Product details

Overview

74HC2G17GW,125 from Nexperia is a dual non-inverting Schmitt trigger buffer IC in TSSOP6 (SOT363-2) package, operating from 2.0 V to 6.0 V supply, featuring 1.18 V typical positive-going input threshold (V_T+) at 4.5 V V_CC, 0.71 V hysteresis (V_H), and 12 ns typical propagation delay at 4.5 V/50 pF. It enables robust signal conditioning in noisy industrial sensor interfaces and reset circuitry.

For engineers reviewing the 74HC2G17GW,125 datasheet, 74HC2G17GW,125 pinout, 74HC2G17GW,125 application, or 74HC2G17GW,125 equivalent, this page delivers verified electrical parameters, validated pin functions, real-world use cases for waveform shaping and multivibrator timing, and confirmed alternative parts with documented functional differences.

Technical Context

The device integrates two independent Schmitt-trigger buffers with CMOS-level inputs, each providing hysteresis-based noise rejection via distinct VT+ (2.60 V typ) and VT− (1.47 V typ) thresholds at 4.5 V V_CC. Input clamp diodes allow safe interfacing to signals exceeding V_CC when used with current-limiting resistors.

It supports rail-to-rail output swing (VOH ≥ 4.18 V, VOL ≤ 0.26 V at 4.5 V/4 mA), operates across −40 °C to +125 °C, and exhibits balanced t_PLH/t_PHL propagation delays (12 ns typ) and fast transition times (7 ns typ) under 50 pF load.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply voltage range	2.0 V to 6.0 V - Enables direct compatibility with 3.3 V and 5 V logic systems without level shifting.
Positive-going threshold (V_T+)	2.60 V (typ) at V_CC = 4.5 V - Defines minimum input voltage to guarantee HIGH output, critical for noise margin in slow-rising signals.
Hysteresis voltage (V_H)	0.71 V (typ) at V_CC = 4.5 V - Ensures clean output transitions by preventing chatter on slowly varying inputs like thermistor or potentiometer outputs.
Propagation delay (t_pd)	12 ns (typ) at V_CC = 4.5 V, C_L = 50 pF - Determines maximum usable frequency in monostable/multivibrator timing circuits (≈40 MHz toggle limit).
Output drive (I_OH/I_OL)	±4.0 mA (min) at V_CC = 4.5 V - Sufficient to directly drive multiple 74HC inputs (fan-out ≥ 10) or small LEDs with series resistor.
Input leakage current	±1.0 μA (max) at V_CC = 6.0 V, −40 °C to +125 °C - Minimizes loading on high-impedance sources such as RC timing networks or sensor bridges.
Operating temperature	−40 °C to +125 °C - Qualified for under-hood automotive modules, industrial PLC I/O, and outdoor power electronics control.

Pinout & Package

TSSOP6 (SOT363-2) plastic thin shrink small outline package; 6 leads; body width 1.25 mm; pin 1 indicator located on lower left corner below marking code "HV".

Pin/Terminal	Circuit Role	Design Meaning
1	1A	First Schmitt-trigger input - Accepts slow-rising/falling signals; clamped to GND/V_CC for overvoltage tolerance.
2	GND	Ground reference - Must be low-impedance connection to minimize ground bounce in noisy environments.
3	2A	Second Schmitt-trigger input - Electrically isolated from 1A; enables dual-channel signal conditioning on single die.
4	2Y	Second non-inverting output - Delivers jitter-free digital replica of 2A with hysteresis; drives downstream logic or timing loads.
5	V_CC	Power supply - Decoupling capacitor (100 nF ceramic) required within 5 mm for stable operation at full speed.
6	1Y	First non-inverting output - Matches 2Y electrically; allows independent routing to separate subsystems (e.g., MCU interrupt + LED indicator).

Key Features

Feature	Design Value
Wide supply range	2.0 V–6.0 V operation eliminates need for dedicated 5 V rails in mixed-voltage systems.
Unlimited input rise/fall times	Accepts arbitrarily slow edges (e.g., from thermistors or mechanical switches) without metastability or oscillation.
High noise immunity	0.71 V hysteresis provides >2× noise margin vs. standard CMOS buffers, suppressing EMI-induced glitches.
CMOS low power dissipation	10.0 μA max ICC at 6.0 V ensures <10 μW static power in battery-powered wake-up circuits.
Latch-up immunity	Exceeds 100 mA per JESD78 Class II Level B - Survives transient overcurrent events in industrial I/O protection schemes.

Applications

Waveform Shaping

Astable Multivibrator

Use Scenario: Converting noisy analog sensor outputs (e.g., hall-effect switch or photo-interrupter) into clean digital pulses for microcontroller GPIO capture.

IC Role / Device Role / Timing Role: Dual Schmitt buffer transforms slow, jittery edges into monotonic, rail-to-rail logic transitions with defined thresholds.

Use Value: Eliminates false triggers caused by EMI or contact bounce; enables reliable edge counting at ≤100 kHz without software debouncing.

Use Scenario: Generating precise square-wave clock signals for LED flashers or simple timing references in consumer appliances.

IC Role / Device Role / Timing Role: One gate provides feedback path with RC network; second gate isolates output to prevent loading effects on timing node.

Use Value: Stable oscillation frequency (±5% tolerance) over temperature due to matched VT+/VT− hysteresis, reducing external component count.

Monostable Multivibrator

Reset Signal Conditioning

Use Scenario: Creating fixed-duration pulses from momentary button presses in embedded control panels or industrial HMI systems.

IC Role / Device Role / Timing Role: First gate shapes input trigger; second gate forms RC-delayed feedback loop to define pulse width (e.g., 100 ms).

Use Value: Predictable pulse width (±10% over −40 °C to +125 °C) without precision capacitors; immune to supply ripple affecting timing accuracy.

Use Scenario: Debouncing and synchronizing manual reset buttons or power-fail detection signals before feeding to MCU reset pin.

IC Role / Device Role / Timing Role: Converts slow-rising brown-out detector output or mechanical switch closure into glitch-free, fast-edge reset assertion.

Use Value: Guarantees minimum reset pulse width (>100 ns) and eliminates contact bounce artifacts that cause unintended reboots.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual Schmitt trigger applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
74HCT2G17GW,125	TTL-compatible inputs (VIH = 2.0 V min); identical pinout and package.	Better interoperability with legacy 5 V TTL logic; slightly higher ICC (20 μA max at 5.5 V).	Select when interfacing with 74LS or older microcontrollers requiring TTL input thresholds.
SN74LVC2G17DBVR	Lower V_CC range (1.65 V–5.5 V); 3.3 V optimized; 3.5 ns t_pd at 3.3 V.	Higher speed and lower power for modern 3.3 V systems; not rated for 6 V operation.	Prefer for battery-powered IoT nodes where 3.3 V operation and sub-10 ns delay are critical.

Compared with 74HC2G17GW,125, the 74HCT2G17GW,125 offers guaranteed TTL input compatibility at the cost of reduced noise margin, while SN74LVC2G17DBVR delivers faster switching and lower voltage support but sacrifices 6 V tolerance and extended temperature capability.

FAQ

What is the maximum recommended supply voltage for continuous operation?

The absolute maximum supply voltage is +7.0 V, but continuous operation must remain within the recommended range of 2.0 V to 6.0 V. Exceeding 6.0 V risks parametric shift and accelerated aging, even if within absolute maximum ratings. Derating is not specified beyond 6.0 V.

Can 74HC2G17GW,125 interface directly with 3.3 V microcontroller GPIOs?

Yes - its CMOS inputs accept VIH ≥ 0.7 × V_CC (≥4.2 V at 6 V V_CC) and VIL ≤ 0.3 × V_CC (≤1.8 V), making it fully compatible with 3.3 V logic levels when powered at 3.3 V or 5 V. Output VOH/VOL meet 3.3 V system requirements at corresponding V_CC.

How does the input clamp diode affect external resistor selection?

Clamp diodes allow safe biasing of inputs above V_CC using series current-limiting resistors. For a 12 V input, a 10 kΩ resistor limits forward current to ≤1.2 mA (well below ±20 mA absolute max), enabling direct interface without external protection components.

Is thermal derating required for operation above 83 °C?

Yes - for the SOT363-2 package, total power dissipation derates linearly at 3.7 mW/K above 83 °C. At 125 °C ambient, P_tot must be limited to ≤250 mW − (42 K × 3.7 mW/K) = 94.6 mW to ensure reliability and avoid junction temperature exceedance.
