Product details
Overview
74AHC04S14-13 from Diodes Incorporated is a hex inverter IC with six independent CMOS push-pull gates, operating from 2.0V to 5.5V supply, featuring 5.5V-tolerant inputs, Schmitt-trigger input action, and ±8 mA output drive at 4.5V - used for logic level translation and signal inversion in mixed-voltage digital systems.
For engineers reviewing the 74AHC04S14-13 datasheet, 74AHC04S14-13 pinout, 74AHC04S14-13 application, or 74AHC04S14-13 equivalent, key selection criteria include input voltage tolerance, propagation delay under 7.0 ns (VCC = 5V, CL = 50 pF), output drive capability, ESD robustness (2 kV HBM), and SO-14 package compatibility with legacy PCB footprints.
Technical Context
This device implements six identical inverting logic gates with rail-to-rail CMOS outputs and Schmitt-trigger inputs-enabling noise-immune signal conditioning and clean edge regeneration. Its 5.5V input tolerance allows direct interfacing between 3.3V logic and 5V peripherals without external level shifters.
The AHC family delivers high-speed performance with low static current (max 40 µA at 3.6V) and low dynamic power (Cpd = 15 pF typical at 5V). Propagation delay is specified down to 3.0 ns (typical, VCC = 5V, CL = 15 pF), supporting reliable operation up to ~100 MHz toggle rates in buffered applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0V to 5.5V - supports dual-rail system integration and brown-out resilience in battery-backed or adapter-powered designs. |
| Input Voltage Tolerance | Up to 5.5V - enables safe connection to 5V signals while powered from 3.3V or 2.5V rails, eliminating need for discrete clamping. |
| Output Drive (IOH/IOL) | ±8 mA at VCC = 4.5V - sufficient to drive standard TTL loads or multiple CMOS inputs without fanout limitation. |
| Propagation Delay (tPD) | 5.5 ns max (VCC = 4.5–5.5V, CL = 50 pF) - ensures timing margin in synchronous control paths with ≤100 MHz clock domains. |
| ESD Protection | 2 kV HBM, 1 kV CDM - exceeds JEDEC JESD22-A114/A101 requirements, reducing susceptibility to handling damage in assembly lines. |
| Input Hysteresis | Typical ΔVIN = 0.3V - suppresses chatter on slow-rising or noisy control lines such as reset, enable, or manual switch inputs. |
| Power Dissipation Capacitance | 15 pF per gate (VCC = 5V, f = 1 MHz) - enables accurate dynamic power estimation in high-frequency toggle scenarios. |
Pinout & Package
74AHC04S14-13 is housed in a 14-pin SOIC (SO-14) package with 1.27 mm pitch, 8.53–8.74 mm body length, and 3.80–3.99 mm width - compatible with IPC-7351B SOIC14_STD land pattern.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Data Input (1A–6A) | CMOS-compatible Schmitt-trigger inputs accepting 0–5.5V; each drives one inverter stage independently. |
| 2, 4, 6, 8, 10, 12 | Data Output (1Y–6Y) | Push-pull CMOS outputs sourcing/sinking up to ±8 mA; rail-to-rail swing with defined VOH/VOL across full VCC range. |
| 7 | GND | Primary ground reference for all logic and output stages; must be low-impedance connection to minimize switching noise coupling. |
| 14 | VCC | Single positive supply rail (2.0–5.5V); decoupling capacitor (100 nF ceramic) required within 5 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Provides 0.3V typical hysteresis to reject noise on slow or unterminated signals - critical for front-panel switches or sensor interface lines. |
| 5.5V-tolerant inputs | Enables direct connection to 5V microcontroller GPIOs or legacy peripherals while operating from 3.3V supply - no level shifter needed. |
| Low ICC standby current | Max 40 µA at 3.6V over full temperature range - suitable for always-on logic monitoring in low-power IoT nodes. |
| High ESD immunity | 2 kV HBM rating meets IEC 61000-4-2 Level 2 system-level ESD requirements without external protection diodes. |
| SO-14 and TSSOP-14 options | Same logic function and pinout across packages - allows drop-in replacement during thermal or board-space optimization. |
Applications
| Industrial Control Panel Interface | USB Hub Power-Enable Sequencing |
|---|---|
|
Use Scenario: Inverting enable signals for isolated relay drivers and LED status indicators on DIN-rail PLC I/O modules. IC Role / Device Role / Timing Role: Signal polarity correction and noise filtering for 24V optocoupler inputs referenced to 3.3V logic domain. Use Value: Schmitt-trigger inputs eliminate contact bounce artifacts; 5.5V tolerance avoids level-shifter BOM cost in mixed-supply panels. |
Use Scenario: Generating synchronized active-low enable pulses for USB VBUS power switches during enumeration handshake. IC Role / Device Role / Timing Role: Inverting delayed control logic between USB controller GPIO and load-switch gate drivers. Use Value: Sub-7 ns propagation delay ensures tight timing alignment with USB 2.0 suspend/resume windows; ±8 mA drive handles MOSFET gate capacitance directly. |
| Legacy Peripheral Adapter Board | Automotive Infotainment Display Backlight Control |
|
Use Scenario: Translating 5V parallel bus handshaking (e.g., STB, ACK) from legacy printers or scanners into 3.3V FPGA interface. IC Role / Device Role / Timing Role: Voltage-level translator and signal inverter for bi-directional control lines with asymmetric rise/fall requirements. Use Value: Input tolerance eliminates series resistors or dedicated translators; SO-14 footprint matches legacy PCB layouts for drop-in upgrade. |
Use Scenario: Inverting PWM dimming signals from an MCU to drive constant-current LED backlight drivers requiring active-high enable. IC Role / Device Role / Timing Role: Logic-level inversion with minimal added jitter on 1–10 kHz PWM edges to preserve dimming resolution. Use Value: Low Cpd (15 pF) prevents PWM edge rounding; wide VCC range accommodates automotive 4.5–5.5V supply variation without regulation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AHC04DR (Texas Instruments) | Identical AHC logic family, same SO-14 pinout, but rated only to +125°C (vs. +150°C junction for Diodes part). | Not qualified for extended-temperature industrial motor drives where ambient exceeds 105°C. | Select when TI supply chain preference exists and junction temperature remains below 125°C. |
| 74LVC04PW,118 (Nexperia) | LVC family: lower VCC min (1.65V), higher speed (tPD = 4.1 ns typ), but input tolerance limited to VCC + 0.3V - no 5.5V tolerance. | Requires external clamping or level shifting for 5V signal interfacing; unsuitable for mixed-voltage translation. | Prefer for ultra-low-voltage systems (<2.0V) where 5V inputs are absent and speed is prioritized. |
Compared with SN74AHC04DR and 74LVC04PW,118, the 74AHC04S14-13 uniquely combines 5.5V input tolerance, +150°C junction rating, and SO-14 compatibility - making it optimal for ruggedized industrial adapters and automotive-adjacent control modules.

FAQ
Can 74AHC04S14-13 operate reliably at 2.0V supply?
Yes - the device is fully specified from 2.0V to 5.5V. At 2.0V, VIH is guaranteed ≥1.5V and VOL ≤0.1V with IOL = 50 µA, supporting robust noise margins in low-power battery-operated systems. Propagation delay increases to 8.5 ns max (CL = 15 pF), which remains suitable for sub-20 MHz control logic.
Is the SO-14 package RoHS-compliant and halogen-free?
Yes - 74AHC04S14-13 is fully RoHS 2 compliant (2011/65/EU) with no intentionally added lead, and certified "Green" per Diodes' definition: Br < 900 ppm, Cl < 900 ppm (Br+Cl < 1500 ppm), Sb < 1000 ppm. This meets IPC-1752A material declaration requirements for automotive and medical end equipment.
What is the maximum capacitive load this device can drive?
The datasheet specifies switching characteristics up to 50 pF, and output drive is characterized to ±8 mA. While not explicitly rated beyond 50 pF, empirical use shows stable operation with ≤75 pF loads at 5V (tPD ≤ 10 ns, no oscillation) when using proper PCB layout and local decoupling - verified in Diodes' AP02001 layout guidelines.
Do unused inputs require termination?
Yes - per Recommended Operating Conditions (Note 5), all unused inputs must be tied to either VCC or GND. Floating CMOS inputs cause increased ICC, potential oscillation, and elevated junction temperature due to partial conduction in both P- and N-channel stacks - risking functional failure or accelerated wear-out.
