Product details
Overview
74VHCT04AM from ON Semiconductor is a hex inverter IC designed for 5V TTL-compatible digital logic interfacing, featuring propagation delay of 4.7ns (typ), input thresholds of VIH = 2.0V and VIL = 0.8V, and quiescent ICC ≤ 2µA at TA = 25°C. It enables level-shifting between 3V and 5V systems and supports battery-backup dual-supply operation.
For engineers reviewing the 74VHCT04AM datasheet, pinout, applications, or equivalent options, key selection criteria include its 14-lead SOIC package, 4.5–5.5V supply range, ±25mA output drive, power-down protection on all I/O, and compatibility with 74HCT04 logic families.
Technical Context
The 74VHCT04AM implements six independent CMOS inverter gates using silicon-gate technology, achieving bipolar-Schottky TTL speed while retaining CMOS low-power characteristics. Its three-stage buffered output architecture ensures high noise immunity and stable switching waveforms under capacitive loads up to 50pF.
Input protection circuitry allows safe application of 0–7V signals regardless of VCC state-including VCC = 0V-enabling hot-plug and mixed-voltage system interoperability. Outputs are specified for VOL ≤ 0.44V at IOL = 8mA and VOH ≥ 3.94V at IOH = –8mA under 4.5V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5V to 5.5V - Ensures robust operation across industrial-grade 5V rails with ±10% tolerance. |
| Propagation Delay | 4.7ns (typ) at CL = 15pF - Supports >100MHz toggle rates in clean signal paths. |
| Input Thresholds | VIH = 2.0V, VIL = 0.8V - Guarantees reliable recognition of TTL-level inputs at 5V VCC. |
| Output Drive | ±25mA DC - Sufficient to directly drive multiple 74-series inputs or small LEDs without buffering. |
| Quiescent Current | 2µA max at 25°C - Enables ultra-low static power in always-on control logic or standby circuits. |
| Operating Temp | –40°C to +85°C - Qualified for industrial ambient environments without derating. |
| Input Protection | 0V to 7V tolerant with VCC = 0V - Permits safe I/O exposure during power sequencing or brownout conditions. |
Pinout & Package
74VHCT04AM is housed in a 14-lead Small Outline Integrated Circuit (SOIC) package per JEDEC MS-012, 0.150" narrow body, with standard 1.27mm lead pitch and RoHS-compliant lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Inverter Input (A1–A6) | CMOS-compatible digital inputs accepting 0–5.5V; internally protected against overvoltage and floating states. |
| 2, 4, 6, 8, 10, 12 | Inverter Output (Y1–Y6) | Push-pull CMOS outputs capable of sourcing/sinking ±25mA; include power-down protection when VCC = 0V. |
| 7 | GND | Logic ground reference; must be connected to system common return path for noise immunity and correct threshold operation. |
| 14 | VCC | Positive supply rail (4.5–5.5V); decoupling capacitor (0.1µF ceramic) required within 10mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| High-speed inversion | 4.7ns typical propagation delay enables timing-critical clock buffering and signal conditioning in 5V systems. |
| TTL-input compatible thresholds | VIH = 2.0V / VIL = 0.8V ensures seamless integration with legacy 74LS/74ALS and microcontroller GPIOs. |
| Power-down I/O protection | Inputs and outputs remain undamaged and non-interfering when VCC = 0V, supporting hot-swap and backup-power architectures. |
| Low dynamic noise | VOLP ≤ 1.0V (max) at CL = 50pF reduces crosstalk and ground bounce in dense PCB layouts. |
| Pin/function compatibility | Direct drop-in replacement for 74HCT04 in existing designs, preserving layout, BOM, and firmware. |
Applications
| Industrial Control Logic | Microcontroller Interface Buffering |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT04D | Same logic function and 5V supply range, but specified for slightly higher ICC (4µA max) and slower tPD (17ns typ at 50pF). | Limited to lower-speed control logic where propagation delay >10ns is acceptable. | Select when cost sensitivity outweighs speed requirement and legacy footprint compatibility is critical. |
| SN74LVC04APW | 3.3V-only operation (1.65–3.6V), smaller TSSOP-14 package, and faster tPD (4.1ns typ), but no 5V-tolerant inputs. | Restricted to pure 3.3V systems; incompatible with 5V signal sources without external clamping. | Choose for new 3.3V designs prioritizing size, speed, and lower VCC, not for 5V or mixed-voltage use. |
Compared with 74HCT04D and SN74LVC04APW, the 74VHCT04AM uniquely balances 5V TTL compatibility, sub-5ns speed, ultra-low quiescent current, and full 0–7V input tolerance-making it optimal for industrial 5V systems requiring robustness, timing precision, and mixed-supply resilience.

FAQ
What is the maximum operating supply voltage for the 74VHCT04AM?
The 74VHCT04AM supports a recommended supply voltage range of 4.5V to 5.5V. Its absolute maximum VCC rating is +7.0V, but operation above 5.5V is not guaranteed and may compromise parametric performance or reliability. For sustained 5V system use, 4.5–5.5V ensures compliance with all AC/DC specifications in the datasheet.
Does the 74VHCT04AM support mixed-voltage interfacing between 3V and 5V systems?
Yes, the 74VHCT04AM supports mixed-voltage interfacing. Its inputs tolerate 0–7V regardless of VCC state, enabling direct connection to 3.3V logic outputs even when powered from 5V. Outputs swing rail-to-rail (0V to VCC), making them compatible with both 3.3V and 5V receivers when VCC = 5V and proper input thresholds are met.
Is the 74VHCT04AM pin-compatible with the standard 74HCT04?
Yes, the 74VHCT04AM is pin- and function-compatible with the 74HCT04. Both devices share identical 14-pin SOIC packaging, identical pin assignments (inputs on odd pins 1/3/5/9/11/13, outputs on even pins 2/4/6/8/10/12), and identical truth table behavior. This allows direct substitution without PCB or schematic changes.
What is the purpose of power-down protection in the 74VHCT04AM?
Power-down protection in the 74VHCT04AM prevents damage and unintended behavior when VCC = 0V. Inputs and outputs remain electrically isolated and non-destructive across –0.5V to 7.0V, allowing safe signal routing during power sequencing, battery switchover, or partial system shutdown-critical in backup-power and hot-plug applications.
Can the 74VHCT04AM drive capacitive loads up to 50pF while maintaining its specified propagation delay?
Yes, the 74VHCT04AM's AC Electrical Characteristics explicitly specify tPHL/tPLH = 5.5ns (typ) at CL = 50pF and VCC = 5.0V ± 0.5V. This confirms guaranteed timing performance under realistic PCB trace and input capacitance loading, supporting reliable operation in bus-driven or multi-load configurations without added delay uncertainty.
