Product details
Overview
74HC175N,652 from Nexperia is a quad positive-edge-triggered D-type flip-flop with asynchronous master reset (MR), 16-pin SO16 package, CMOS-level inputs, and complementary Q/Q̅ outputs per stage. It operates from 2.0 V to 6.0 V across -40 °C to +125 °C and is used in synchronous logic control, data latching, and register file implementation in industrial digital systems.
For engineers reviewing the 74HC175N,652 datasheet, 74HC175N,652 pinout, 74HC175N,652 application, or 74HC175N,652 equivalent, key selection considerations include its 4-channel edge-triggered storage capability, TTL-compatible timing margins at 4.5 V (tpd ≤ 35 ns), MR-driven synchronous clear behavior, and SO16 footprint compatibility with legacy 74-series board layouts.
Technical Context
This device implements four independent D-type latches sharing a common clock (CP) and active-low master reset (MR). Each flip-flop captures the Dn input on the LOW-to-HIGH transition of CP, provided setup (tsu ≥ 14 ns @ VCC = 6.0 V) and hold (th ≥ 4 ns @ VCC = 6.0 V) times are met. Outputs Qn and Q̅n are complementary and driven to valid logic levels within specified propagation delays.
The 74HC175N,652 uses standard CMOS input thresholds (VIH ≥ 3.15 V @ VCC = 4.5 V; VIL ≤ 1.35 V @ VCC = 4.5 V), supports 50 pF load capacitance, and features input clamp diodes enabling interface to voltages exceeding VCC via current-limiting resistors. It complies with JEDEC Std 7A and meets HBM ESD > 2000 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | 74HC high-speed CMOS - ensures low power consumption and noise immunity vs. TTL variants |
| Supply Voltage Range | 2.0 V to 6.0 V - supports battery-powered and mixed-voltage system integration |
| Propagation Delay (tpd) | 16 ns typical @ VCC = 6.0 V, CL = 50 pF - enables reliable operation up to 24 MHz maximum clock frequency |
| Input Thresholds | VIH = 3.15 V min, VIL = 1.35 V max @ VCC = 4.5 V - provides robust noise margin in noisy industrial environments |
| Operating Temperature | -40 °C to +125 °C - qualified for extended-temperature industrial and automotive under-hood applications |
| ESD Rating | HBM > 2000 V - reduces risk of handling damage during assembly and field service |

Pinout & Package
74HC175N,652 is housed in a plastic small outline package (SO16, SOT109-1) with 16 leads and 3.9 mm body width. Pin 1 is marked by a notch or dot; the package is lead-free and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | MR | Asynchronous master reset input (active LOW); forces all Qn outputs LOW regardless of clock state |
| 2, 7, 10, 15 | Q0–Q3 | True outputs of flip-flops 1–4; driven HIGH/LOW based on stored Dn value at clock edge |
| 3, 6, 11, 14 | Q0–Q3 | Complementary outputs; inverted logic state of corresponding Qn pins |
| 4, 5, 12, 13 | D0–D3 | Data inputs; sampled on LOW-to-HIGH CP transition if setup/hold timing is satisfied |
| 8 | GND | Ground reference (0 V); must be low-impedance connection for stable switching performance |
| 9 | CP | Clock input; positive-edge triggered; requires clean, monotonic rising edge to avoid metastability |
| 16 | VCC | Positive supply voltage; decoupling capacitor (100 nF) recommended near pin for noise suppression |
Key Features
| Feature | Design Value |
|---|---|
| Quad D-type flip-flops | Four independent storage elements in one IC reduce board space and interconnect complexity versus discrete solutions |
| Asynchronous master reset | Single MR pin clears all outputs simultaneously without waiting for clock edge - critical for system initialization |
| CMOS input levels | Compatible with 3.3 V and 5 V logic families; eliminates need for level-shifting circuitry in mixed-supply designs |
| Clamp diode protection | Enables safe interfacing to signals exceeding VCC using external current-limiting resistors - simplifies front-end signal conditioning |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT175N,652 | TTL-compatible input thresholds (VIH = 2.0 V min), identical pinout and function | Better suited for direct interfacing with legacy 5 V TTL logic without level shifters | Select when driving from 5 V TTL sources; otherwise 74HC175N,652 offers superior noise margin in mixed-voltage systems |

FAQ
What is the maximum clock frequency supported by the 74HC175N,652?
The 74HC175N,652 supports a maximum clock frequency of 24 MHz at VCC = 4.5 V with CL = 50 pF, as specified in the dynamic characteristics table. At VCC = 6.0 V, fmax reaches 35 MHz under the same load conditions. These values assume proper signal integrity, adequate decoupling, and adherence to setup/hold timing requirements for reliable edge-triggered operation of the 74HC175N,652.
Does the 74HC175N,652 support 3.3 V operation?
Yes, the 74HC175N,652 is fully specified for operation at 3.3 V, with recommended operating conditions listing VCC = 2.0 V to 6.0 V. At 3.3 V, VIH is guaranteed ≥ 2.31 V and VIL ≤ 1.09 V, providing sufficient noise margin for clean interfacing with 3.3 V microcontrollers and FPGAs. All timing parameters, including tpd and fmax, remain valid across this range, confirming robust functionality of the 74HC175N,652 at 3.3 V.
How does the master reset (MR) pin behave in the 74HC175N,652?
The MR pin on the 74HC175N,652 is an asynchronous, active-LOW input that forces all Qn outputs LOW and all Q̅n outputs HIGH immediately upon assertion, independent of the clock signal. Release of MR allows subsequent clock edges to load new data from Dn inputs. This behavior is confirmed in the function table and functional diagram, ensuring deterministic system initialization and fault recovery in the 74HC175N,652.
Is the 74HC175N,652 pin-compatible with older 74LS175 devices?
No, the 74HC175N,652 is not pin-compatible with 74LS175. While both are quad D-type flip-flops with MR and CP inputs, the 74LS175 uses a 16-pin DIP package with different pin assignments (e.g., MR on pin 1, CP on pin 11, Q0 on pin 2), whereas the 74HC175N,652 uses SO16 with MR on pin 1 and CP on pin 9. Direct replacement requires PCB layout revision; however, logic function and timing behavior are compatible when adapted properly for the 74HC175N,652.
What is the power dissipation of the 74HC175N,652 under typical operating conditions?
At VCC = 4.5 V and 25 °C, the 74HC175N,652 draws ≤ 8.0 μA quiescent supply current (ICC), resulting in sub-40 μW static power dissipation. Dynamic power depends on switching frequency and load capacitance, calculated as PD = CPD × VCC² × fi + Σ(CL × VCC² × fo), where CPD = 32 pF. Total power remains well below 500 mW even at maximum rated frequency, ensuring thermal stability in the SO16 package of the 74HC175N,652.
