Product details
Overview
MC74HC04ADTEL from onsemi is a high-performance silicon-gate CMOS hex inverter IC containing six independent three-stage inverters in a 14-lead TSSOP package. It operates from 2 V to 6 V, delivers ±25 mA output drive per pin, exhibits 13 ns propagation delay at 6 V (CL = 50 pF), and supports industrial temperature range (–55 °C to +125 °C). It is used for logic-level translation, signal conditioning, and clock buffering in embedded control systems.
For engineers reviewing the MC74HC04ADTEL datasheet, pinout, applications, or equivalent options, this page provides verified pin mapping, JEDEC-compliant voltage thresholds, LSTTL-load drive capability, noise immunity data, and validated alternative options for logic inversion in mixed-voltage digital systems.
Technical Context
The MC74HC04ADTEL implements six identical CMOS inverters using three-stage buffered architecture to minimize input capacitance and improve transient response. Each inverter features rail-to-rail output swing and guaranteed VIH/VIL thresholds across full supply and temperature range.
It complies with JEDEC Standard No. 7A, supports direct interfacing to CMOS, NMOS, and TTL families (with pull-up resistors for LSTTL), and maintains low quiescent ICC (≤40 µA at 6 V, +125 °C) due to silicon-gate process optimization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Propagation Delay (tPLH/tPHL) | 13 ns max at VCC = 6 V, CL = 50 pF - Supports >30 MHz toggle rates in clean signal paths. |
| Output Drive | ±25 mA per pin - Drives up to 10 LSTTL loads directly; sufficient for fanout into multiple downstream gates. |
| Input Leakage Current | ±1.0 µA max at +125 °C - Ensures stable logic states with high-impedance inputs; no external pull-ups required for unused pins when tied to rail. |
| Operating Temperature | –55 °C to +125 °C - Qualified for under-hood automotive, industrial motor control, and outdoor equipment applications. |
| Input Capacitance (Cin) | 10 pF max - Minimizes loading on preceding stage; critical for high-speed bus termination and oscillator stability. |
| Power Dissipation Cap. (CPD) | 20 pF per inverter - Used to calculate dynamic power: PD = CPD × VCC² × f + ICC × VCC; enables accurate thermal budgeting. |
Pinout & Package
TSSOP–14 package (Case 948G–01), 5.0 mm × 4.4 mm footprint, 0.65 mm lead pitch, exposed pad optional, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A1 (Input of Inverter 1) | Dedicated CMOS-compatible input; VIH ≥ 4.2 V @ VCC = 6 V ensures robust noise margin vs. TTL. |
| 2 | Y1 (Output of Inverter 1) | Rail-to-rail CMOS output; VOL ≤ 0.40 V @ IOL = 5.2 mA supports reliable low-state detection. |
| 3 | A2 (Input of Inverter 2) | Electrically isolated from other inputs; allows independent signal inversion without crosstalk. |
| 4 | Y2 (Output of Inverter 2) | Matched propagation delay (tPLH/tPHL) to Y1; enables synchronous dual-channel inversion. |
| 5 | A3 (Input of Inverter 3) | Compatible with standard CMOS outputs; no pull-up needed when driven by HC/HCT family. |
| 6 | Y3 (Output of Inverter 3) | Capable of sinking 5.2 mA while maintaining VOL ≤ 0.40 V - suitable for LED anode drive with current-limiting resistor. |
| 7 | GND | Ground reference for all inputs/outputs; must be low-inductance connection to minimize ground bounce. |
| 8 | A4 (Input of Inverter 4) | Accepts DC input voltages from 0 V to VCC; tolerant of slow edges (tr/tf ≤ 1000 ns @ 2 V). |
| 9 | Y4 (Output of Inverter 4) | Output transition time tTLH/tTHL ≤ 13 ns @ 6 V - preserves edge integrity in clock distribution networks. |
| 10 | A5 (Input of Inverter 5) | High noise immunity (typical 40% VCC) - rejects EMI in noisy industrial environments. |
| 11 | Y5 (Output of Inverter 5) | Guaranteed VOH ≥ 5.48 V @ VCC = 6 V, IOL = 5.2 mA - ensures valid high-level signaling to 5 V CMOS loads. |
| 12 | A6 (Input of Inverter 6) | Pin-compatible with LS04 and MC14069 - enables drop-in replacement in legacy designs. |
| 13 | Y6 (Output of Inverter 6) | Independent output; can be left open if unused - no internal pull-up/down required. |
| 14 | VCC | Supply rail; requires local 100 nF ceramic decoupling within 5 mm of pin to suppress switching noise. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC04DR | TI part; identical AC/DC specs but different thermal resistance (θJA = 173 °C/W vs. onsemi's 190 °C/W); same TSSOP-14 footprint. | Valid for commercial-grade (0 °C to +70 °C) designs only; not qualified for extended temperature range. | Select when cost sensitivity outweighs extended temp requirement and TI supply chain preference applies. |
| 74HC04PW,118 | Nexperia part; matches VCC range and drive strength, but specifies tPLH/tPHL = 15 ns @ 6 V (vs. 13 ns), and Cin = 3.5 pF (lower). | Better high-frequency performance due to lower input capacitance; slightly higher propagation delay acceptable in non-critical paths. | Prefer for ultra-low-capacitance interfaces (e.g., RF control lines) where 2 ns delay penalty is acceptable. |
Compared with SN74HC04DR and 74HC04PW,118, the MC74HC04ADTEL offers superior high-temperature operation (–55 °C to +125 °C), tighter propagation delay guarantee (13 ns), and documented JEDEC 7A compliance - making it the preferred choice for automotive and industrial control applications requiring long-term reliability under thermal stress.

FAQ
What is the maximum operating frequency supported by the MC74HC04ADTEL?
The MC74HC04ADTEL does not specify a maximum operating frequency in its datasheet, as it is a combinational logic device. Its usable toggle rate depends on propagation delay and load conditions. With 13 ns max tPLH/tPHL at VCC = 6 V and CL = 50 pF, the MC74HC04ADTEL supports reliable operation up to approximately 30 MHz in well-designed PCB layouts with controlled impedance and proper decoupling.
Can the MC74HC04ADTEL drive LEDs directly?
Yes, the MC74HC04ADTEL can drive LEDs directly when configured in active-low mode (LED anode to VCC, cathode to output). At VCC = 5 V and IOL = 5.2 mA, VOL remains ≤ 0.40 V, providing ~4.6 V forward bias. A series current-limiting resistor (e.g., 330 Ω for ~13 mA) must be used to stay within the ±25 mA absolute maximum output rating and avoid exceeding power dissipation limits.
Is the MC74HC04ADTEL pin-compatible with older TTL inverters?
Yes, the MC74HC04ADTEL is explicitly stated to be identical in pinout to the 74LS04 and MC14069. All six inverter inputs and outputs, plus VCC and GND, occupy the same positions in the TSSOP-14 package as those devices - enabling direct PCB replacement in legacy designs when operated within the 2–6 V supply range.
Does the MC74HC04ADTEL require external pull-up resistors on inputs?
No, external pull-up resistors are not required on MC74HC04ADTEL inputs unless interfacing with LSTTL outputs. Its inputs are fully compatible with standard CMOS outputs across the entire 2–6 V supply range. Pull-ups are only needed when driving from open-collector or high-impedance LSTTL sources to ensure valid logic-high levels above VIH threshold.
What is the recommended PCB layout practice for the MC74HC04ADTEL's power pins?
Place a 100 nF X7R ceramic capacitor between VCC (pin 14) and GND (pin 7) as close as possible - ideally within 5 mm - to minimize high-frequency supply impedance. Use short, wide traces for both pins, avoid routing sensitive analog signals beneath the IC, and ensure solid GND plane coverage under the TSSOP-14 body to reduce ground bounce and EMI coupling.
