Product details

Overview

74HC2G14GV,125 from Nexperia is a dual inverting Schmitt trigger IC in SC-74 (SOT457) package, providing two independent hysteresis-enabled inverters with CMOS-level inputs, 2.0–6.0 V supply range, and operation up to +125 °C - used for noise-immune signal conditioning in industrial sensor interfaces and relaxation oscillators.

For engineers reviewing the 74HC2G14GV,125 datasheet, 74HC2G14GV,125 pinout, 74HC2G14GV,125 application, or 74HC2G14GV,125 equivalent, key selection criteria include input hysteresis voltage (min 0.3 V at VCC = 2.0 V), propagation delay (13–190 ns depending on VCC and load), output drive capability (±4.0 mA at VCC = 4.5 V), operating temperature range (−40 °C to +125 °C), and SC-74 package compatibility with high-density PCB layouts.

Technical Context

This device implements two independent Schmitt-trigger inverters with input clamp diodes enabling safe interfacing to signals exceeding VCC when current-limiting resistors are used. Each channel transforms slow-rising/falling analog-like inputs into clean digital outputs via defined VT+ (positive-going threshold) and VT− (negative-going threshold) levels.

The hysteresis (VH = VT+ − VT−) ranges from 0.30 V to 1.70 V across VCC (2.0–6.0 V) and temperature (−40 °C to +125 °C), ensuring robust noise rejection. Propagation delays are balanced between channels and specified under controlled CL = 50 pF loading, supporting reliable timing in monostable and astable multivibrator configurations.

Key Specifications

Parameter	Value and Actual Design Meaning
Function	Dual inverting Schmitt trigger - provides two independent hysteresis-based logic inversion paths
Supply Voltage Range	2.0 V to 6.0 V - supports direct interface with 3.3 V and 5 V systems without level shifting
Hysteresis Voltage (VH)	0.30 V (min) to 1.70 V (max) - ensures ≥300 mV noise margin across full VCC and temperature range
Propagation Delay (tpd)	13 ns (typ) at VCC = 6.0 V, CL = 50 pF - enables use in sub-50 MHz digital timing circuits
Output Drive	±4.0 mA (min) at VCC = 4.5 V - sufficient to directly drive TTL loads or small capacitive nets
Operating Temperature	−40 °C to +125 °C - qualified for extended industrial and under-hood applications
Input Capacitance (CI)	2.0 pF (max) - minimizes loading on high-impedance source signals such as RC networks

Pinout & Package

SC-74 (SOT457) plastic surface-mounted package: 6-pin, 1.7 mm × 2.5 mm body, 0.95 mm height, 0.65 mm pitch, pin 1 indicator in lower-left corner below marking "H14".

Pin/Terminal	Circuit Role	Design Meaning
1A	Data input (Channel 1)	Schmitt-triggered inverter input - accepts slow edges; clamped to GND/VCC via internal diodes
2	GND	Ground reference for all logic and power domains - must be low-impedance connection
2A	Data input (Channel 2)	Independent Schmitt input - electrically isolated from Channel 1 except shared supply rails
2Y	Data output (Channel 2)	Inverted, jitter-free output - drives loads up to ±4.0 mA with rail-to-rail swing
VCC	Supply voltage	Primary power rail - decoupling capacitor (100 nF) required within 5 mm of pin
1Y	Data output (Channel 1)	Complementary output to 1A - matches 2Y in timing and drive strength

Key Features

Feature	Design Value
Wide supply range	2.0–6.0 V operation - eliminates need for separate voltage regulators in mixed-supply systems
Input clamp diodes	Enables safe overvoltage tolerance (VI > VCC) when series current-limiting resistors are used
Unlimited input edge rates	Accepts arbitrarily slow rise/fall times - critical for RC-based timing and sensor signal conditioning
High noise immunity	Guaranteed hysteresis ≥0.3 V across full temp/voltage range - rejects EMI-induced glitches
Low static current	ICC ≤ 20.0 μA (max) at VCC = 6.0 V and +125 °C - suitable for battery-backed or low-power monitoring

Applications

Waveform Shaping in Sensor Interfaces

Astable Multivibrator Oscillator

Use Scenario: Converting noisy analog output from a thermistor-based temperature sensor into clean square-wave logic for microcontroller capture.

IC Role / Device Role / Timing Role: Dual Schmitt inverter acts as edge cleaner and signal conditioner - first stage shapes sensor RC decay; second stage inverts and buffers.

Use Value: Eliminates false triggering caused by EMI on long sensor traces; enables reliable zero-crossing detection without software debouncing.

Use Scenario: Generating a stable 10 kHz clock signal using only one 74HC2G14GV,125, two resistors, and one capacitor in a feedback loop.

IC Role / Device Role / Timing Role: One inverter forms the gain stage; the other provides phase inversion - together they sustain oscillation via RC time constant.

Use Value: Provides low-cost, board-space-efficient clock generation without external crystal or dedicated oscillator IC.

Monostable Pulse Generation

Noise-Immune Pushbutton Debounce

Use Scenario: Creating a fixed 200 ms pulse upon detection of an external event (e.g., limit switch closure) in a PLC I/O module.

IC Role / Device Role / Timing Role: Configured as retriggerable monostable using RC network on input - output pulse width determined by R×C time constant.

Use Value: Delivers precise, jitter-free single-shot pulses immune to mechanical contact bounce or line transients.

Use Scenario: Debouncing front-panel pushbuttons in an industrial HMI where ESD and conducted noise cause spurious interrupts.

IC Role / Device Role / Timing Role: First inverter conditions button RC waveform; second inverter provides sharp-edged, glitch-free output to MCU GPIO.

Use Value: Achieves hardware-level debounce with <100 ns jitter - removes need for firmware polling or timer-based filtering.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
74HCT2G14GV,125	TTL-compatible inputs (VIH = 2.0 V min), narrower VCC range (4.5–5.5 V)	Better interoperability with legacy 5 V TTL logic families; less suitable for 3.3 V-only systems	Select when interfacing predominantly with 5 V TTL sources and strict VIH/VIL matching is required.
SN74LVC2G14DBVR	Lower VCC range (1.65–5.5 V), higher speed (tpd = 4.5 ns typ @ 3.3 V), no input clamps	Optimized for modern low-voltage FPGA/CPU I/O; lacks overvoltage protection without external diodes	Prefer for high-speed, low-voltage designs where input overvoltage is not expected and minimal propagation delay is critical.

Compared with 74HCT2G14GV,125, the 74HC2G14GV,125 offers broader supply flexibility and inherent overvoltage tolerance, while SN74LVC2G14DBVR delivers faster switching at lower voltages but requires external protection for VI > VCC scenarios.

FAQ

What is the maximum input voltage allowed when VCC = 3.3 V?

The 74HC2G14GV,125 features input clamp diodes that allow VI up to VCC + 0.5 V (i.e., 3.8 V) provided input current is limited to ±20 mA per JESD78. For sustained overvoltage, a series resistor must be used to keep IIK within rating - e.g., 1 kΩ limits current to 0.5 mA at 4.3 V.

Can both inverters be used independently with different supply voltages?

No - the device has a single VCC and GND pin shared by both inverters. All inputs and outputs operate referenced to this common supply; split-supply or dual-rail operation is not supported. Both channels must operate at the same VCC potential.

Is the 74HC2G14GV,125 suitable for driving a 50 pF capacitive load at 1 MHz?

Yes - with CL = 50 pF and VCC = 5.0 V, typical propagation delay is 18 ns and transition time is 17 ns, resulting in negligible distortion. Total dynamic power (PD = CPD × VCC² × fi × N) remains low at ~2.5 μW, well within the 250 mW package limit.

How does hysteresis change with temperature and supply voltage?

Hysteresis (VH) increases with VCC: 0.30 V (min) at 2.0 V, 1.40 V (max) at 6.0 V. Over temperature (−40 °C to +125 °C), VH variation is bounded - e.g., at VCC = 4.5 V, VH stays within 0.60–1.40 V. This monotonic behavior ensures consistent noise margin across operating conditions.
