Product details
Overview
74HC175PW,112 from Nexperia is a quad positive-edge-triggered D-type flip-flop with asynchronous master reset (MR), 16-pin TSSOP package, CMOS-level inputs, and complementary Q/Q̅ outputs per stage. It operates from 2.0 V to 6.0 V, supports -40 °C to +125 °C ambient range, and delivers 35 ns typical propagation delay at VCC = 6.0 V - used in synchronous logic control, data latching, and register staging in industrial PLC I/O modules.
For engineers reviewing the 74HC175PW,112 datasheet, 74HC175PW,112 pinout, 74HC175PW,112 application, or 74HC175PW,112 equivalent, this page provides verified functional role, validated timing parameters (tpd, tsu, th, fmax), package-confirmed pin mapping for SOT403-1, and real-world use cases in deterministic digital state management.
Technical Context
This device integrates four independent edge-triggered D flip-flops sharing one clock (CP) and one active-low master reset (MR). Each stage accepts a dedicated Dn input and produces both true (Qn) and inverted (Q̅n) outputs, enabling direct implementation of 4-bit registers without external inverters.
Its CMOS input structure ensures high noise immunity and low static current (ICC ≤ 160 μA at +125 °C), while internal clamp diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors - critical for mixed-voltage board-level signal conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | 74HC - high-speed CMOS compatible with TTL output levels, enabling direct interface to legacy 5 V logic systems |
| Supply Voltage Range | 2.0 V to 6.0 V - supports wide-input industrial rails and battery-backed operation down to 2 V without functional degradation |
| Propagation Delay (tpd) | 35 ns max at VCC = 6.0 V, CL = 50 pF - defines maximum clock-to-output timing budget for 4-bit synchronous latch design |
| Set-up / Hold Time | 17 ns / 5 ns at VCC = 6.0 V - constrains minimum data stability window before and after CP rising edge |
| Max Clock Frequency | 24 MHz at VCC = 6.0 V, CL = 50 pF - sets upper limit for reliable 4-bit parallel load rate in non-critical timing paths |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood industrial control, motor drive feedback registers, and harsh-environment telemetry |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets JEDEC JS-001/JS-002 Class 2/C3 for robust handling during PCB assembly and field service |
Pinout & Package
TSSOP16 plastic thin shrink small outline package (SOT403-1), 16 leads, body width 4.4 mm, 0.65 mm lead pitch - optimized for high-density PCB layouts with thermal performance derating of 8.5 mW/K above +91 °C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (MR) | Asynchronous master reset | Active-LOW global clear: forces all Qn = LOW and Q̅n = HIGH regardless of clock state - essential for power-on initialization and fault recovery |
| 2 (Q0), 7 (Q1), 10 (Q2), 15 (Q3) | True outputs | Register-stored data states; each drives standard CMOS loads up to 4 mA sink/source - usable as bus drivers or state indicators |
| 3 (Q̅0), 6 (Q̅1), 11 (Q̅2), 14 (Q̅3) | Complementary outputs | Logically inverted copies of Qn outputs - eliminates need for external inverters in toggle, enable, or differential signaling paths |
| 4 (D0), 5 (D1), 12 (D2), 13 (D3) | Data inputs | Edge-sampled inputs; data meeting tsu/th relative to CP rising edge is latched - enables synchronous parallel data capture from ADCs or sensor interfaces |
| 8 (GND) | Ground reference | 0 V return path for all internal logic and output stages - must be low-impedance to maintain noise margin and timing integrity |
| 9 (CP) | Clock input | Positive-edge-triggered control signal; LOW-to-HIGH transition initiates sampling and storage - synchronizes all four flip-flops simultaneously |
| 16 (VCC) | Positive supply | Main power rail (2.0–6.0 V); supplies internal logic and output buffers - decoupling capacitor required within 10 mm of pin for stable switching |
Key Features
| Feature | Design Value |
|---|---|
| Quad D-type flip-flop with individual D inputs | Enables compact 4-bit register implementation without external gating or fanout logic - reduces component count in microcontroller peripheral expansion |
| Asynchronous master reset (MR) | Guarantees known initial state across all stages at power-up or error condition - eliminates race conditions in safety-critical sequencing |
| Complementary Q/Q̅ outputs per stage | Provides native differential logic capability - simplifies design of set/reset latches, JK emulation, and dual-rail status monitoring |
| CMOS-level input compatibility | Accepts full-rail input voltages (0 V to VCC) with < ±0.1 μA leakage - ensures interoperability with FPGA I/O banks, DAC outputs, and analog comparators |
| Wide temperature and voltage operation | Validated from -40 °C to +125 °C at 2.0–6.0 V - supports deployment in unregulated power domains and thermally stressed enclosures without derating |
Applications
| Industrial PLC I/O Register | Digital Test Equipment Pattern Generator |
|---|---|
|
Use Scenario: Storing and synchronizing 4-bit parallel sensor status flags (e.g., limit switch, fault, ready, busy) from field devices into a microcontroller's GPIO port. IC Role / Device Role: Synchronous data latch that isolates noisy field wiring from MCU timing domain using MR-initiated clean startup and CP-aligned sampling. Use Value: Eliminates metastability risk via guaranteed setup/hold compliance and provides simultaneous 4-bit readout - reducing firmware polling overhead by 75% vs. bit-banged serial capture. |
Use Scenario: Generating repeatable 4-bit stimulus patterns (e.g., 0000 → 1111 → 0101 → 1010) for IC functional testing on automated test equipment (ATE). IC Role / Device Role: Deterministic pattern sequencer where MR resets to zero and successive CP edges load predefined Dn values from shift register or lookup table. Use Value: Delivers sub-40 ns edge alignment across all four bits - enabling precise timing correlation between stimulus and response measurements at ≤24 MHz clock rates. |
| Motor Drive Fault Latch Array | Legacy Bus Interface Buffer |
|
Use Scenario: Capturing transient overcurrent, overtemperature, and phase-loss fault signals from three-phase inverter gate drivers for persistent reporting to host controller. IC Role / Device Role: Asynchronous fault capture element: MR clears latches on system reset; faults asynchronously assert Dn, then CP strobes them into stable Qn storage. Use Value: Maintains fault history across power cycles when backed by non-volatile memory - avoids loss of critical diagnostic data during brownout events. |
Use Scenario: Interfacing 4-bit status lines from an obsolete 8051-based subsystem to a modern ARM Cortex-M4 host via shared memory-mapped I/O space. IC Role / Device Role: Level-shifting and timing-synchronizing buffer: accepts TTL-compatible inputs (via 74HCT175 variant) and presents clean CMOS outputs aligned to host clock domain. Use Value: Bridges 5 V legacy logic to 3.3 V host without external level translators - preserving signal integrity and reducing BOM cost by two discrete components per channel. |

FAQ
What is the minimum recommended VCC for reliable operation of 74HC175PW,112?
The absolute minimum VCC is 2.0 V per JEDEC specification, and the device guarantees full functionality - including specified tpd, tsu, and th - across -40 °C to +125 °C at this voltage. Below 2.0 V, propagation delays increase nonlinearly and output drive strength degrades; operation below 1.5 V is not characterized and may result in undefined logic states.
Can 74HC175PW,112 be used with 3.3 V microcontroller GPIOs driving its inputs?
Yes: at VCC = 3.3 V, VIH(min) = 2.1 V and VIL(max) = 1.35 V per datasheet Table 6, which aligns with standard 3.3 V CMOS output levels (VOH ≥ 2.4 V, VOL ≤ 0.4 V). No level-shifting is required, and input leakage remains ≤ ±1 μA across temperature - ensuring compatibility with low-drive MCU pins.
Is the master reset (MR) pin truly asynchronous, and does it override clock activity?
Yes: MR is fully asynchronous and active-LOW. When MR transitions to LOW, all Qn outputs immediately go LOW and all Q̅n outputs go HIGH - independent of CP state, timing, or data inputs. This action occurs within tPHL(MR→Q) ≤ 45 ns (VCC = 6.0 V), and no clock edge is required to complete the reset.
Does 74HC175PW,112 support hot insertion or live insertion into a powered backplane?
No: the device lacks hot-swap protection circuitry. Applying VCC before GND, or connecting inputs before supply stabilization, risks violating absolute maximum ratings (e.g., VI > VCC + 0.5 V), potentially causing latch-up or permanent damage. Always follow proper power sequencing: GND first, then VCC, then signals - and use series current-limiting resistors if interfacing to pre-powered systems.
