Product details
Overview
74HC366D,652 from Nexperia is a hex inverting 3-state buffer/line driver in SO16 package, operating from 2.0 V to 6.0 V supply, delivering 6.0 mA output drive at 4.5 V, with propagation delay as low as 12 ns (VCC = 4.5 V, Tamb = 25 °C), and specified for -40 °C to +125 °C industrial temperature range. It serves as a bidirectional bus interface isolator in microcontroller peripheral expansion systems.
For engineers reviewing the 74HC366D,652 datasheet, 74HC366D,652 pinout, 74HC366D,652 application, or 74HC366D,652 equivalent, this device is selected for high-noise-immunity digital signal buffering where CMOS-level input compatibility, low quiescent current (≤8.0 μA at VCC = 6.0 V), and precise 3-state timing control are required.
Technical Context
The 74HC366D,652 implements six independent inverting buffers, each with active-low 3-state enable (OE1, OE2) controlling two outputs per pair. Its logic function follows strict truth table behavior: when OE is LOW, output equals inverted input; when OE is HIGH, output enters high-impedance state.
It features input clamp diodes enabling safe interfacing to voltages exceeding VCC via external current-limiting resistors, and meets JESD78 Class II Level B latch-up immunity (>100 mA). ESD protection exceeds 2000 V HBM and 1000 V CDM per JEDEC standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - supports mixed-voltage system interfacing including 3.3 V and 5 V logic domains |
| Output Drive Capability | ±6.0 mA at VCC = 4.5 V - sufficient to drive standard TTL loads and moderate PCB trace capacitance |
| Propagation Delay | 12 ns typical (VCC = 4.5 V, CL = 50 pF) - enables reliable operation up to ~40 MHz data rates in buffered paths |
| 3-State Enable/Disable Time | 16 ns / 20 ns typical (VCC = 4.5 V) - ensures clean bus turnaround without contention in shared-data applications |
| Input Leakage Current | ±0.1 μA max (Tamb = 25 °C, VCC = 6.0 V) - minimizes loading on high-impedance source nodes |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood industrial and extended-range embedded control environments |
| Power Dissipation Capacitance | 30 pF per buffer - used to calculate dynamic power consumption in clocked or switching applications |
Pinout & Package
74HC366D,652 is housed in SO16 (SOT109-1) plastic small outline package: 16-pin, 3.9 mm body width, 1.27 mm lead pitch, gull-wing leads, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15 | OE1, OE2 | Active-low 3-state enable inputs - simultaneous assertion disables all six outputs to high-impedance |
| 2, 4, 6, 10, 12, 14 | 1A–6A | Inverting data inputs - each drives corresponding inverted output (1Y–6Y) when respective OE is LOW |
| 3, 5, 7, 9, 11, 13 | 1Y–6Y | Inverting buffered outputs - logic HIGH input yields logic LOW output; high-Z when OE = HIGH |
| 8 | GND | Ground reference - must be low-impedance connection to minimize noise coupling into CMOS inputs |
| 16 | VCC | Positive supply - decoupling capacitor (100 nF ceramic) required within 10 mm of pin for stable switching |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply voltage range | 2.0 V to 6.0 V - eliminates need for level shifters when interfacing 3.3 V MCU to 5 V peripherals |
| CMOS low power dissipation | ICC ≤ 8.0 μA at VCC = 6.0 V (25 °C) - suitable for battery-backed or always-on monitoring subsystems |
| High noise immunity | VIH/VIL thresholds scale with VCC (e.g., VIH ≥ 3.15 V at VCC = 4.5 V) - rejects transient noise up to 30% of rail |
| Input clamp diodes | Enables safe overvoltage tolerance - permits direct connection to 12 V signals using series current-limiting resistor |
| Industrial temperature grade | -40 °C to +125 °C operation - validated across full range without derating for automotive under-dash or motor-control applications |
Applications
| Industrial PLC I/O Expansion | Microcontroller Bus Isolation |

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,652 | TTL-compatible inputs (VIH = 2.0 V min), identical pinout and 3-state timing | Better interoperability with legacy 5 V TTL logic; slightly higher ICC at 5.5 V | Select when interfacing with older 74LS/74ALS families or mixed-signal boards with TTL-level control signals |
| SN74LVC366APWR | 3.3 V only (1.65–3.6 V), lower VCC, faster tpd (5.2 ns @ 3.3 V), different pin mapping (OE shared) | Not drop-in compatible; requires PCB redesign; superior for low-voltage, high-speed FPGA interfaces | Choose for new 3.3 V designs prioritizing speed and power efficiency over legacy compatibility |
Compared with 74HCT366D,652, the 74HC366D,652 offers tighter VIH/VIL margins at 5 V but lacks TTL input threshold compatibility; versus SN74LVC366APWR, it trades speed and voltage scaling for broader supply flexibility and pin-for-pin legacy support.

FAQ
What is the maximum output current per channel for 74HC366D,652?
The 74HC366D,652 delivers ±6.0 mA DC output current per channel at VCC = 4.5 V, with VOL ≤ 0.26 V and VOH ≥ 3.98 V under those conditions. Absolute maximum output current is ±35 mA, but sustained operation above ±6.0 mA risks exceeding recommended operating limits and thermal derating thresholds.
Can 74HC366D,652 interface directly with 5 V TTL logic inputs?
No - the 74HC366D,652 has CMOS-level inputs (VIH ≥ 3.15 V at VCC = 4.5 V), which may not reliably register as HIGH when driven by standard TTL outputs (VOH ≈ 2.4 V). For guaranteed TTL compatibility, use the pin-compatible 74HCT366D,652 variant, whose VIH threshold is 2.0 V minimum across its operating range.
How does the dual OE structure (OE1/OE2) function in practice?
OE1 controls outputs 1Y, 2Y, 3Y, and OE2 controls 4Y, 5Y, 6Y - enabling independent 3-state control of two groups of three buffers. This allows partial bus isolation, e.g., holding ADC data lines high-Z while keeping control lines active, reducing system-level contention without requiring separate ICs.
Is 74HC366D,652 qualified for automotive applications?
No - although rated for -40 °C to +125 °C, the 74HC366D,652 is not AEC-Q100 qualified and lacks automotive-specific validation (e.g., HTOL, EFT, ISO 11452-4 testing). Nexperia explicitly states non-automotive qualification in its legal disclaimers; use only in industrial or commercial systems unless independently validated per vehicle OEM requirements.
