Product details
Overview
74HCT1G04GV,125 from Nexperia is a single TTL-compatible CMOS inverter in SC-74A (SOT753) package with 5-pin configuration, operating from 4.5 V to 5.5 V supply, delivering symmetrical output impedance (±2.0 mA drive), propagation delay of 10 ns (typ.) at 4.5 V/50 pF, and specified for -40 °C to +125 °C industrial temperature range - used for signal inversion in level-shifting interfaces between legacy TTL logic and modern low-voltage CMOS systems.
For engineers reviewing the 74HCT1G04GV,125 datasheet, 74HCT1G04GV,125 pinout, 74HCT1G04GV,125 application, or 74HCT1G04GV,125 equivalent, key selection considerations include TTL-level input compatibility, 5-pin SC-74A footprint constraints, guaranteed operation up to +125 °C, and static/dynamic performance under 4.5–5.5 V supply with 50 pF load.
Technical Context
This device implements a single unbuffered inverter gate with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), enabling direct interfacing with 5 V TTL outputs without level translation. Its CMOS output stage provides rail-to-rail swing and symmetrical sourcing/sinking capability.
Designed for high-noise-immunity digital signal conditioning, it features input clamp diodes allowing safe interface to voltages exceeding VCC when current-limited, and meets JESD7A (2.0–6.0 V) and JEDEC JESD8C standards for 2.7–3.6 V operation compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL and mixed-voltage logic domains. |
| Propagation Delay | 10 ns (typ.) at VCC = 4.5 V, CL = 50 pF - enables reliable timing in sub-25 MHz digital control paths. |
| Output Drive | ±2.0 mA at VCC = 4.5 V - sufficient to drive one 74-series TTL input or multiple CMOS loads with margin. |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - matches legacy TTL logic levels for seamless integration. |
| Operating Temperature | -40 °C to +125 °C - supports under-hood automotive modules, industrial PLC I/O, and high-ambient embedded controllers. |
| Power Dissipation | 250 mW max at Tamb ≤ 85 °C (derates 3.8 mW/K above 85 °C) - defines thermal limits for PCB layout in dense SMT assemblies. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - reduces handling sensitivity during manual assembly and board rework. |
Pinout & Package
SC-74A (SOT753) plastic surface-mounted package: 5-lead, 1.3 mm × 1.7 mm body, 0.65 mm pitch, pin 1 index located below marking code in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | n.c. | No internal connection - must remain unconnected; no routing or soldering required. |
| 2 | A | Inverter input - accepts TTL-level signals; clamp diodes permit safe overvoltage tolerance with external current limiting. |
| 3 | GND | Digital ground reference - requires low-inductance connection to system ground plane for noise immunity. |
| 4 | Y | Inverted output - delivers full-rail CMOS swing; capable of driving capacitive loads up to 50 pF within spec. |
| 5 | VCC | Positive supply - must be decoupled locally with ≥100 nF ceramic capacitor near pin 5 for stable switching. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | VIH ≥ 2.0 V and VIL ≤ 0.8 V at 4.5–5.5 V - eliminates need for external level shifters when interfacing with 74LS/74ALS families. |
| Symmetrical output impedance | Matched rise/fall times and ±2.0 mA drive - ensures clean square-wave output with minimal duty-cycle distortion. |
| High noise immunity | Typical noise margin > 0.9 V at VCC = 5 V - suppresses false triggering in electrically noisy industrial environments. |
| Wide temperature operation | Guaranteed function from -40 °C to +125 °C - validated for extended-life deployment in automotive engine control units and motor drives. |
| Low static power | ICC ≤ 20 μA max at VCC = 5.5 V - enables use in always-on subsystems without significant quiescent current penalty. |
Applications
| Industrial Sensor Interface | Legacy System Glue Logic |

Equivalent & Alternatives
The following parts are listed as comparable options for similar inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT1G04GW,125 | TSSOP5 (SOT353) package, 1.25 mm body width, 0.65 mm pitch - identical electrical specs but different land pattern. | Preferred where board space allows larger footprint or thermal derating above 74 °C is needed (3.3 mW/K vs 3.8 mW/K). | Select when higher thermal mass or existing TSSOP5 layout reuse is prioritized over minimal area. |
| SN74LVC1G04DBVR | CMOS-input variant (not TTL-compatible); VIH = 1.7 V min at VCC = 3.3 V; operates down to 1.65 V supply. | Used in 3.3 V-only systems; cannot directly replace 74HCT1G04GV,125 in 5 V TTL interface scenarios. | Choose only for new 3.3 V designs requiring lower supply flexibility - not drop-in compatible. |
Compared with 74HCT1G04GW,125, this SC-74A variant saves 0.15 mm in width and offers tighter thermal derating above 85 °C; versus SN74LVC1G04DBVR, it provides mandatory TTL-level recognition essential for legacy interoperability but lacks sub-3 V operation.

FAQ
Is 74HCT1G04GV,125 pin-compatible with 74HC1G04GV,125?
Yes - both share identical SC-74A (SOT753) pinout and mechanical footprint. However, 74HCT1G04GV,125 uses TTL-level inputs (VIH ≥ 2.0 V), while 74HC1G04GV,125 requires CMOS-level inputs (VIH ≥ 3.15 V at VCC = 4.5 V). Swapping them may cause logic misreads in 5 V systems without proper level validation.
Can 74HCT1G04GV,125 operate at 3.3 V supply?
No - its recommended operating range is strictly 4.5 V to 5.5 V. At 3.3 V, input thresholds fall outside specification (VIH min drops to 1.5 V, violating TTL compatibility), and propagation delay increases significantly beyond datasheet guarantees. Use 74LVC1G04 for 3.3 V operation.
What is the maximum capacitive load this inverter can drive reliably?
It is characterized for 50 pF load per the datasheet (tpd = 10 ns typ. at VCC = 4.5 V). Driving >50 pF increases propagation delay nonlinearly and may cause overshoot/ringing; for >100 pF loads, add series termination or consider buffered inverters like 74HCT1G14.
Does 74HCT1G04GV,125 require external pull-up or pull-down resistors on unused pins?
Pin 1 is n.c. (no internal connection) and must remain unconnected - no resistor needed. Inputs must never float; if A (pin 2) is unused, tie it to GND or VCC via ≤10 kΩ resistor to prevent metastability and excess ICC. Output Y (pin 4) may be left open only if not connected to any load.
