Product details
Overview
74HC367DB,112 from Nexperia is a hex non-inverting buffer/line driver with 3-state outputs, designed for bus interface and data routing in digital systems. It operates across 2.0 V to 6.0 V supply, delivers propagation delay as low as 8 ns at VCC = 6.0 V, supports -40 °C to +125 °C ambient range, and features TTL-compatible input thresholds when used as 74HCT367 variant - deployed in industrial control backplanes and microcontroller I/O expansion.
For engineers reviewing the 74HC367DB,112 datasheet, 74HC367DB,112 pinout, 74HC367DB,112 application, or 74HC367DB,112 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 static drive capability (±35 mA per output).
Technical Context
This device implements six independent non-inverting buffers, each with active-low 3-state enable control (1OE, 2OE) allowing bidirectional bus management. All inputs include clamp diodes enabling safe interfacing to voltages exceeding VCC via current-limiting resistors.
It conforms to JEDEC JESD7A (2.0 V–6.0 V) and JESD8C (2.7 V–3.6 V) standards, supports HBM ESD >2000 V and CDM >1000 V, and guarantees latch-up immunity >100 mA per JESD78 Class II Level B - ensuring robust operation in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - enables direct interface with 3.3 V and 5 V logic domains without level shifters |
| Propagation Delay (tpd) | 8 ns max at VCC = 6.0 V, CL = 50 pF - ensures sub-10 ns timing margin for 50 MHz bus clocking |
| 3-State Enable Time (ten) | 13 ns max at VCC = 6.0 V - critical for fast bus arbitration and dynamic load switching |
| Output Drive Current | ±35 mA per output - sufficient to drive 50 pF loads with <15 ns transition time (tt) |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive modules and industrial PLCs |
| Input Clamp Diodes | Integrated - permits safe overvoltage input protection up to VCC + 0.5 V using external series resistors |
| Power Dissipation Capacitance | 30 pF per buffer - enables accurate dynamic power estimation (PD = CPD × VCC² × fi × N) |
Pinout & Package
74HC367DB,112 is packaged in SO16 (SOT109-1): plastic small outline, 16-pin, 3.9 mm body width, 1.27 mm pitch, with standard JEDEC MS-012 footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15 | 1OE, 2OE | Active-low 3-state enable inputs - each controls three outputs; LOW enables, HIGH forces high-impedance |
| 2, 4, 6, 10, 12, 14 | 1A–6A | Buffer input pins - CMOS-level compatible; clamp diodes allow overvoltage tolerance |
| 3, 5, 7, 9, 11, 13 | 1Y–6Y | Non-inverting buffered outputs - 3-state capable; drive ±35 mA into resistive or capacitive loads |
| 8 | GND | Ground reference - must be connected to system 0 V plane with low-inductance path for noise immunity |
| 16 | VCC | Positive supply - decoupling capacitor (100 nF ceramic) required within 5 mm of pin for stable operation |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range | 2.0 V–6.0 V operation - eliminates need for separate voltage rails in mixed-supply systems |
| 3-state bus control | Dual enable inputs (1OE/2OE) partition outputs into two groups of three - simplifies multi-master bus arbitration |
| High noise immunity | CMOS input structure with >40 % VCC noise margin at 5 V - resists EFT and radiated interference |
| Latch-up robustness | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during transient overcurrent |
| ESD protection | HBM >2000 V, CDM >1000 V - meets IEC 61000-4-2 Level 4 for system-level ESD resilience |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex buffer/line driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC367D,112 | Same die, SO16 package without 'B' suffix - identical electrical specs and pinout | No functional difference; 'B' denotes tape-and-reel packaging variant per Nexperia ordering convention | Select 74HC367D,112 only if bulk or tube packaging is required; otherwise 74HC367DB,112 preferred for SMT automation. |
| SN74LVC1G34DBVR | Single-channel LVC variant - 1.65 V–5.5 V supply, 3.7 ns tpd, no 3-state output | Not a drop-in replacement - requires six discrete units and external enable logic for equivalent functionality | Choose only for ultra-low-power, space-constrained designs where full hex functionality is unnecessary. |
Compared with 74HC367DB,112, the 74HC367D,112 offers identical performance in alternate packaging, while SN74LVC1G34DBVR trades integration density and 3-state control for lower voltage operation and single-gate flexibility - making it unsuitable for bus interface but viable for point-to-point signal conditioning.

FAQ
What is the maximum operating supply voltage for 74HC367DB,112?
The absolute maximum supply voltage for 74HC367DB,112 is +7.0 V, but the recommended operating range is 2.0 V to 6.0 V per datasheet Table 5. Operation above 6.0 V risks permanent damage and violates JEDEC JESD7A compliance - sustained use at 7.0 V is prohibited even for transient conditions.
Does 74HC367DB,112 support TTL-level inputs?
No - 74HC367DB,112 is the CMOS-input variant; its input thresholds scale with VCC (VIH ≥ 0.7×VCC, VIL ≤ 0.3×VCC). For TTL compatibility, use 74HCT367DB,112 instead, which specifies VIH = 2.0 V min and VIL = 0.8 V max at VCC = 4.5 V–5.5 V.
How many output enable inputs does 74HC367DB,112 have, and how are they assigned?
74HC367DB,112 has two active-low output enable inputs: 1OE (pin 1) controls outputs 1Y, 2Y, and 3Y; 2OE (pin 15) controls outputs 4Y, 5Y, and 6Y. This dual-enable architecture allows independent gating of two 3-bit bus segments - essential for multi-master arbitration schemes.
What is the thermal derating behavior of 74HC367DB,112 in SO16 package?
In the SO16 (SOT109-1) package, 74HC367DB,112 total power dissipation (Ptot) derates linearly at 12.4 mW/K above +110 °C ambient. At +125 °C, maximum allowable Ptot drops to 313 mW from the rated 500 mW - requiring careful thermal design in sealed enclosures or high-ambient environments.
Can 74HC367DB,112 be used in automotive applications?
Yes - 74HC367DB,112 is qualified for -40 °C to +125 °C operation and meets JESD78 latch-up and JEDEC ESD requirements, making it suitable for non-safety-critical automotive applications like body control modules and infotainment interfaces. It is not AEC-Q100 qualified, so safety-critical systems require additional validation.
