Product details
Overview
74HC164D,653 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) with propagation delay as low as 12 ns at VCC = 6.0 V and supports industrial temperature range (−40 °C to +125 °C). It is used in LED matrix drivers, I/O expansion for microcontrollers, and serial-to-parallel data conversion in embedded control systems.
For engineers reviewing the 74HC164D,653 datasheet, 74HC164D,653 pinout, 74HC164D,653 application, or 74HC164D,653 equivalent, this page provides verified functional behavior, validated pin mapping for SO14, confirmed timing parameters across voltage/temperature, and real-world use context for serial interface bridging and output expansion-without reliance on generic logic family assumptions.
Technical Context
The device implements an 8-stage D-type flip-flop shift register with synchronous serial loading and asynchronous reset. Data enters via either DSA or DSB, with the other acting as an active-HIGH enable-enabling flexible serial data gating without external logic. The CP input triggers on LOW-to-HIGH transitions, and MR forces all Q outputs LOW independently of clock or data state.
Input clamping diodes allow safe interfacing to voltages exceeding VCC when current-limiting resistors are used. Static characteristics confirm CMOS-level input thresholds (VIH ≥ 3.15 V at VCC = 4.5 V), while dynamic specs include fmax up to 85 MHz at VCC = 6.0 V and tpd ≤ 29 ns under loaded conditions (CL = 50 pF).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | 8-bit serial-in/parallel-out shift register with gated dual data inputs and asynchronous reset |
| Supply Voltage Range | 2.0 V to 6.0 V - enables direct interface with 3.3 V and 5 V logic domains without level translation |
| Propagation Delay (tpd) | 12 ns (typ) at VCC = 6.0 V, CL = 50 pF - supports high-speed serial-to-parallel conversion up to 85 MHz clock rate |

Pinout & Package
74HC164D,653 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 |
|---|---|---|
| 1 (DSA) | Serial data input A | Primary serial data path; enabled only when DSB is HIGH - allows conditional data entry |
| 2 (DSB) | Serial data input B | Secondary serial input and active-HIGH enable for DSA - supports OR-gated serial stream selection |
| 3–6, 10–13 (Q0–Q7) | Parallel output terminals | Eight buffered CMOS outputs; each capable of sourcing/sinking 25 mA - usable for direct LED or relay driver staging |
| 7 (GND) | Ground reference | 0 V return path for all internal logic and output stages - must be low-impedance for stable timing |
| 8 (CP) | Clock input | Edge-triggered (LOW-to-HIGH); controls shift timing - requires clean, monotonic transitions to avoid metastability |
| 9 (MR) | Master reset | Asynchronous active-LOW signal; clears all flip-flops immediately - no clock dependency required for initialization |
| 14 (VCC) | Positive supply | CMOS core and output stage power rail - decoupling capacitor (100 nF) recommended within 10 mm of pin |
Key Features

IC Role / Device Role / Timing Role: Protocol bridge that latches command bytes on CP and presents them as stable Q0–Q7 outputs for address decoding. Use Value: Eliminates need for FPGA or CPLD in simple protocol translation - reduces BOM cost and design complexity for brownfield upgrades. |
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 - higher noise margin in 5 V systems with legacy TTL sources | Preferred where driving from 74LS or older microcontrollers with weak HIGH drive; same SO14 footprint | Select when interfacing with TTL-level sources or when VIH compatibility below 3.15 V is required |
| SN74HC164DR | Same logic function and 2–6 V range, but in SOIC-14 (PW package, SOT402-1) - slightly smaller body (4.4 mm width) and lower thermal resistance | Better suited for space-constrained PCBs; identical timing but different moisture sensitivity classification (MSL-1 vs MSL-3) | Choose for high-density layouts or when JEDEC-standard TSSOP packaging is mandated by assembly process |
Compared with 74HC164D,653, the 74HCT164D,653 offers improved compatibility with legacy 5 V TTL sources, while SN74HC164DR provides identical electrical performance in a thermally enhanced, space-saving TSSOP package - both retain full functional equivalence but differ in input threshold and mechanical form factor.

FAQ
Can 74HC164D,653 operate reliably at 3.3 V supply?
Yes. The 74HC164D,653 is fully specified from 2.0 V to 6.0 V, with guaranteed VIH ≥ 2.4 V and VOL ≤ 0.26 V at VCC = 3.3 V and IO = 4.0 mA. Propagation delay remains ≤ 34 ns (typ) at 3.3 V, making it suitable for 3.3 V microcontroller interfaces without level shifting.
What is the maximum clock frequency supported with 50 pF load capacitance?
At VCC = 6.0 V and CL = 50 pF, the maximum clock frequency is 85 MHz (typ), with minimum pulse width of 10 ns. This is validated per Table 7 in the Nexperia datasheet Rev. 11, and assumes proper PCB layout with minimized trace inductance and local decoupling.
How does the dual-input gating (DSA/DSB) function in practice?
DSA and DSB are logically OR'd internally: data shifts only when one input is HIGH and the other is used as data. For example, holding DSB = HIGH enables serial data entry via DSA; setting DSA = HIGH while DSB carries data achieves the same effect - providing flexibility in signal routing without external logic.
Is the SO14 package (SOT108-1) lead-free and RoHS compliant?
Yes. The 74HC164D,653 in SO14 package meets RoHS Directive 2011/65/EU and is manufactured with lead-free terminations. Nexperia confirms compliance in its official product change notices and material declarations, with solder reflow profile aligned to JEDEC J-STD-020 Class 3A.
