Product details
Overview
M74HC175RM13TR from STMicroelectronics is a high-speed CMOS quad D-type flip-flop with asynchronous clear, operating across 2V–6V supply, featuring 16 ns typical propagation delay at 6V, ±4 mA output drive, and 4 µA max quiescent current at 25°C - used in synchronous logic control, clock-domain synchronization, and data latching in industrial PLC I/O modules.
For engineers reviewing the M74HC175RM13TR datasheet, M74HC175RM13TR pinout, M74HC175RM13TR application, or M74HC175RM13TR equivalent, key selection criteria include guaranteed 6V operation, TSSOP-16 package footprint compatibility, asynchronous active-low reset behavior, and verified 125°C extended temperature support per automotive-grade qualification.
Technical Context
The M74HC175RM13TR implements four edge-triggered D flip-flops sharing a common clock and asynchronous clear input, with all inputs and outputs buffered via silicon gate C2MOS technology. It uses positive-edge clock triggering and low-level active reset, ensuring deterministic state initialization independent of clock phase.
Its symmetrical output impedance (|IOH| = IOL ≥ 4 mA) and balanced tPLH/tPHL delays enable reliable interfacing with mixed-voltage logic families. The device meets 28% VCC noise immunity thresholds and supports clean signal transitions up to 61 MHz at 6V with CL = 50 pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2V to 6V - enables direct interface with 3.3V and 5V logic systems without level shifters |
| Propagation Delay (tPD) | 16 ns (typ.) at VCC = 6V - supports >30 MHz clock rates in synchronous latch applications |
| Output Drive Strength | ±4 mA (min.) - sufficient to drive 10 LS-TTL loads or multiple CMOS inputs at full rail |
| Quiescent Current (ICC) | 4 µA (max.) at TA = 25°C - enables ultra-low-power hold states in battery-backed control registers |
| Operating Temperature | −55°C to +125°C - qualified for under-hood automotive and industrial motor-control environments |
| Input Noise Immunity | VNIH/VNIL = 28% VCC (min.) - rejects >1.2V peak noise on 4.5V supply without false triggering |
| Power Dissipation Cap | 500 mW at 65°C - derates linearly to 300 mW at 85°C, supporting continuous operation in sealed enclosures |
Pinout & Package
TSSOP-16 (Thin Shrink Small Outline Package), 4.9 mm × 6.4 mm body, 0.65 mm pitch, 1.2 mm height - optimized for high-density PCB layouts and automated SMT assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CLEAR | Asynchronous master reset (active-low); forces all Q outputs low regardless of clock or D inputs |
| 2, 7, 10, 15 | 1Q, 2Q, 3Q, 4Q | True outputs of flip-flops 1–4; edge-triggered update on rising clock edge |
| 3, 6, 11, 14 | 1Q, 2Q, 3Q, 4Q | Complementary outputs; inverted copies of corresponding Q pins |
| 4, 5, 12, 13 | 1D, 2D, 3D, 4D | Data inputs sampled only on rising clock edge; held stable during setup/hold windows |
| 9 | CLOCK | Positive-edge sensitive clock input; minimum pulse width 6 ns at 6V ensures robust timing margin |
| 8 | GND | Digital ground reference; must be low-impedance connection to minimize switching noise coupling |
| 16 | VCC | Positive supply rail; decoupling capacitor (100 nF) required within 5 mm for stable AC performance |
Key Features
| Feature | Design Value |
|---|---|
| High-Speed Operation | 16 ns typical tPD at 6V enables use in 30+ MHz digital control loops without added timing buffers |
| Wide Supply Range | 2V–6V operation eliminates need for separate voltage regulators in multi-rail embedded systems |
| Asynchronous Reset | Pin 1 CLEAR asserts immediately - critical for fail-safe initialization in safety-critical sequencers |
| ESD Protection | All inputs feature integrated protection diodes rated to ±20 mA - withstands 4 kV HBM ESD events |
| Low-Power Static State | 4 µA ICC max at 25°C reduces standby power in always-on monitoring circuits by >95% vs. bipolar equivalents |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad D-type flip-flop with clear applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC175PW | SOIC-16 package; 20 ns max tPD at 6V; identical logic function and DC specs | Larger footprint; less suitable for space-constrained medical or automotive PCBs | Select when legacy SOIC layout reuse or hand-soldering prototyping is required |
| 74LVC175PW | 3.3V-only supply (1.65–3.6V); faster 3.5 ns tPD; lower 24 mA drive; no 6V tolerance | Not compatible with 5V systems; requires level translation if interfacing with legacy peripherals | Select only in pure 3.3V domains where speed >30 MHz and low capacitance loading are prioritized |
Compared with SN74HC175PW and 74LVC175PW, the M74HC175RM13TR uniquely combines 2–6V operation, TSSOP-16 compactness, and 125°C rating - making it the sole choice for ruggedized, mixed-voltage, high-density control logic where thermal and footprint constraints coexist.

FAQ
Does M74HC175RM13TR support 5V TTL-level inputs?
Yes - its VIH min is 3.15V and VIL max is 1.35V at VCC = 4.5V, fully compatible with standard 5V TTL output thresholds. Input protection diodes clamp to VCC and GND, preventing damage from overshoot beyond absolute max ratings.
Can the CLEAR pin be left unconnected in normal operation?
No - CLEAR is active-low and internally unconnected (floating) by default. Leaving it open risks metastability or unintended reset due to noise coupling. It must be pulled high via ≥10 kΩ resistor to VCC or driven actively.
What is the maximum capacitive load this device can drive reliably?
At 6V supply, the device maintains specified VOL ≤ 0.4V and VOH ≥ 5.6V while sourcing/sinking 5.2 mA. With CL = 50 pF (per AC spec), it supports trace lengths up to 8 cm on FR-4 before signal integrity degrades beyond 10% rise/fall time budget.
Is M74HC175RM13TR pin-compatible with older 74LS175 devices?
Yes - pinout and logic function match 74LS175 exactly, including CLOCK, CLEAR, D inputs, and true/complement Q outputs. However, HC logic draws far less current and operates at higher speeds, so existing LS designs can be upgraded without PCB changes.
