Product details
Overview
74HC164D,652 from Nexperia is an 8-bit serial-in/parallel-out CMOS shift register in SO14 package, featuring dual gated serial inputs (DSA/DSB), asynchronous master reset (MR), and edge-triggered clock (CP) operating from 2.0 V to 6.0 V. It delivers 8 parallel outputs (Q0–Q7), supports -40 °C to +125 °C operation, and enables compact LED driver or GPIO expansion in microcontroller systems.
For engineers reviewing the 74HC164D,652 datasheet, 74HC164D,652 pinout, 74HC164D,652 application, or 74HC164D,652 equivalent, this device is selected for low-power serial-to-parallel data conversion where TTL-level compatibility is not required, supply flexibility matters, and deterministic asynchronous reset is critical.
Technical Context
The 74HC164D,652 implements a synchronous 8-stage D-type flip-flop chain with gated serial data selection logic: either DSA or DSB acts as active-HIGH enable for the other input, allowing flexible serial data routing. Its CP input triggers on LOW-to-HIGH transitions, and MR forces all Q outputs LOW independently of clock or data state.
Input clamp diodes permit safe interfacing to voltages exceeding VCC when used with current-limiting resistors. The device complies with JEDEC JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V), and exhibits latch-up immunity >100 mA per JESD78 Class II Level B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 2.0 V to 6.0 V - supports direct interface with 3.3 V and 5 V logic domains without level shifters |
| Operating temperature | -40 °C to +125 °C - qualified for industrial and extended-temperature embedded control applications |
| Propagation delay (VCC = 4.5 V) | 15 ns typical CP-to-Qn - enables reliable 71 MHz maximum clock frequency at nominal supply |
| Output drive strength | ±4.0 mA at VOH/VOL - sufficient to directly drive LEDs or CMOS inputs without external buffers |
| Input logic type | CMOS-level compatible - VIH = 3.15 V min, VIL = 1.35 V max at VCC = 4.5 V |
| Power dissipation capacitance | 40 pF - used to calculate dynamic power: PD = CPD × VCC² × fi × N |
| ESD protection | HBM >2000 V, CDM >1000 V - enhances robustness in manual handling and board assembly |
Pinout & Package
74HC164D,652 is housed in a plastic small outline package (SO14, SOT108-1) with 14 leads and 3.9 mm body width. Pin 1 is DSA; pin 7 is GND; pin 8 is CP; pin 9 is MR; pin 14 is VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DSA (Pin 1) | Serial data input A | Primary serial input; enabled only when DSB is HIGH - used for data gating and synchronization control |
| DSB (Pin 2) | Serial data input B | Secondary serial input; acts as active-HIGH enable for DSA - allows selective data path activation |
| Q0–Q7 (Pins 3,4,5,6,10,11,12,13) | Parallel output bits | Shift-register stage outputs; Q0 is first-in, Q7 is last-out - provides byte-wide parallel data latching |
| GND (Pin 7) | Ground reference | 0 V return path for all internal logic and output drivers - must be low-impedance for noise immunity |
| CP (Pin 8) | Clock input | Edge-triggered input; data shifts on LOW-to-HIGH transition - defines timing boundary for serial load operations |
| MR (Pin 9) | Master reset | Asynchronous active-LOW signal; clears all Q outputs to LOW regardless of CP or data state - ensures known startup condition |
| VCC (Pin 14) | Positive supply | Primary power rail; powers all internal logic and output stages - requires local 100 nF decoupling near pin |
Key Features
| Feature | Design Value |
|---|---|
| Dual gated serial inputs | DSA and DSB provide hardware-selectable data path control without external logic - reduces PCB routing complexity |
| Asynchronous master reset | MR forces all eight outputs LOW immediately, independent of clock - eliminates race conditions during system initialization |
| Wide supply voltage range | 2.0 V to 6.0 V operation enables single-supply compatibility across 3.3 V and 5 V systems - simplifies power architecture |
| Clamp diode protected inputs | Integrated input clamping permits safe connection to signals up to VCC + 0.5 V using series resistors - avoids external TVS components |
| High noise immunity | CMOS threshold ratios (VIH/VIL) and hysteresis-like behavior reduce susceptibility to EMI-induced glitches - improves reliability in noisy environments |
Applications
| LED Matrix Driver | Microcontroller GPIO Expander |
|---|---|
Use Scenario: Driving 8-segment alphanumeric displays or 8×8 LED matrices in industrial HMI panels. IC Role / Device Role / Timing Role: Serial-to-parallel converter that translates UART or SPI bitstream into parallel column/row enable signals.

IC Role / Device Role / Timing Role: Synchronous shift register aligned to CPU clock domain, with MR driven by reset vector assertion. Use Value: Eliminates need for discrete flip-flops or PALs in retro-computing or industrial retrofit designs - maintains timing integrity across 8-bit bus cycles. |
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 |
|---|---|---|---|
| 74HCT164D,653 | TTL-compatible inputs (VIH = 2.0 V min); identical pinout and function | Better suited for mixed 5 V TTL/CMOS systems where input thresholds must match legacy logic families | Select when interfacing directly to 74LS or 74F series outputs without level translation |
| SN74HC164N | DIP-14 package; same electrical specs but through-hole mounting and wider temperature range (-55 °C to +125 °C) | Preferred for prototyping, educational kits, or high-reliability aerospace test fixtures requiring socketed ICs | Choose for hand-soldered development boards or environments demanding mechanical robustness and thermal margin beyond SO14 |
Compared with 74HC164D,652, the 74HCT164D,653 offers guaranteed TTL input compatibility at 5 V but sacrifices 2.0 V minimum supply support; the SN74HC164N retains full functional equivalence while enabling through-hole assembly and extended cold-temperature operation.

FAQ
What is the maximum clock frequency supported by the 74HC164D,652?
The 74HC164D,652 supports a maximum clock frequency of 85 MHz at VCC = 6.0 V and CL = 50 pF, and 71 MHz at VCC = 4.5 V under the same load. These values are derived from propagation delay (tpd = 12 ns typ at 6.0 V) and are validated across the full -40 °C to +125 °C operating range per Nexperia's Rev. 11 datasheet.
Can DSA and DSB be used simultaneously for data input?
No - DSA and DSB are logically AND-gated: one serves as data input while the other acts as an active-HIGH enable. When DSB = HIGH, DSA data is loaded; when DSA = HIGH, DSB data is loaded. Simultaneous assertion of both as data sources is undefined and violates the function table.
Is the MR (master reset) pin synchronous or asynchronous?
The MR pin is asynchronous and active LOW. It forces all Q0–Q7 outputs to LOW immediately, regardless of CP state or timing - no clock edge is required. This behavior is confirmed in the function table ('Reset (clear)' mode) and functional diagram, and is independent of supply voltage or temperature.
Does the 74HC164D,652 require external pull-up or pull-down resistors on unused inputs?
Unused inputs (DSA, DSB, CP, MR) must be terminated to VCC or GND - floating CMOS inputs cause increased ICC, noise susceptibility, and potential logic contention. Nexperia specifies VIH/VIL thresholds; for example, MR should be pulled HIGH via ≥10 kΩ resistor to prevent unintended reset, and DSB should be tied HIGH if only DSA is used.
