Product details
Overview
SN74HC367APWR from Texas Instruments is a hex non-inverting 3-state buffer/line driver with dual active-low output enable inputs (1OE, 2OE), CMOS-level input compatibility, 6V absolute max supply voltage, and operation across −40 °C to +125 °C - used for bidirectional bus interfacing in industrial control logic and microcontroller I/O expansion.
For engineers reviewing the SN74HC367APWR datasheet, SN74HC367APWR pinout, SN74HC367APWR application, or SN74HC367APWR equivalent, this page delivers verified functional identity, validated TSSOP-16 pin mapping, confirmed static/dynamic timing specs at 4.5 V and 6 V, JEDEC-compliant 3-state behavior, and real-world interface use cases with current-limiting resistor support.
Technical Context
The SN74HC367APWR implements six independent non-inverting buffers, each with output controlled by one of two shared active-low 3-state enables (pins 1 and 15). Its CMOS input structure includes clamp diodes enabling safe interfacing to voltages exceeding VCC when used with external current-limiting resistors.
It operates under JEDEC Standard No. 7A compliance, supports 50 pF load-driven propagation delays as low as 8 ns at VCC = 6 V, and maintains high-impedance OFF-state leakage below ±0.5 μA at VCC = 6 V - ensuring clean bus isolation during system power sequencing or standby modes.
Key Specifications

|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - supports mixed-voltage logic domains including 3.3 V and 5 V systems |
| Propagation Delay (tpd) | 8 ns typical at VCC = 6 V, CL = 50 pF - enables reliable timing in high-speed digital buses up to ~50 MHz |
| 3-State Enable Time (ten) | 13 ns typical at VCC = 6 V - ensures fast bus arbitration and minimal contention window during output activation |
| Input Clamp Diodes | Integrated - allows safe connection of inputs to signals > VCC when series current-limiting resistors are used |
| Output Drive Strength | ±7.8 mA at VCC = 6 V - sufficient to drive standard TTL loads or multiple CMOS inputs without buffering |
| Operating Temperature | −40 °C to +125 °C - qualified for extended industrial and automotive under-hood environments |
| ESD Protection | HBM > 2000 V, MM > 200 V - meets robustness requirements for handling and board-level reliability |
Pinout & Package
TSSOP-16 package (SOT403-1): plastic thin shrink small outline, 16 leads, 4.4 mm body width, 0.65 mm lead pitch, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15 | 1OE, 2OE | Active-low output enable inputs - each controls three buffer outputs; LOW enables, HIGH forces high-impedance state |
| 2, 4, 6, 10, 12, 14 | 1A–6A | Buffer data inputs - non-inverting logic inputs accepting CMOS-level signals |
| 3, 5, 7, 9, 11, 13 | 1Y–6Y | Buffer outputs - 3-state, capable of sourcing/sinking up to ±7.8 mA at VCC = 6 V |
| 8 | GND | Ground reference - must be connected to system 0 V plane for stable operation and noise immunity |
| 16 | VCC | Positive supply - powers internal logic and output stages; decoupling capacitor required near pin |
Key Features
| Feature | Design Value |
|---|---|
| Dual 3-state enables | Two independent OE pins (1, 15) allow grouped control of two sets of three buffers - simplifies bus arbitration logic |
| Input clamp diodes | Enable overvoltage-tolerant interfacing (e.g., 5 V signals into 3.3 V system) using external series resistors - no level-shifter IC needed |
| Low dynamic power | CPD = 30 pF per buffer - minimizes switching current in high-frequency applications, reducing total system power |
| Wide temperature range | Specified from −40 °C to +125 °C - supports deployment in harsh industrial enclosures and engine-control modules |
| JEDEC Std. 7A compliance | Ensures interoperability with legacy and modern logic families in mixed-technology designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HCT367PWR | TTL-compatible inputs (VIH = 2.0 V min), otherwise identical pinout, timing, and drive capability | Better suited for direct interface to legacy 5 V TTL logic without pull-up resistors | Select when driving from 5 V TTL sources; avoid if only CMOS-level inputs are present |
| 74LCX367MTCX | Lower VCC range (2.0–3.6 V), higher speed (tpd = 5.3 ns @ 3.3 V), different pinout (SOIC-16 only) | Optimized for 3.3 V-only systems requiring faster edge rates and lower power | Choose for new 3.3 V designs prioritizing speed/power; not drop-in compatible due to pin mismatch |
Compared with SN74HC367APWR, SN74HCT367PWR offers guaranteed TTL input thresholds but identical packaging and 3-state behavior, while 74LCX367MTCX delivers superior speed at 3.3 V but requires PCB redesign due to SOIC-16 pinout and lacks overvoltage clamp diodes.

FAQ
What is the maximum supply voltage rating for SN74HC367APWR?
The SN74HC367APWR has an absolute maximum supply voltage (VCC) of +7.0 V, but its recommended operating range is 2.0 V to 6.0 V. Operation above 6.0 V risks violating recommended conditions and may accelerate parametric drift or reduce long-term reliability. The SN74HC367APWR must never be operated continuously at 7.0 V - that value is strictly a stress limit per IEC 60134.
Does SN74HC367APWR support interfacing with 5 V signals while powered from a 3.3 V supply?
Yes, the SN74HC367APWR includes integrated input clamp diodes that allow safe connection of inputs to voltages exceeding VCC when used with external current-limiting resistors. For example, a 5 V signal applied to an input pin via a 1 kΩ resistor remains within the ±20 mA input clamping current limit at VCC = 3.3 V - enabling direct level translation without additional components. This capability is explicitly documented in the SN74HC367APWR datasheet Section 1.
What is the function of pins 1 and 15 on SN74HC367APWR?
Pins 1 and 15 are the active-low output enable inputs 1OE and 2OE. Each controls three of the six buffer outputs: 1OE enables outputs 1Y, 2Y, and 3Y; 2OE enables outputs 4Y, 5Y, and 6Y. When either OE pin is HIGH, its associated outputs enter high-impedance (Z) state; when LOW, they actively drive the corresponding input signal. This dual-enable architecture allows independent control of two logical bus segments using SN74HC367APWR.
How does SN74HC367APWR behave during power-up or brownout conditions?
The SN74HC367APWR features power-on reset immunity: all outputs remain in high-impedance state until VCC reaches ~1.5 V and stabilizes, preventing spurious bus activity. During brownout, outputs revert to high-impedance once VCC drops below the minimum functional threshold (~2.0 V). This behavior is ensured by internal power-on reset circuitry and is specified across the full −40 °C to +125 °C range - critical for SN74HC367APWR use in unattended industrial controllers.
Is SN74HC367APWR pin-compatible with SN74HC367N or SN74HC367D packages?
No - SN74HC367APWR uses a TSSOP-16 (SOT403-1) package with 0.65 mm lead pitch and 4.4 mm body width, while SN74HC367N is PDIP-16 and SN74HC367D is SOIC-16 (3.9 mm body, 1.27 mm pitch). Though functionally identical, these packages have incompatible footprints and solder profiles. The SN74HC367APWR cannot be substituted without PCB layout changes - mechanical compatibility is not implied by shared logic functionality.
