Product details
Overview
74VHCT04AMTCX from ON Semiconductor is a hex inverter IC designed for 5V TTL-compatible digital logic interfacing, featuring 4.7ns typical propagation delay at 5V, ±25mA output drive capability, and dual-supply system compatibility (e.g., 3V-to-5V level translation). It operates across –40°C to +85°C and supports industrial control bus inversion.
For engineers reviewing the 74VHCT04AMTCX datasheet, pinout, applications, or equivalent options, key selection criteria include input threshold robustness (VIH = 2.0V, VIL = 0.8V), power-down protection on all I/O, low ICC (2µA max), and TSSOP-14 package suitability for high-density PCB layouts.
Technical Context
The 74VHCT04AMTCX implements six independent CMOS inverter gates using silicon-gate technology, with three-stage buffered output architecture that enhances noise immunity and output stability. Its input protection circuitry allows safe application of 0–7V signals regardless of VCC state, enabling hot-swap and battery-backup use cases.
It is fully compatible with 74HCT04 logic levels and timing, supports 5.0V ±0.5V operation, and meets JEDEC MO-153 TSSOP-14 mechanical standards. Input rise/fall time tolerance is specified up to 20ns/V, ensuring reliable operation with slow-edge signals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5V to 5.5V - Ensures stable operation under standard 5V rail tolerances in industrial systems. |
| tPD (Typ.) | 4.7ns at CL = 15pF - Enables high-speed signal inversion in clock distribution and data path buffering. |
| VOH / VOL | ≥3.94V / ≤0.36V at IOL = 8mA - Guarantees TTL-compatible output swing driving multiple loads. |
| VIH / VIL | 2.0V / 0.8V - Provides wide noise margin for reliable logic-level recognition in noisy environments. |
| ICC (Max) | 2µA at TA = 25°C - Supports ultra-low static power in always-on control subsystems. |
| Operating Temp | –40°C to +85°C - Qualified for extended-temperature industrial and automotive under-hood applications. |
| Input Protection | 0V to 7V input tolerance with VCC = 0V - Allows safe I/O biasing during power sequencing or brownout. |
Pinout & Package
74VHCT04AMTCX is housed in a 14-lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153 compliant, 4.4mm wide, with 0.65mm lead pitch and exposed pad not present. Pin 1 marked by notch or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Inverter Input (A1–A6) | CMOS inputs with power-down protection; accept 0–7V regardless of VCC state. |
| 2, 4, 6, 8, 10, 12 | Inverter Output (Y1–Y6) | Push-pull CMOS outputs capable of sourcing/sinking ±25mA; tolerate 0–7V when VCC = 0V. |
| 7 | GND | Ground reference for logic and power domains; must be low-impedance for noise immunity. |
| 14 | VCC | Positive supply (4.5–5.5V); powers internal logic and output stages; bypass capacitor required. |
Key Features
| Feature | Design Value |
|---|---|
| High-speed inversion | 4.7ns typical tPD enables use in 100+ MHz clock domain edge conditioning. |
| Input voltage tolerance | 0–7V input range with VCC = 0V supports hot-plug and mixed-voltage system interfacing. |
| Low quiescent current | 2µA max ICC allows integration into battery-backed real-time control modules without drain penalty. |
| TTL-compatible thresholds | 2.0V VIH / 0.8V VIL ensures interoperability with legacy 74HCT and 74LS families without level shifters. |
| Output noise suppression | VOLP ≤ 1.0V (CL = 50pF) reduces ground bounce and crosstalk in dense routing environments. |
Applications
| Industrial PLC I/O Expansion | Automotive Body Control Module |
|---|---|
Use Scenario: Inverting status signals from optocoupled inputs before feeding to microcontroller GPIOs. IC Role / Device Role / Timing Role: Signal polarity correction and noise-filtered logic-level translation between isolated 24V field side and 5V controller side. Use Value: Eliminates need for discrete inverters or software inversion; VIH/VIL margins prevent false triggering from EMI-induced transients. | Use Scenario: Driving LED indicators and relay drivers from MCU outputs requiring active-low enable logic. IC Role / Device Role / Timing Role: Hex buffer/inverter providing fan-out and polarity inversion for multiple body-control outputs. Use Value: ±25mA per output drives LEDs directly; -40°C to +85°C rating matches under-dash thermal requirements. |
| Legacy System Bus Interface | Test Equipment Signal Conditioning |
Use Scenario: Adapting 3.3V FPGA outputs to 5V TTL bus lines in retrofitted instrumentation backplanes. IC Role / Device Role / Timing Role: Level-shifting inverter enabling bidirectional compatibility between mixed-voltage subsystems. Use Value: Input protection allows safe connection even during power-up sequencing mismatches; 4.7ns delay preserves timing integrity. | Use Scenario: Cleaning up slow-rising test probe signals before digitization or triggering in benchtop analyzers. IC Role / Device Role / Timing Role: Schmitt-trigger-free waveform sharpening via fast CMOS inversion with controlled edge rates. Use Value: Low input capacitance (4pF typ.) minimizes loading on high-Z probe circuits; VOLP spec ensures clean trigger edges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74VHCT04MTCX | Same die, identical AC/DC specs; differs only in tape-and-reel packaging suffix (X present in both). | No functional difference; same TSSOP-14 footprint and performance. | Select 74VHCT04MTCX only if ordering documentation requires legacy Fairchild nomenclature without 'A' suffix. |
| SN74HCT04DR | TI part with identical pinout and logic function; tPD = 17ns (max), VIH/VIL same, but higher ICC (4µA max) and no 0–7V input tolerance. | Lacks input overvoltage protection; unsuitable for hot-swap or mixed-supply contexts where VCC may be unpowered. | Choose SN74HCT04DR only for cost-sensitive, single-rail 5V designs with no power sequencing risk. |
Compared with 74VHCT04MTCX and SN74HCT04DR, the 74VHCT04AMTCX uniquely combines sub-5ns speed, ultra-low ICC, and full 0–7V input survivability-making it optimal for robust, mixed-voltage industrial interfaces where reliability trumps marginal BOM cost savings.

FAQ
What is the maximum operating temperature range for the 74VHCT04AMTCX?
The 74VHCT04AMTCX is rated for operation from –40°C to +85°C, meeting industrial-grade thermal requirements. This range is validated per the Recommended Operating Conditions table in the official datasheet, and applies to all six inverter channels simultaneously under full load conditions at VCC = 5.5V.
Does the 74VHCT04AMTCX support 3.3V input signals while powered at 5V?
Yes, the 74VHCT04AMTCX accepts 3.3V logic inputs at 5V VCC because its VIH threshold is fixed at 2.0V (min), well below 3.3V. The device's input structure is CMOS-based with hysteresis-free TTL-compatible thresholds, making it safe and functional for 3.3V-to-5V translation without external resistors or level shifters.
Is the 74VHCT04AMTCX pin-compatible with the standard 74HCT04?
Yes, the 74VHCT04AMTCX is pin- and function-compatible with the 74HCT04, sharing identical pin numbering, logic behavior, and DC/AC specifications. Both devices use the same 14-pin TSSOP footprint, and the 74VHCT04AMTCX maintains backward compatibility while adding enhanced input protection and lower ICC.
What is the output drive strength of the 74VHCT04AMTCX?
The 74VHCT04AMTCX provides ±25mA DC output current per channel, verified under recommended operating conditions (VCC = 4.5–5.5V, TA = –40°C to +85°C). This allows direct driving of LEDs, small relays, or multiple 74-series inputs without external buffers, as confirmed in the Absolute Maximum Ratings and DC Electrical Characteristics tables.
Can unused inputs on the 74VHCT04AMTCX be left floating?
No, unused inputs on the 74VHCT04AMTCX must be tied HIGH or LOW - floating inputs are prohibited. The datasheet explicitly states in Note 4 of the Recommended Operating Conditions table that unused inputs may not float, as this can cause increased ICC, oscillation, or excessive power dissipation due to undefined input stage biasing.
