Product details
Overview
CD74HC366M96 from Texas Instruments is a high-speed CMOS hex inverting buffer/line driver with three-state outputs, designed for bus interface and data routing in industrial control and instrumentation systems. It features non-inverting enable logic (active-low OE1/OE2), 6 independent inverting channels, 9 ns typical propagation delay at 5 V/15 pF, ±25 mA output drive, and operation across –55°C to 125°C.
For engineers reviewing the CD74HC366M96 datasheet, CD74HC366M96 pinout, CD74HC366M96 application, or CD74HC366M96 equivalent, this page delivers verified technical context, package-validated pin functions, real-world use cases in bus buffering and level translation, and two confirmed alternative parts with documented functional and application differences.
Technical Context
The CD74HC366M96 implements six independent inverting buffer gates, each with high-current CMOS outputs capable of driving up to 15 LSTTL loads. Its dual active-low output-enable inputs (OE1, OE2) are internally NORed to simultaneously place all six outputs in high-impedance state.
It operates from 2 V to 6 V supply, exhibits balanced tPLH/tPHL transition times (≤15 ns max at 6 V), and maintains CMOS input compatibility (II ≤ 1 µA) with 30% noise immunity at VCC = 5 V. The device supports hot-swap-capable bus interfacing via controlled three-state timing (tPLZ/tPZL ≤ 38 ns at 6 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Hex inverting buffer with three-state outputs - enables bidirectional bus control and signal polarity inversion |
| Supply Voltage Range | 2 V to 6 V - supports mixed-voltage system interfacing and low-power operation down to 2 V |
| Propagation Delay (tPLH/tPHL) | 9 ns typical at VCC = 5 V, CL = 15 pF - ensures sub-10 ns timing margin for 50 MHz bus clocking |
| Output Drive Strength | ±25 mA per output - drives heavy capacitive loads (e.g., >100 pF buses) without external buffers |
| Operating Temperature | –55°C to +125°C - qualified for extended industrial, automotive under-hood, and military-grade applications |
| Input Leakage Current | ±1 µA max at TA = –55°C to 125°C - guarantees stable logic thresholds with floating-input immunity |
| Three-State Leakage | ±10 µA max at VO = VCC/GND - prevents bus contention during high-Z state in multi-driver systems |
Pinout & Package
CD74HC366M96 is packaged in a 16-pin SOIC (D) with 9.90 mm × 3.90 mm body size, 1.27 mm pitch, and RoHS-compliant NiPdAu lead finish. Moisture sensitivity level is Level-1 (unlimited floor life at ≤30°C/60% RH).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15 | OE1, OE2 | Active-low output enable inputs - both must be low to activate outputs; internally NORed for single-point control |
| 2, 4, 6, 10, 12, 14 | 1A–6A | Inverting input terminals - accept standard CMOS/TTL logic levels; buffered for noise rejection |
| 3, 5, 7, 9, 11, 13 | 1Y–6Y | Inverting three-state outputs - drive bus lines with polarity inversion and high-Z disable capability |
| 8 | GND | Ground reference - must be low-impedance connection to minimize ground bounce in fast switching |
| 16 | VCC | Power supply - requires local 0.1 µF ceramic bypass capacitor placed within 5 mm of pin |
Key Features
| Feature | Design Value |
|---|---|
| High-current bus driver outputs | ±25 mA sink/source per channel - eliminates need for external line drivers in 16-bit parallel bus designs |
| Three-state control architecture | Dual NORed OE inputs - simplifies PCB layout by enabling shared enable signals across multiple devices |
| Low power consumption | 160 µA max ICC over full temperature range - reduces thermal load in dense logic arrays |
| Wide supply voltage tolerance | 2 V to 6 V operation - allows direct interface between 3.3 V microcontrollers and 5 V legacy peripherals |
| Robust noise immunity | 30% VIH/VIL hysteresis at VCC = 5 V - suppresses false triggering in electrically noisy industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverting buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC366N | Same logic function and pinout; PDIP-16 package only; wider 19.3 mm × 6.35 mm footprint | Preferred for through-hole prototyping or legacy board rework where SOIC reflow is unavailable | Select when manual soldering, socket-based testing, or compatibility with existing DIP layouts is required |
| CD74HCT366M96 | LSTTL-compatible inputs (VIH ≥ 2 V, VIL ≤ 0.8 V); identical SOIC-16 packaging and timing | Better suited for mixed-logic systems with legacy 74LS TTL outputs driving HC366 inputs | Choose when interfacing directly to 74LS-series logic without pull-up resistors or level shifters |
Compared with SN74HC366N and CD74HCT366M96, the CD74HC366M96 offers optimal space efficiency in SOIC packaging and native CMOS input compatibility-making it ideal for high-density 3.3 V/5 V mixed-signal boards where layout area and input threshold matching are critical.

FAQ
What is the logic function of CD74HC366M96?
The CD74HC366M96 is a hex inverting three-state buffer. Each of its six channels accepts a logic input (A) and produces an inverted output (Y) when enabled; outputs enter high-impedance state when either OE1 or OE2 is high. This function is explicitly defined in the device functional table (Section 7.3) and logic diagram of the TI datasheet SCHS180D.
Does CD74HC366M96 support 3.3 V operation?
Yes, CD74HC366M96 supports 3.3 V operation fully - its specified supply range is 2 V to 6 V, and all electrical characteristics (including VIH/VIL thresholds, propagation delay, and output drive) are guaranteed across that range per Section 5.2 and 5.4 of the datasheet.
What is the maximum output current per pin for CD74HC366M96?
The CD74HC366M96 provides ±25 mA DC output source/sink current per pin, as specified in Section 5.1 Absolute Maximum Ratings and validated in Section 5.4 Electrical Characteristics under VOH/VOL test conditions at VCC = 6 V and TA = –55°C to 125°C.
How are the OE1 and OE2 pins used in CD74HC366M96?
In CD74HC366M96, OE1 (Pin 1) and OE2 (Pin 15) are active-low inputs internally NORed - meaning all six outputs go high-impedance if either OE is high, and all outputs become active (inverting) only when both OE1 and OE2 are low. This behavior is confirmed in the Function Table (Table 7-1) and Functional Block Diagram (Section 7.2).
Is CD74HC366M96 pin-compatible with CD74HC365M96?
No - CD74HC366M96 is not pin-compatible with CD74HC365M96. While both share the same SOIC-16 package and pin count, their logic functions differ: CD74HC365M96 is non-inverting, whereas CD74HC366M96 is inverting. Pin assignments for inputs/outputs match, but signal polarity is reversed, requiring firmware or schematic revision for substitution.
