Product details
Overview
74HC366PW-Q100 from Nexperia is an automotive-qualified hex inverting buffer/line driver with 3-state outputs, operating across 2.0 V to 6.0 V supply, supporting -40 °C to +125 °C ambient range, featuring CMOS-level inputs and ≤20 ns propagation delay at 4.5 V, used for bidirectional bus interfacing and signal isolation in automotive body control modules.
For engineers reviewing the 74HC366PW-Q100 datasheet, 74HC366PW-Q100 pinout, 74HC366PW-Q100 application, or 74HC366PW-Q100 equivalent, this device serves as a high-noise-immunity, AEC-Q100 Grade 1-compliant logic buffer enabling controlled signal routing in automotive powertrain and infotainment subsystems where voltage-level translation and output disable capability are required.
Technical Context
This IC implements six independent inverting buffer stages, each with active-low 3-state enable (OE1/OE2), allowing selective output disabling without affecting input states. Its dual OE inputs support grouped control of three buffers per enable line, optimizing bus arbitration logic in multi-node systems.
The device uses standard CMOS silicon process with input clamp diodes enabling safe interface to voltages exceeding VCC when current-limiting resistors are applied. It complies with JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V), and meets AEC-Q100 Grade 1 stress testing including latch-up >100 mA per JESD78 Class II Level B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - supports direct interface with 3.3 V and 5 V logic domains without level shifters. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive applications per AEC-Q100 Grade 1. |
| Propagation Delay | ≤20 ns at VCC = 4.5 V, CL = 50 pF - ensures timing integrity in 25 MHz+ digital control loops. |
| Output Drive Strength | ±7.8 mA at VCC = 6.0 V - sufficient to drive 50 pF loads over 10 cm PCB traces without signal degradation. |
| Input Thresholds | VIH = 3.15 V (min), VIL = 1.35 V (max) at VCC = 4.5 V - provides 1.8 V noise margin for robust CMOS-level operation. |
| 3-State Leakage | IOZ ≤ ±0.5 μA at VCC = 6.0 V - minimizes standby current in disabled channels during sleep-mode operation. |
| Power Dissipation | CPD = 30 pF per buffer - enables accurate dynamic power estimation for thermal design in dense PCB layouts. |
Pinout & Package
TSSOP16 plastic thin shrink small outline package (SOT403-1), 16-pin, 4.4 mm body width, 0.65 mm pitch, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15 | OE1, OE2 | Active-low output enable inputs controlling groups of three buffers; simultaneous assertion disables all six outputs to high-impedance state. |
| 2, 4, 6, 10, 12, 14 | 1A–6A | Inverting data inputs; each drives corresponding output with polarity inversion and full rail-to-rail swing. |
| 3, 5, 7, 9, 11, 13 | 1Y–6Y | Inverting buffered outputs; present inverted copy of respective input when enabled, float when OE asserted. |
| 8 | GND | Reference ground terminal; must be low-impedance connection to minimize switching noise coupling into logic thresholds. |
| 16 | VCC | Primary supply rail; decoupling capacitor (100 nF ceramic) required within 5 mm for stable high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use up to +125 °C ambient, including temperature cycling, humidity bias, and ESD stress per JEDEC standards. |
| Input clamp diodes | Enable safe interface to signals up to VCC + 0.5 V using external current-limiting resistors-critical for mixed-voltage board designs. |
| High noise immunity | Typical noise margin >1.8 V at 4.5 V supply ensures reliable operation in electrically noisy engine bay environments. |
| Low static current | ICC ≤ 8.0 μA typical at 6.0 V and 25 °C - reduces quiescent power in always-on vehicle modules. |
| 3-state output control | Dual OE pins allow partitioned bus management: OE1 controls buffers 1–3, OE2 controls buffers 4–6, simplifying arbitration logic. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverting buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT366PW-Q100 | TTL-compatible inputs (VIH = 2.0 V min), higher ICC at 5 V (≤80 μA typ), identical pinout and timing. | Better suited for legacy 5 V microcontrollers with TTL output levels; less suitable for 3.3 V-only systems. | Select when interfacing with older MCUs or FPGAs lacking CMOS-level drive strength. |
| SN74LVC366APWRE4 | Lower VCC range (1.65–3.6 V), faster tpd (≤5.5 ns at 3.3 V), non-automotive grade (industrial only). | Not AEC-Q100 qualified; unsuitable for under-hood deployment but ideal for infotainment head unit baseband logic. | Choose for cost-sensitive, non-safety-critical 3.3 V applications where automotive qualification is not required. |
Compared with 74HC366PW-Q100, the 74HCT366PW-Q100 offers broader input compatibility with legacy 5 V logic but sacrifices low-voltage operation below 4.5 V, while the SN74LVC366APWRE4 delivers superior speed and power efficiency at 3.3 V but lacks automotive qualification and thermal robustness.

FAQ
What is the maximum clock frequency supported by the 74HC366PW-Q100?
The 74HC366PW-Q100 is not a clocked device-it has no internal clock and operates asynchronously. Its usable signal frequency depends on propagation delay and load capacitance: at 4.5 V and 50 pF, tpd ≤20 ns supports clean edge transmission up to ~25 MHz for repetitive toggling, assuming proper PCB layout and termination.
Can OE1 and OE2 be tied together for single-enable operation?
Yes-OE1 and OE2 may be connected to a common control signal. Doing so enables or disables all six outputs simultaneously. This configuration is electrically valid and commonly used in bus isolation applications where grouped control is acceptable and simplifies MCU GPIO usage.
Does the 74HC366PW-Q100 support mixed-voltage operation (e.g., 3.3 V inputs driving 5 V outputs)?
No-the device is a pure buffer with no level-shifting capability. Inputs and outputs operate referenced to the same VCC rail. To interface 3.3 V logic to a 5 V bus, external series resistors and clamping diodes (as documented in Section 1) must be used to limit input current when VI exceeds VCC.
How does the 74HC366PW-Q100 handle input signals exceeding VCC?
Internal input clamp diodes conduct when VI < −0.5 V or VI > VCC + 0.5 V. To prevent damage, external current-limiting resistors must restrict IIK to ≤±20 mA (per Absolute Maximum Ratings). This allows safe interfacing to higher-voltage signals-e.g., 12 V sensor outputs-with appropriate resistor sizing.
