Product details
Overview
74HC366PW,118 from Nexperia is a hex inverting buffer/line driver with 3-state outputs, designed for bus interface and signal isolation in digital systems. It operates across 2.0 V to 6.0 V supply, delivers propagation delay as low as 10 ns at VCC = 6.0 V, supports -40 °C to +125 °C ambient range, and features dual active-low output enable inputs (OE1, OE2) for independent control of three buffer pairs. It is used in industrial PLC I/O modules to isolate microcontroller GPIOs from noisy field-side signals.
For engineers reviewing the 74HC366PW,118 datasheet, 74HC366PW,118 pinout, 74HC366PW,118 application, or 74HC366PW,118 equivalent, this page provides verified functional behavior, validated TSSOP16 pin mapping, confirmed static/dynamic specs per Rev. 7 (March 2024), and real-world use cases in bus-driven logic systems requiring level translation and output tri-stating.
Technical Context
The device implements six independent inverting buffers, each with complementary input-to-output logic (1A → 1Y = NOT). Output states are controlled by two separate active-low enables: OE1 governs buffers 1–3 (pins 1,2,3 → 3,5,7), OE2 governs buffers 4–6 (pins 10,12,14 → 9,11,13). Inputs include clamp diodes enabling safe interfacing to voltages exceeding VCC when current-limiting resistors are used.
It adheres to JEDEC JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V) standards, exhibits CMOS-level input thresholds (VIH = 4.2 V min at VCC = 6.0 V), and maintains high noise immunity with typical VIH/VIL margins >1.5 V under full temperature range. Latch-up performance exceeds 100 mA per JESD78 Class II Level B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.0 V to 6.0 V - Enables direct interface with 3.3 V and 5 V logic families without level shifters. |
| Propagation Delay | 10 ns max at VCC = 6.0 V, CL = 50 pF - Supports reliable operation in 50 MHz+ digital buses with timing margin. |
| Output Drive | ±6.0 mA at VCC = 4.5 V - Sufficient to drive standard TTL loads or multiple CMOS inputs (fan-out ≥ 10). |
| 3-State Leakage | ±0.5 μA max at VCC = 6.0 V - Ensures minimal bus contention current when outputs are disabled. |
| Operating Temperature | -40 °C to +125 °C - Qualified for extended industrial environments including motor drives and power converters. |
| Input Clamp Diodes | Integrated - Allows safe connection of inputs to voltages up to VCC + 0.5 V using external series resistors. |
| Power Dissipation | 500 mW max (TSSOP16) - Derates linearly at 8.5 mW/K above 91 °C, supporting thermal design in compact PCB layouts. |
Pinout & Package
TSSOP16 plastic thin shrink small outline package (SOT403-1), 16-pin, body width 4.4 mm, lead pitch 0.65 mm, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15 | OE1, OE2 | Active-low output enable inputs - Independently disable first three (pin 1) or last three (pin 15) buffer outputs to high-impedance state. |
| 2, 4, 6, 10, 12, 14 | 1A–6A | Inverting data inputs - Each drives corresponding inverted output (e.g., pin 2 → pin 3); CMOS-compatible thresholds. |
| 3, 5, 7, 9, 11, 13 | 1Y–6Y | Inverting buffered outputs - Provide logic inversion and current gain; support 3-state control via OE pins. |
| 8 | GND | Ground reference - Must be low-impedance connection to minimize ground bounce in multi-buffer switching. |
| 16 | VCC | Positive supply - Decoupling capacitor (100 nF) required within 5 mm for stable high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 2.0–6.0 V operation allows single part to serve both 3.3 V microcontrollers and legacy 5 V peripherals. |
| Independent 3-State Control | Dual OE inputs enable selective bus partitioning - e.g., isolate sensor interface (OE1) while keeping display driver active (OE2). |
| High Noise Immunity | Typical VIH-VIL margin >2.0 V at VCC = 4.5 V ensures robustness against EMI in industrial enclosures. |
| ESD Protection | HBM >2000 V and CDM >1000 V reduce risk of damage during board assembly and handling. |
| Latch-Up Immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during transient overvoltage events. |
Applications
| Industrial Bus Interface | Microcontroller GPIO Expansion |
|---|---|
Use Scenario: Isolating MCU SPI/I²C lines from high-noise motor drive circuits in factory automation controllers. IC Role / Device Role / Timing Role: Inverting buffer with 3-state control acts as bidirectional bus isolator; OE pins synchronized to communication frame boundaries.

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,118 | TTL-compatible inputs (VIH = 2.0 V min), identical pinout and 3-state behavior. | Better suited for mixed 5 V TTL/CMOS systems where input thresholds must match legacy logic families. | Select when interfacing with older 5 V microcontrollers or ASICs with TTL input levels. |
| SN74LVC366APWR | Lower VCC range (1.65–3.6 V), higher speed (tpd = 5.4 ns typ at 3.3 V), same 16-pin TSSOP package. | Optimized for modern low-voltage embedded systems; not compatible with 5 V operation or 6 V absolute max ratings. | Choose for battery-powered or 3.3 V-only designs requiring faster timing and lower quiescent current. |
Compared with 74HCT366PW,118, the 74HC366PW,118 offers superior noise margin in mixed-voltage systems but lacks TTL input compatibility; versus SN74LVC366APWR, it supports wider supply range and higher voltage tolerance at the cost of slightly higher propagation delay and static current.

FAQ
What is the maximum output current per channel for 74HC366PW,118?
The device supports ±6.0 mA DC output current per channel at VCC = 4.5 V, with ±7.8 mA specified at VCC = 6.0 V. Absolute maximum output current is ±35 mA, but sustained operation above ±6.0 mA requires thermal derating per the TSSOP16 power dissipation curve (8.5 mW/K above 91 °C).
Can 74HC366PW,118 drive a 50 pF load at 10 MHz without signal degradation?
Yes - with tpd = 12 ns typ and tt = 5 ns typ at VCC = 4.5 V, CL = 50 pF, the device meets setup/hold timing for 10 MHz clocks. Its CPD = 30 pF per buffer ensures dynamic power remains below 1.5 mW per channel at that frequency, minimizing jitter and overshoot.
How does the dual OE architecture improve system-level design?
The separate OE1 and OE2 inputs allow independent control of two groups of three buffers, enabling time-multiplexed bus sharing - e.g., one group for sensor data and another for actuator control - reducing need for additional logic or multiplexers while maintaining deterministic signal routing.
Is 74HC366PW,118 qualified for automotive applications?
No - this part is not AEC-Q100 qualified and is intended for industrial and commercial use only. While it operates from -40 °C to +125 °C, it lacks automotive-specific stress testing, failure mode analysis, and PPAP documentation required for safety-critical vehicle subsystems.
