Product details
Overview
74AHCT1G04GW,125 from Nexperia is a single-channel TTL-input inverter in TSSOP5 (SOT353-1) package, operating from 4.5 V to 5.5 V supply, featuring overvoltage-tolerant inputs up to 5.5 V, propagation delay of 3.4 ns (typ) at 5 V/15 pF, and guaranteed operation from –40 °C to +125 °C. It serves as a level-translating logic buffer in mixed-voltage digital subsystems such as industrial I/O interfaces and microcontroller peripheral conditioning.
For engineers reviewing the 74AHCT1G04GW,125 datasheet, 74AHCT1G04GW,125 pinout, 74AHCT1G04GW,125 application, or 74AHCT1G04GW,125 equivalent, key selection criteria include TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max), symmetrical output drive (±8 mA), latch-up immunity (>100 mA), and thermal-enhanced TSSOP5 packaging for high-density PCB layouts.
Technical Context
This device implements a single unbuffered CMOS inverter stage with TTL-level input switching thresholds, enabling direct interfacing with legacy 5 V TTL logic while maintaining low-power CMOS output characteristics. Its input structure supports overvoltage tolerance up to 5.5 V independent of VCC, allowing safe operation in voltage translation scenarios where input signals exceed the supply rail.
The internal design delivers balanced propagation delays (tPLH ≈ tPHL), symmetrical output impedance, and rail-to-rail output swing under load. It complies with JESD78 Class II Level A latch-up immunity and meets ANSI/ESDA/JEDEC JS-001 HBM (2000 V) and JS-002 CDM (1000 V) ESD standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - Ensures compatibility with standard 5 V TTL systems and rejects brownout below 4.5 V. |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - Matches TTL logic levels for seamless integration without level shifters. |
| Propagation Delay | 3.4 ns (typ) at VCC = 5.0 V, CL = 15 pF - Enables reliable operation in 100+ MHz clock domains with margin. |
| Output Drive | ±8 mA at VCC = 4.5 V - Sufficient to drive 10 LSTTL loads or 15 pF transmission lines without buffering. |
| Operating Temperature | –40 °C to +125 °C - Qualified for under-hood automotive modules, industrial PLCs, and outdoor power electronics. |
| Input Overvoltage Tolerance | 5.5 V absolute max on A pin - Allows safe connection to 5 V buses even when VCC is absent or ramping. |
| ESD Robustness | HBM > 2000 V, CDM > 1000 V - Reduces field failure risk during handling and board assembly. |
Pinout & Package
TSSOP5 (SOT353-1) package: plastic thin shrink small outline, 5-lead, body width 1.25 mm, 0.65 mm pitch, exposed pad not present, pin 1 index located lower-left corner below marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | n.c. | No internal connection - must be left floating or grounded per layout best practice; no electrical function. |
| 2 | A | Inverting data input - accepts TTL-level signals; overvoltage tolerant up to 5.5 V regardless of VCC. |
| 3 | GND | Digital ground reference - return path for all internal logic and output currents; requires low-impedance PCB plane. |
| 4 | Y | Inverted logic output - provides full-rail CMOS swing (0 V / VCC) with ±8 mA drive capability. |
| 5 | VCC | Positive supply - powers internal circuitry; bypass capacitor (100 nF) required within 5 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible input thresholds | Enables direct replacement of 74LS04 in legacy 5 V systems without redesigning input networks. |
| Overvoltage-tolerant input (5.5 V) | Permits hot-plug or bus-sharing configurations where signal sources may be powered before VCC stabilizes. |
| Symmetrical output impedance | Ensures matched rise/fall times (<10% skew) critical for timing-sensitive control signals like reset or enable lines. |
| –40 °C to +125 °C operation | Validates use in engine control units, motor drives, and industrial gateways without derating or thermal monitoring. |
| Low ICC (1.0 μA typ at 5.5 V) | Supports always-on subsystems (e.g., watchdog supervisors, wake-up logic) with sub-μA quiescent current budgets. |
Applications
| Industrial Sensor Interface | Microcontroller GPIO Conditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHC1G04GW,125 | CMOS input thresholds (VIH = 3.85 V @ 5.5 V), wider 2.0–5.5 V supply range | Better suited for mixed-supply systems with 3.3 V logic driving 5 V peripherals | Select when interfacing with modern low-voltage MCUs or when VCC may drop below 4.5 V. |
| SN74LVC1G04DBVR | 3.3 V only (1.65–5.5 V), lower typical tpd (3.0 ns @ 3.3 V/15 pF), different pinout (SOT-23-5) | Optimized for 3.3 V domains; not TTL-compatible - requires external pull-ups for 5 V bus use | Prefer for cost-sensitive 3.3 V-only designs where footprint and speed outweigh TTL compatibility needs. |

FAQ
Can 74AHCT1G04GW,125 operate with a 3.3 V supply?
No. The 74AHCT1G04GW,125 is specified only for 4.5 V to 5.5 V supply operation. At 3.3 V, input thresholds fall outside TTL specification (VIH minimum becomes undefined), and output drive degrades significantly. For 3.3 V systems, use the 74AHC1G04GW,125 variant instead, which supports 2.0–5.5 V with CMOS thresholds.
What is the maximum capacitive load this inverter can drive reliably?
The device is characterized up to 50 pF load capacitance, with propagation delay increasing from 3.4 ns (15 pF) to 4.9 ns (50 pF) at VCC = 5.0 V. For loads exceeding 50 pF, signal integrity degrades due to increased rise/fall times; add a series resistor or buffer stage if driving long traces or multiple fan-outs.
Is pin 1 of the TSSOP5 package internally connected?
No. Pin 1 is explicitly designated "n.c." (not connected) in the official Nexperia pin description table. It has no internal bond wire or silicon connection and must remain unconnected - neither tied to GND nor VCC - to avoid unintended coupling or leakage paths.
Does this part support hot-swap insertion into a live 5 V bus?
Yes - its overvoltage-tolerant inputs (rated to 5.5 V) and latch-up immunity (>100 mA per JESD78 Class II Level A) allow safe insertion into a powered 5 V backplane, provided VCC is applied before or concurrently with input signals. However, VCC must be stabilized before asserting valid logic levels to ensure proper internal biasing.
