Product details
Overview
74HC366D,653 from Nexperia is a hex inverting buffer/line driver with 3-state outputs, designed for bus interface and data routing in digital systems. It features dual active-low output enable inputs (OE1, OE2), operates from 2.0 V to 6.0 V, delivers propagation delay as low as 10 ns at VCC = 6.0 V, and supports industrial temperature range up to +125 °C - used in programmable logic controllers and industrial I/O modules.
For engineers reviewing the 74HC366D,653 datasheet, 74HC366D,653 pinout, 74HC366D,653 application, or 74HC366D,653 equivalent, key selection criteria include 3-state output timing (enable/disable times ≤38 ns), CMOS-level input compatibility, SO16 package thermal derating (12.4 mW/K above 110 °C), and guaranteed high-impedance isolation (IOZ ≤ ±0.5 μA at VCC = 6.0 V).
Technical Context
The device implements six independent inverting buffers, each with separate input (nA) and output (nY) terminals, controlled collectively by two shared active-low output enables (OE1 on Pin 1, OE2 on Pin 15). Output state transitions follow strict 3-state logic: only when both OE1 and OE2 are LOW do outputs drive inverted logic; any HIGH on either enable forces all six outputs into high-impedance OFF-state.
Input clamp diodes allow safe interfacing to voltages exceeding VCC when current-limiting resistors are used. Static characteristics are specified across -40 °C to +125 °C, with VIH ≥ 4.2 V and VOL ≤ 0.26 V at VCC = 6.0 V and IO = 7.8 mA, ensuring robust noise immunity and rail-to-rail compatibility in mixed-voltage systems.
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. |
| Propagation Delay (tpd) | 10 ns (typ) at VCC = 6.0 V, CL = 50 pF - enables reliable operation in 50 MHz+ digital buses. |
| 3-State Enable Time (ten) | 13 ns (typ) at VCC = 6.0 V - ensures fast bus arbitration and minimal contention window during output activation. |
| Off-State Output Current (IOZ) | ±0.5 μA max at VCC = 6.0 V - guarantees strong high-impedance isolation to prevent signal leakage between shared bus lines. |
| Input Clamp Diode Support | Yes - permits safe connection of inputs to voltages > VCC using external current-limiting resistors. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood industrial control and motor drive applications. |
| Power Dissipation Capacitance (CPD) | 30 pF per buffer - enables accurate dynamic power estimation (PD = CPD × VCC² × fi × N) for thermal design. |
Pinout & Package
74HC366D,653 is housed in a plastic small outline package (SO16), SOT109-1, with 16 leads and 3.9 mm body width. Pin 1 is index-marked; pin 16 is VCC; pin 8 is GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15 (OE1, OE2) | Active-low output enable | Both must be LOW for output drivers to be active; either HIGH places all six outputs in high-Z state. |
| 2, 4, 6, 10, 12, 14 (1A–6A) | Data input | Inverting inputs driving corresponding Y outputs; CMOS-compatible thresholds (VIH ≥ 4.2 V @ VCC = 6.0 V). |
| 3, 5, 7, 9, 11, 13 (1Y–6Y) | Inverting buffered output | Drive-strength matched to sink/source 7.8 mA while maintaining VOL ≤ 0.26 V and VOH ≥ 5.48 V. |
| 8 | GND | Reference ground for all I/O and supply; decoupling capacitor placement critical for noise immunity. |
| 16 | VCC | Primary supply rail; requires local 100 nF ceramic decoupling adjacent to pin for stable switching performance. |
Key Features
| Feature | Design Value |
|---|---|
| Hex inverting 3-state buffering | Six independent channels with shared dual-OE control - ideal for bidirectional bus transceivers and address/data latching. |
| Wide supply voltage range | 2.0 V to 6.0 V operation - eliminates need for separate voltage translators in mixed-supply systems. |
| High noise immunity | VIH/VIL margins ≥ 1.2 V at VCC = 4.5 V - rejects EMI in electrically noisy factory-floor environments. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during transient overvoltage events. |
| ESD protection | HBM > 2000 V, CDM > 1000 V - withstands handling and board assembly without special ESD precautions. |
Applications
| Industrial PLC Backplane Interface | Digital I/O Expansion Module |

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 | TTL-compatible inputs (VIH = 2.0 V min); identical pinout and timing specs except slightly higher ICC at VCC = 5.5 V. | Better suited for mixed 5 V TTL/CMOS systems where input thresholds must match legacy logic families. | Select when interfacing with 74LS or other TTL-series devices without level-shifting circuitry. |
| SN74LVC366APWR | 3.3 V only (1.65–3.6 V), lower VCC max, faster tpd (5.8 ns typ @ 3.3 V), but no input clamping diodes. | Targeted at modern low-voltage FPGAs and SoCs; unsuitable for >3.6 V or overvoltage-tolerant designs. | Choose for space-constrained 3.3 V applications requiring sub-6 ns delay and smaller TSSOP16 footprint. |
Compared with 74HCT366D,653, the 74HC366D,653 offers superior noise margin in pure CMOS systems and overvoltage input tolerance, while SN74LVC366APWR trades voltage flexibility for speed and density - making the 74HC366D,653 optimal for industrial 5 V backplanes requiring robustness and wide-VCC operation.

FAQ
What is the maximum clock frequency supported by 74HC366D,653?
The 74HC366D,653 does not operate on a clock; it is an asynchronous buffer. Its usable data rate is determined by propagation delay (10 ns typical at VCC = 6.0 V) and load conditions. For clean 50% duty-cycle signals with CL = 50 pF, reliable operation extends beyond 50 MHz in point-to-point configurations, assuming proper PCB layout and termination.
Can OE1 and OE2 be tied together for single-enable operation?
Yes - OE1 (Pin 1) and OE2 (Pin 15) can be connected to a common control signal. Doing so reduces enable granularity but simplifies logic design. When tied, both enables behave as a single active-low input; the functional truth table remains valid, and no timing or electrical penalty occurs per datasheet specifications.
Does 74HC366D,653 support hot-swap or live-insertion?
No - the device lacks built-in hot-swap protection. Input clamp diodes permit limited overvoltage tolerance (with external current limiting), but uncontrolled insertion into a live bus risks latch-up or damage due to supply sequencing violations and transient currents. Use only in statically powered systems or with external hot-swap controllers.
How does the 74HC366D,653 differ from the 74HC367?
The 74HC367 is a hex non-inverting buffer with identical 3-state architecture and pinout, whereas the 74HC366D,653 provides inverting logic. All electrical specs, timing, package, and enable behavior are identical - the sole functional difference is polarity inversion at each output (nY = NOT nA vs. nY = nA), dictating use in complement-sensitive bus protocols or logic inversion stages.
