verified functional identity, automotive-grade thermal and voltage specs, SO14 pin mapping, real-world use cases in vehicle subsystems, and validated alternatives with documented electrical and interface differences.
Technical Context
The device implements a synchronous 8-stage shift register with dual-input data selection logic: either DSA or DSB can serve as active-HIGH enable for the other, enabling flexible serial data routing. Data shifts on LOW-to-HIGH transitions of CP, and MR asynchronously clears all outputs to LOW independent of clock or data state.
All inputs include Schmitt-trigger action for noise immunity, and the CMOS-level input thresholds (VIH = 3.85 V min at VCC = 5.5 V; VIL = 1.65 V max) ensure robust operation in noisy automotive environments. Overvoltage tolerance (inputs rated to 5.5 V regardless of VCC) allows safe interfacing with 5 V controllers while powered from 3.3 V rails.
Key Specifications

Pinout & Package
74AHC164D-Q100 uses the SO14 (SOT108-1) plastic small outline package: 14-pin, 3.9 mm body width, 1.27 mm lead pitch, gull-wing leads. Thermal performance supports continuous operation at +125 °C ambient with linear derating above 100 °C (10.1 mW/K).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (DSA) | Serial data input A | Primary serial input; functions as active-HIGH enable when DSB is used for data |
| 2 (DSB) | Serial data input B | Secondary serial input; functions as active-HIGH enable when DSA is used for data |
| 3 (Q0) | Parallel output 0 | LSB of shifted data; updates on first CP rising edge after load |
| 4 (Q1) | Parallel output 1 | Second bit; advances one position per CP edge |
| 5 (Q2) | Parallel output 2 | Third bit; part of contiguous Q0–Q7 parallel bus |
| 6 (Q3) | Parallel output 3 | Fourth bit; supports byte-aligned readout in microcontroller interfaces |
| 7 (GND) | Ground reference | 0 V return path; must be low-impedance for stable timing and noise immunity |
| 8 (CP) | Clock input | LOW-to-HIGH edge-triggered; defines shift timing; Schmitt-triggered for slow-rising signals |
| 9 (MR) | Master reset | Asynchronous active-LOW; forces all Q0–Q7 to LOW immediately, overriding CP and data |
| 10 (Q4) | Parallel output 4 | Fifth bit; maintains consistent propagation delay relative to CP |
| 11 (Q5) | Parallel output 5 | Sixth bit; matches Q0–Q3 timing specs within ±0.5 ns |

| 13 (Q7) | Parallel output 7 | MSB of 8-bit register; final stage output; critical for end-of-shift detection |
| 14 (VCC) | Supply voltage | Power rail (2.0–5.5 V); decoupling capacitor (100 nF) required within 5 mm of pin |
Key Features
| Feature | Design Value |

Applications
| Automotive LED Lighting Control | Body Control Module (BCM) I/O Expansion |
|---|---|
Use Scenario: Driving 8-channel LED arrays in headlamp or tail lamp assemblies using a single microcontroller SPI line.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit serial-in/parallel-out shift register applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT164D-Q100 | TTL-compatible inputs (VIH = 2.0 V min), otherwise identical timing, packaging, and automotive qualification | Better suited for legacy 5 V controller interfaces requiring TTL threshold compatibility | Select when interfacing with older microcontrollers lacking CMOS-level output swing |
| SN74LV164AQPWRQ1 | TI's AEC-Q100 Grade 1 variant; wider VCC range (1.65–5.5 V); higher ICC (max 100 μA vs. 80 μA) | Supports 1.8 V logic domains; slightly higher static current may impact ultra-low-power sleep modes | Choose for designs requiring 1.8 V compatibility or TI ecosystem alignment |
Compared with 74AHC164D-Q100, the 74AHCT164D-Q100 offers TTL input thresholds for backward compatibility but sacrifices some noise margin, while SN74LV164AQPWRQ1 extends low-voltage operation at the cost of higher quiescent current - both require layout review for timing closure due to minor tpd variations.

FAQ
What is the maximum clock frequency supported by the 74AHC164D-Q100?
The device supports up to 175 MHz maximum clock frequency at VCC = 5.0 V and CL = 15 pF, with typical propagation delay of 4.5 ns. At 50 pF load and VCC = 5.0 V, fmax drops to 115 MHz. These values are guaranteed across –40 °C to +125 °C per AEC-Q100 testing, and require proper PCB layout with controlled impedance and minimized trace capacitance.
Can DSA and DSB be used simultaneously for data input?
No - DSA and DSB are not dual-data lanes. One serves as data input while the other acts as an active-HIGH enable for that data path. For example, if DSB is held HIGH, data on DSA is loaded on each CP rising edge; if DSA is HIGH, data on DSB is loaded. Simultaneous assertion of both as data sources is undefined and violates the function table.
How does the master reset (MR) interact with the clock (CP) during operation?
MR is asynchronous and dominant: a LOW on MR forces Q0–Q7 to LOW immediately, regardless of CP state, DSA/DSB levels, or current register contents. The reset is transparent - no clock edge is needed - and recovery occurs on the next valid CP edge after MR returns HIGH, with new data shifting in from DSA or DSB as enabled.
Is the SO14 package (SOT108-1) lead-free and RoHS compliant?
Yes - the 74AHC164D-Q100 in SO14 package is manufactured per Nexperia's standard RoHS-compliant process, with lead-free matte tin terminations and halogen-free molding compound. It meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) and is compatible with standard SnPb and lead-free reflow profiles.
