Product details
Overview
SN74AHC367D from Texas Instruments is a hex noninverting buffer/line driver with 3-state outputs, designed for 2V–5.5V operation in bus interface and signal routing applications. It features dual independent output-enable controls (1OE, 2OE), ±8 mA drive strength at 5 V, 16-pin SOIC package, and operates across –40°C to +85°C.
For engineers reviewing the SN74AHC367D datasheet, SN74AHC367D pinout, SN74AHC367D application, or SN74AHC367D equivalent, this page delivers verified electrical specs, functional mode behavior, real-world timing performance at 3.3 V and 5 V, thermal resistance data, and precise pin-level circuit role mapping - all confirmed against TI's SCLS424G production datasheet (Rev. G, July 2024).
Technical Context
The SN74AHC367D implements six independent noninverting buffers grouped into two functional blocks: three buffers per side (1A1–1Y3 and 2A1–2Y2), each controlled by its own active-low enable (1OE, 2OE). Outputs enter high-impedance state when OE is high, enabling bidirectional bus control without external logic.
Its AHC logic family ensures CMOS-compatible input thresholds, rail-to-rail output swing, and propagation delays as low as 3.4 ns (tPLH, 5 V, CL = 15 pF). Input transition rate tolerance (20 ns/V at 5 V) and latch-up immunity (>100 mA per JESD78 Class II) support robust operation in mixed-voltage industrial systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2 V to 5.5 V - supports direct interfacing between 2.5 V, 3.3 V, and 5 V logic domains without level shifters. |
| IOH/IOL Drive | –8 mA / +8 mA at 5 V - sufficient to directly drive LEDs, TTL inputs, or short PCB traces without external buffers. |
| tPLH/tPHL | 3.4 ns min (5 V, CL = 15 pF) - enables reliable operation in sub-100 MHz digital control paths. |
| VIH/VIL Thresholds | 3.85 V max VIH / 1.65 V min VIL at 5.5 V VCC - ensures noise margin >0.7 V under worst-case supply and temperature. |
| ICC Quiescent Current | 4 µA typical (5.5 V) - suitable for low-power standby modes in battery-backed or energy-conscious designs. |
| RθJA | 73 °C/W (SOIC-16) - allows sustained 100 mW dissipation at TA = 85°C with minimal heatsinking. |
| ESD Rating | ±2000 V HBM - meets IEC 61000-4-2 Level 2 for handling in standard assembly environments. |
Pinout & Package
SN74AHC367D uses a 16-pin SOIC (D) package measuring 9.9 mm × 6.0 mm (body: 9.9 mm × 3.9 mm), with gull-wing leads and 1.27 mm pitch. Pin 1 is marked by a beveled corner or index area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15 | 1OE, 2OE | Active-low output enable inputs - tie high via pullup to ensure high-Z during power-up; control group isolation. |
| 2, 4, 6, 10, 12, 14 | 1A1–1A4, 2A1–2A2 | Buffer input pins - accept CMOS-level signals; must be tied to VCC or GND if unused to prevent floating. |
| 3, 5, 7, 9, 11, 13 | 1Y1–1Y4, 2Y1–2Y2 | Noninverting 3-state outputs - present A-input logic when OE is low; high-Z otherwise for bus sharing. |
| 8 | GND | Ground reference - connect to system ground plane with low-inductance path to minimize switching noise. |
| 16 | VCC | Power supply - bypass with 0.1 µF ceramic capacitor placed <2 mm from pin to suppress supply transients. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (2–5.5 V) | Enables single-bom reuse across 2.5 V, 3.3 V, and 5 V subsystems without redesign. |
| Dual independent 3-state enables | Allows selective activation of two 3-buffer groups - ideal for multiplexing address/data lines onto shared buses. |
| Low ICC quiescent current | Reduces system standby power - critical for always-on controllers and IoT edge nodes. |
| High noise immunity (20 ns/V input slew) | Rejects slow-rising signals and EMI-induced glitches on long traces or unshielded cables. |
| Latch-up immunity >100 mA | Prevents destructive failure during hot-plug events or transient overvoltage conditions. |
Applications
| Industrial PLC I/O Expansion | Automotive Body Control Module |
|---|---|
Use Scenario: Expanding discrete input/output capacity in programmable logic controllers using shared backplane buses. IC Role / Device Role / Timing Role: Buffers sensor status signals and drives relay coil drivers while isolating microcontroller GPIOs from bus noise.

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex buffer with 3-state output applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AHCT367D | TTL-compatible input thresholds (VIH = 2 V min at 4.5 V); identical pinout and drive strength. | Better suited for legacy 5 V TTL system integration where AHC's higher VIH may cause marginal recognition. | Select SN74AHCT367D only when interfacing with older 74LS/74F logic families requiring lower VIH. |
| 74LVC244APW | Octal (8-channel) configuration; 3.3 V only (1.65–3.6 V); 24 mA drive; TSSOP-20 package. | Higher channel count and drive for dense 3.3 V-only PCB layouts; not drop-in compatible due to pin count and voltage range. | Choose 74LVC244APW when expanding to 8 signals and operating exclusively at 3.3 V with higher fanout requirements. |
Compared with SN74AHC367D, SN74AHCT367D offers TTL input compatibility at the cost of reduced noise margin, while 74LVC244APW provides double the channel count and higher drive but requires board redesign and restricts VCC to 3.3 V systems.

FAQ
What is the maximum recommended operating temperature for SN74AHC367D?
The SN74AHC367D is rated for continuous operation from –40°C to +85°C ambient temperature. Its thermal resistance (RθJA = 73 °C/W in SOIC) allows junction temperatures to remain within safe limits (<125°C) even at full load in 85°C environments, provided proper PCB copper area and airflow are maintained per TI's layout guidelines.
Can SN74AHC367D drive LEDs directly?
Yes, SN74AHC367D can drive standard 20 mA LEDs directly: at 5 V VCC, it sources/sinks up to 8 mA per output (IOL/IOH), sufficient for low-current indicator LEDs. For higher-brightness LEDs, use an external transistor stage. Always include a series current-limiting resistor calculated as R = (VCC − VLED)/IOUT, referencing the device's VOL/VOH specs at the target current.
Is SN74AHC367D pin-compatible with SN74LS367N?
No, SN74AHC367D is not pin-compatible with SN74LS367N. While both are hex buffers with 3-state outputs, SN74LS367N uses a 16-pin PDIP package with different pin assignments (e.g., OE pins located at pins 1 and 16 vs. SN74AHC367D's pins 1 and 15). Electrical incompatibility (TTL vs. CMOS thresholds, supply range) further prevents direct substitution.
How should unused inputs be handled on SN74AHC367D?
All unused inputs on SN74AHC367D must be tied to either VCC or GND - never left floating. Floating CMOS inputs cause increased ICC, unpredictable output states, and potential device malfunction. Tie unused A-inputs to GND for LOW or VCC for HIGH based on desired default output state; unused OE inputs should be tied to VCC to maintain outputs in high-impedance mode.
Does SN74AHC367D support hot-swap operation?
SN74AHC367D supports limited hot-swap capability due to its ±2000 V HBM ESD rating and latch-up immunity exceeding 100 mA per JESD78 Class II. However, TI does not guarantee full hot-swap robustness without external protection (e.g., series resistors, TVS diodes). For true hot-swap systems, implement current-limiting and voltage-ramp circuits per TI's application report SLVA615.
