Product details
Overview
74VHCT04AMTC 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 2µA maximum quiescent ICC at 25°C. It enables level-shifting between 3V and 5V systems and supports battery-backup dual-supply operation.
For engineers reviewing the 74VHCT04AMTC datasheet, pinout, applications, or equivalent options, key selection criteria include its TSSOP-14 package, 4.5–5.5V operating range, input overvoltage tolerance up to 7V, power-down protection, and compatibility with 74HCT04 logic families.
Technical Context
The 74VHCT04AMTC implements six independent CMOS inverter gates using silicon-gate technology, achieving bipolar-Schottky TTL speed while retaining CMOS power efficiency. Its three-stage buffered output architecture ensures high noise immunity (VIH = 2.0V, VIL = 0.8V) and stable switching under capacitive loads up to 50pF.
Input and output protection circuits allow safe operation with VCC = 0V and tolerate –0.5V to +7.0V on all pins regardless of supply state. This enables hot-swap capability and robust interfacing across mismatched voltage domains including 3V-to-5V translation and backup-power scenarios.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5V to 5.5V - Ensures compatibility with standard 5V TTL and mixed-voltage systems. |
| Propagation Delay | 4.7ns (typ.) at VCC = 5.0V, CL = 15pF - Enables high-speed signal inversion in timing-critical paths. |
| Output Drive | ±25mA - Supports direct driving of multiple TTL inputs or moderate capacitive loads. |
| Quiescent ICC | 2µA (max.) at 25°C - Delivers ultra-low static power for battery-sensitive applications. |
| Input Voltage Range | –0.5V to +7.0V - Permits safe operation during power sequencing and voltage transients. |
| Operating Temperature | –40°C to +85°C - Qualified for industrial ambient environments without derating. |

Pinout & Package
74VHCT04AMTC is housed in a 14-lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm wide, with 0.65mm lead pitch and gull-wing terminations. The package is lead-free per JEDEC J-STD-020B.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Inverter Input (A1–A6) | Digital logic inputs accepting TTL-level signals; internally protected to ±20mA diode current. |
| 2, 4, 6, 8, 10, 12 | Inverter Output (Y1–Y6) | CMOS push-pull outputs capable of sourcing/sinking ±25mA; support power-down isolation when VCC = 0V. |
| 7 | GND | Ground reference for all logic and I/O; must be connected to system common ground plane. |
| 14 | VCC | Positive supply rail (4.5–5.5V); decoupling capacitor (0.1µF) required near pin for noise suppression. |
Key Features
| Feature | Design Value |
|---|---|
| High-speed inversion | 4.7ns typical tPD enables use in clock distribution, data path buffering, and fast control logic. |
| Input overvoltage tolerance | Withstands –0.5V to +7.0V on inputs regardless of VCC state - eliminates need for external clamping in mixed-rail systems. |
| Power-down protection | Inputs and outputs remain high-impedance and non-destructive when VCC = 0V - supports hot-plug and backup-power modes. |
| Low-noise output | VOLP ≤ 1.0V (max.) at CL = 50pF - reduces switching-induced ground bounce in dense PCB layouts. |
| TTL-compatible thresholds | VIH = 2.0V / VIL = 0.8V - ensures reliable recognition of legacy 5V TTL outputs without level shifters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HCT04DR | SOIC-14 package (wider 3.9mm body); identical electrical specs and pinout. | Preferred where board space allows larger SOIC footprint and hand-soldering is used. | Select SN74HCT04DR for cost-sensitive industrial designs requiring SOIC manufacturability and broader distributor stock. |
| 74VHC04MTCX | VHC family: wider 2–5.5V supply range; lower 3.5ns tPD but no input overvoltage tolerance beyond VCC+0.5V. | Suitable for single-supply 3.3V systems but not for 3V/5V interfacing or hot-swap scenarios. | Choose 74VHC04MTCX only when operating strictly within 3.3V domain and highest speed is prioritized over robustness. |
Compared with SN74HCT04DR and 74VHC04MTCX, the 74VHCT04AMTC uniquely combines 5V TTL compatibility, 7V input tolerance, and TSSOP-14 compactness-making it optimal for space-constrained, mixed-voltage, or hot-swap-capable designs where reliability under supply mismatch is critical.

FAQ
What is the maximum input voltage the 74VHCT04AMTC can safely withstand?
The 74VHCT04AMTC supports DC input voltages from –0.5V to +7.0V regardless of VCC state, enabling safe operation during power sequencing, hot-swap events, and transient overvoltage conditions. This specification is validated per Absolute Maximum Ratings and confirmed in the Fairchild/ON Semiconductor datasheet Rev. 1.4.0. The 74VHCT04AMTC achieves this via integrated input protection diodes rated for ±20mA continuous current.
Does the 74VHCT04AMTC support operation with VCC = 0V?
Yes, the 74VHCT04AMTC features power-down protection that maintains input and output integrity even when VCC = 0V. Inputs tolerate –0.5V to +7.0V, and outputs enter high-impedance state without latch-up or damage. This behavior is explicitly guaranteed in the datasheet's Recommended Operating Conditions and Absolute Maximum Ratings sections. The 74VHCT04AMTC is therefore suitable for battery-backup systems and hot-plug modules.
Is the 74VHCT04AMTC pin-compatible with the standard 74HCT04?
Yes, the 74VHCT04AMTC is pin- and function-compatible with the 74HCT04, sharing identical pin assignments, truth table, and logic behavior. Both devices use the same 14-pin configuration with six independent inverters, GND on pin 7, and VCC on pin 14. This compatibility is stated in the "General Description" and "Features" sections of the 74VHCT04A datasheet Rev. 1.4.0. The 74VHCT04AMTC can serve as a direct replacement in existing 74HCT04 designs.
What is the typical propagation delay of the 74VHCT04AMTC at 5V supply?
The 74VHCT04AMTC exhibits a typical propagation delay (tPHL/tPLH) of 4.7ns at VCC = 5.0V ±0.5V and CL = 15pF, as measured per AC Electrical Characteristics in the official datasheet. This value is confirmed across temperature (–40°C to +85°C) with a maximum of 7.5ns under worst-case conditions. The 74VHCT04AMTC delivers TTL-equivalent speed while maintaining CMOS power efficiency, making it suitable for high-frequency digital control paths.
What package type does the 74VHCT04AMTC use, and what are its key mechanical dimensions?
The 74VHCT04AMTC uses a 14-lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, variation AB, with a 4.4mm body width and 0.65mm lead pitch. Key dimensions include overall length 5.0mm, height 1.2mm max, and seating plane coplanarity ≤0.10mm. This package is lead-free and complies with JEDEC J-STD-020B reflow profiles. The 74VHCT04AMTC's compact TSSOP footprint supports high-density PCB layouts while maintaining manufacturability in automated SMT lines.
