Product details
Overview
74HCT366PW,112 from Nexperia is a hex inverting 3-state buffer/line driver in TSSOP16 package, operating from 4.5 V to 5.5 V with TTL-compatible inputs, 16 ns typical propagation delay at 4.5 V, and ±6 mA output drive-used for bidirectional bus interfacing and address/data line isolation in industrial control logic systems.
For engineers reviewing the 74HCT366PW,112 datasheet, 74HCT366PW,112 pinout, 74HCT366PW,112 application, or 74HCT366PW,112 equivalent, this device serves as a high-noise-immunity, temperature-stable (−40 °C to +125 °C) logic-level translator and bus driver where precise timing control, low static current (<160 μA), and robust 3-state enable sequencing are required.
Technical Context
The 74HCT366PW,112 implements six independent inverting buffers, each with active-low 3-state output control via dual OE inputs (OE1 on pin 1, OE2 on pin 15). Its TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5 V) ensure reliable interfacing with legacy 5 V logic families.
Each buffer delivers rail-to-rail CMOS outputs with VOH ≥ 3.7 V and VOL ≤ 0.4 V under full load (IO = ±6 mA), while maintaining high-impedance OFF-state leakage < ±10 μA across its full operating temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - Ensures compatibility with standard 5 V TTL and mixed-voltage logic systems without level-shifting. |
| Propagation Delay | 13–36 ns (typ/max at VCC = 4.5 V) - Enables reliable operation up to ~20 MHz bus clocking in synchronous digital interfaces. |
| Output Drive | ±6.0 mA - Sufficient to drive 50 pF loads with controlled edge rates (tt ≤ 18 ns), supporting multi-drop bus topologies. |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - Matches standard TTL logic levels, eliminating need for external biasing or translation. |
| Static Current | ≤160 μA at +125 °C - Supports low-power standby modes in thermally demanding industrial environments. |
| Operating Temp | −40 °C to +125 °C - Qualified for extended-temperature industrial and automotive-adjacent applications without derating. |
| ESD Rating | HBM >2000 V, CDM >1000 V - Provides robust handling margin during PCB assembly and field service. |
Pinout & Package
TSSOP16 plastic thin shrink small outline package (SOT403-1), 16-pin, body width 4.4 mm, 0.65 mm pitch, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15 | OE1, OE2 | Active-low 3-state enable inputs - Independently disable buffer pairs (1Y/2Y, 3Y/4Y, 5Y/6Y) to prevent bus contention. |
| 2, 4, 6, 10, 12, 14 | 1A–6A | Inverting data inputs - Each drives corresponding inverted output; clamped diodes allow safe overvoltage tolerance (>VCC). |
| 3, 5, 7, 9, 11, 13 | 1Y–6Y | Inverting 3-state outputs - High-impedance when OE = HIGH; logic inversion enables signal polarity correction in feedback paths. |
| 8 | GND | Ground reference - Shared return path for all I/O and supply currents; requires low-inductance PCB connection. |
| 16 | VCC | Positive supply - Must be decoupled locally (e.g., 100 nF ceramic) to suppress switching noise coupling into adjacent channels. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | VIH ≥ 2.0 V, VIL ≤ 0.8 V at 4.5–5.5 V - Direct interface with 74LS, 74F, and microcontroller GPIO without pull-ups or translators. |
| Dual independent OE control | OE1 (pin 1), OE2 (pin 15) - Enables selective tri-state grouping for partial bus isolation (e.g., address vs. data lanes). |
| High noise immunity | Typical noise margin >1.2 V - Maintains logic integrity in electrically noisy factory-floor PLC and motor-drive environments. |
| Clamped input diodes | Supports current-limiting resistor use for VI > VCC - Allows safe interfacing with 12 V sensor signals using simple series resistors. |
| Extended temperature range | −40 °C to +125 °C operation - Validated for use in enclosed industrial enclosures without forced cooling or derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverting 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT366D,653 | SO16 package (SOT109-1), wider body (3.9 mm), higher thermal resistance (12.4 mW/K derating above 110 °C) | Better suited for through-hole prototyping or high-reliability solder-joint applications; less space-efficient than TSSOP | Select when board real estate allows larger footprint and thermal management favors SO package. |
| SN74HCT366PWR | TSSOP16 from Texas Instruments; identical pinout and logic function but different AC specs (tpd max = 25 ns at 4.5 V) | Slightly slower timing margin; TI's characterization includes wider process variation across lot batches | Choose only if TI supply chain alignment or existing TI BOM consolidation outweighs 11 ns timing advantage of Nexperia part. |
Compared with 74HCT366D,653, the 74HCT366PW,112 offers 30 % smaller PCB area and superior thermal performance in compact layouts; versus SN74HCT366PWR, it delivers tighter propagation delay consistency critical for high-speed bus arbitration.

FAQ
What is the maximum output current per channel for 74HCT366PW,112?
The 74HCT366PW,112 supports ±6.0 mA DC output current per channel at VCC = 4.5 V, with VOL ≤ 0.4 V and VOH ≥ 3.7 V across −40 °C to +125 °C. This is verified per Table 7 (74HCT366 static characteristics) and applies to steady-state drive of standard LS-TTL loads or 50 pF capacitive buses.
Can 74HCT366PW,112 operate reliably at 3.3 V supply?
No - the 74HCT366PW,112 is specified only for 4.5 V to 5.5 V operation. At 3.3 V, input thresholds (VIH ≥ 2.0 V) remain valid, but output drive collapses: VOH drops below 2.4 V and VOL rises above 0.55 V, violating TTL and CMOS interface margins. Use 74LVC366 for 3.3 V systems.
How are OE1 and OE2 used in practice?
OE1 (pin 1) controls outputs 1Y and 2Y; OE2 (pin 15) controls 3Y–6Y. They are independent active-low enables - tying both low activates all six buffers; driving one high disables its pair while leaving others functional. This enables partial bus gating, e.g., isolating address lines (1Y–2Y) from data lines (3Y–6Y) during memory access cycles.
Is 74HCT366PW,112 pin-compatible with 74HC366PW?
Yes - both share identical TSSOP16 pinout (SOT403-1), same pin functions, and compatible DC specs. However, 74HC366PW uses CMOS input thresholds (VIH = 3.15 V min at 4.5 V), making it unsuitable for direct TTL input interfacing. Swapping requires verifying source logic family voltage levels.
