Product details
Overview
74HCT367N,652 from Nexperia is a hex non-inverting 3-state buffer/line driver with TTL-compatible inputs, operating from 4.5 V to 5.5 V supply, delivering ±6 mA output drive at VCC = 4.5 V, and supporting industrial temperature range (−40 °C to +125 °C) in SO16 package - used for bus isolation and signal routing in digital control systems.
For engineers reviewing the 74HCT367N,652 datasheet, 74HCT367N,652 pinout, 74HCT367N,652 application, or 74HCT367N,652 equivalent, key selection considerations include TTL-level input compatibility, 3-state bus contention avoidance, propagation delay ≤25 ns (VCC = 4.5 V), disable time ≤53 ns, and SO16 thermal performance up to 125 °C ambient.
Technical Context
The 74HCT367N,652 implements six independent non-inverting buffers, each with active-low 3-state enable (1OE, 2OE) controlling three outputs per group. Its TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V) ensure direct interfacing with legacy 5 V logic families without level shifting.
Each output drives ±6 mA while maintaining VOL ≤ 0.26 V and VOH ≥ 3.7 V under load, and features input clamp diodes enabling safe interface to voltages exceeding VCC when used with current-limiting resistors. The device complies with JEDEC JESD7A and JESD8C standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL and CMOS systems without regulation overhead |
| Input Logic Type | TTL-level - accepts 0.8 V/2.0 V thresholds, eliminating need for external level translators when driving from 5 V microcontrollers or FPGAs |
| Output Drive Strength | ±6 mA at VCC = 4.5 V - sufficient to drive multiple 74-series loads or 50 pF PCB traces without signal degradation |
| Propagation Delay | ≤25 ns (VCC = 4.5 V, CL = 50 pF) - supports reliable operation in 20 MHz bus environments with timing margin |
| 3-State Disable Time | ≤53 ns (VCC = 4.5 V) - enables fast bus turnaround in shared-data applications like memory-mapped I/O or peripheral multiplexing |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood industrial control, motor drives, and power supply monitoring circuits |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - provides robust handling during board assembly and field service without additional protection circuitry |
Pinout & Package
74HCT367N,652 uses the SOT109-1 (SO16) plastic small outline package: 16-pin, 3.9 mm body width, 1.27 mm pitch, with standard gull-wing leads suitable for reflow soldering and automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15 | 1OE, 2OE | Active-low 3-state enable inputs - each controls three outputs; LOW enables buffer, HIGH places outputs in high-impedance state |
| 2, 4, 6, 10, 12, 14 | 1A–6A | Data inputs - six independent logic inputs accepting TTL-level signals directly |
| 3, 5, 7, 9, 11, 13 | 1Y–6Y | Buffered outputs - non-inverting, 3-state, capable of sourcing/sinking ±6 mA |
| 8 | GND | Ground reference - must be connected to system 0 V plane with low-inductance path for noise immunity |
| 16 | VCC | Positive supply - requires local 100 nF ceramic decoupling capacitor placed within 5 mm of pin |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V - eliminates level-shifter components in mixed-logic designs |
| 3-state bus interface | Two independent enable inputs (1OE, 2OE) each controlling three outputs - enables clean arbitration on shared data buses |
| High noise immunity | CMOS design with hysteresis-free inputs and >40 % noise margin at VCC = 5 V - resists EMI in industrial motor-control environments |
| Input clamp diodes | Integrated diodes allow safe connection to voltages up to VCC + 0.5 V using series current-limiting resistors - simplifies overvoltage-tolerant input design |
| Wide temperature operation | Specified from −40 °C to +125 °C - supports deployment in automotive engine bays and industrial PLC backplanes without derating |
Applications
| Industrial PLC I/O Expansion | Legacy Microcontroller Bus Interface |

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 |
|---|---|---|---|
| 74HCT367D,652 | Same electrical specs but in TSSOP16 (SOT403-1) package - 4.4 mm body width, 0.65 mm pitch | Requires PCB redesign for smaller footprint and finer pitch; better thermal resistance at high density | Select for space-constrained boards where SO16 layout is unavailable; verify reflow profile for TSSOP |
| SN74HCT367N | TI variant with identical logic function, TTL inputs, and 4.5–5.5 V operation; minor differences in ICC max (160 μA vs 160 μA) and tpd (25 ns vs 25 ns) | Pinout and timing match exactly; qualifies for use in existing 74HCT367N,652 layouts with no firmware change | Use when dual-sourcing required across Nexperia and TI supply chains; verify TI's -40 °C to +125 °C qualification documentation |
Compared with 74HCT367N,652, the TSSOP variant offers higher board density but demands tighter assembly control, while the TI SN74HCT367N delivers identical functional behavior with second-source assurance - both require validation of thermal performance under sustained 125 °C ambient conditions.

FAQ
What logic family does the 74HCT367N,652 belong to, and how does it differ from 74HC variants?
The 74HCT367N,652 belongs to the 74HCT (High-speed CMOS with TTL input thresholds) family. Unlike the 74HC367 which requires CMOS-level inputs (VIH ≈ 0.7×VCC), the 74HCT367N,652 accepts standard TTL input voltages (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), enabling direct connection to legacy 5 V TTL outputs without level translation. Its internal structure remains CMOS, preserving low power and high noise immunity.
Does the 74HCT367N,652 support operation at 3.3 V supply voltage?
No, the 74HCT367N,652 is not specified for 3.3 V operation. Its recommended supply range is strictly 4.5 V to 5.5 V, with input thresholds fixed for TTL compatibility. At 3.3 V, VIH (2.0 V min) would exceed 60 % of VCC, violating input margin requirements and risking unreliable logic recognition. For 3.3 V systems, use 74LVC367 or 74ALVC367 instead.
How many independent 3-state groups does the 74HCT367N,652 provide, and how are they configured?
The 74HCT367N,652 provides two independent 3-state groups: 1OE (pin 1) controls outputs 1Y, 2Y, and 3Y (pins 3, 5, 7), while 2OE (pin 15) controls outputs 4Y, 5Y, and 6Y (pins 9, 11, 13). Each group can be enabled or disabled separately, allowing partial bus isolation - for example, holding sensor data lines active while tri-stating actuator control lines during diagnostics.
What is the maximum capacitive load the 74HCT367N,652 can drive while maintaining specified timing?
The 74HCT367N,652 is characterized for CL = 50 pF in its dynamic specifications (tpd ≤25 ns, tdis ≤53 ns at VCC = 4.5 V). While it can physically drive heavier loads, timing degrades linearly with capacitance - e.g., at CL = 100 pF, propagation delay increases by ~30 %. For reliable 20 MHz bus operation, keep total load (including trace + input capacitance) ≤50 pF; add series termination if exceeding this limit.
Is the 74HCT367N,652 suitable for automotive applications?
The 74HCT367N,652 is not automotive-qualified. Though it operates from −40 °C to +125 °C, it lacks AEC-Q100 qualification, automotive-grade screening, and failure-in-time (FIT) rate reporting. Nexperia explicitly states non-automotive qualified products are unsuitable for safety-critical automotive use. For automotive designs, select AEC-Q100 qualified equivalents such as 74HCT367-Q100 in SO16.
