Product details
Overview
74HCT365N,652 from Nexperia is a hex non-inverting 3-state buffer/line driver with TTL-compatible inputs, 16-pin SO16 package, operating from 4.5 V to 5.5 V supply, −40 °C to +125 °C temperature range, and propagation delay of 38 ns max at VCC = 4.5 V - used for bus interfacing and signal isolation in industrial control backplanes.
For engineers reviewing the 74HCT365N,652 datasheet, 74HCT365N,652 pinout, 74HCT365N,652 application, or 74HCT365N,652 equivalent, key selection criteria include TTL-level input compatibility, dual active-low output enables (OE1/OE2), 6-channel non-inverting buffering with high-impedance outputs, and SO16 thermal performance up to +125 °C.
Technical Context
The 74HCT365N,652 implements six independent non-inverting buffer stages, each with dedicated input and output terminals, controlled by two shared active-low 3-state enable inputs (OE1 on Pin 1, OE2 on Pin 15). 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 ±6.0 mA at VCC = 4.5 V while maintaining VOL ≤ 0.4 V and VOH ≥ 3.7 V across −40 °C to +125 °C. Input clamping diodes allow safe interface to voltages exceeding VCC when used with current-limiting resistors, supporting mixed-voltage system design.
Key Specifications

| 15 (OE2) | Output enable 2 | Active-low control for buffers 4–6; decouples lower three outputs from upper three |
| 16 (VCC) | Positive supply | 4.5–5.5 V power rail; bypass capacitor (100 nF) required near pin for transient suppression |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | Accepts standard 5 V TTL voltage levels (VIH ≥ 2.0 V, VIL ≤ 0.8 V), eliminating need for level translators in legacy 5 V systems |
| Dual 3-state enables | OE1 controls outputs 1–3; OE2 controls outputs 4–6 - enables selective bus segment isolation in multi-peripheral designs |
| High-temperature operation | Specified from −40 °C to +125 °C - supports deployment in engine control units, motor drives, and industrial enclosures without derating |
| Low dynamic power | CPD = 40 pF per buffer - enables predictable dynamic power calculation (PD = CPD × VCC² × fi × N) for thermal management |
| ESD robustness | HBM > 2000 V, CDM > 1000 V - withstands handling and board assembly ESD events without protection circuitry overhead |
| Input clamp diodes | Integrated diodes allow safe interface to voltages > VCC when series current-limiting resistors are used - simplifies mixed-supply interconnect |
Applications
| Industrial Backplane Bus Driver | Legacy System Signal Isolation |
|---|---|
Use Scenario: Driving address/data lines across a 20 cm PCB backplane in a modular PLC rack with multiple I/O cards. IC Role / Device Role / Timing Role: Hex buffer isolates microcontroller GPIOs from capacitive bus loading and provides 3-state control for multi-master arbitration. Use Value: 38 ns max propagation delay ensures setup/hold timing compliance at 10 MHz bus rates; dual OE pins allow card-specific bus release without affecting adjacent slots. |
Use Scenario: Interfacing a modern ARM-based controller (3.3 V I/O) to legacy 5 V peripheral modules via level-shifted control lines. IC Role / Device Role / Timing Role: Acts as unidirectional level-tolerant buffer using input clamping diodes and series resistors - no external level shifter needed. Use Value: TTL-compatible inputs accept 5 V signals directly; outputs swing rail-to-rail at 4.5–5.5 V, ensuring reliable recognition by downstream 74LS/74ALS receivers. |
| Automotive Sensor Interface Hub | Test Equipment Signal Conditioning |
Use Scenario: Aggregating six analog sensor conditioning outputs (e.g., pressure, temperature, position) onto a shared diagnostic bus in an engine control module. IC Role / Device Role / Timing Role: Provides noise-immune signal buffering and enables/disables sensor data streams during calibration or fault recovery sequences. Use Value: −40 °C to +125 °C rating matches under-hood ambient; high noise immunity (CMOS architecture + 100 mA latch-up rating) prevents false triggers in EMI-heavy environments. |
Use Scenario: Routing digital stimulus signals from a pattern generator to multiple DUT inputs while preventing signal reflections and crosstalk. IC Role / Device Role / Timing Role: Functions as impedance-matched line driver with controlled transition times (5–12 ns) to minimize ringing on 50 Ω coaxial paths. Use Value: 6.0 mA drive strength sustains signal integrity over 1 m cables; disable time (53 ns max) enables precise timing window control during test vector sequencing. |
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 |
|---|---|---|---|
| 74HCT365PW,118 | TSSOP16 package (4.4 mm width); 0.65 mm lead pitch; 1.2 mm max height - 35 % smaller footprint than SO16 | Preferred for space-constrained PCBs; thermal resistance higher (8.5 mW/K derating above 91 °C vs. 12.4 mW/K for SO16) | Select when board area is critical and thermal load is moderate; verify reflow profile compatibility with fine-pitch leads |
| SN74HCT365N | Same SO16 package but Texas Instruments variant; VIH/VIL thresholds identical; propagation delay 35 ns max (VCC = 5 V, 25 °C) - slightly tighter typical spec | Valid for TI-centric BOMs; pinout and function identical; RoHS status and lot traceability differ per manufacturer | Choose for TI-design ecosystems or dual-sourcing requirements; confirm TI's +125 °C qualification scope matches Nexperia's |
Compared with 74HCT365N,652, the TSSOP variant saves board space but requires finer assembly control, while the TI version offers identical functionality with alternate supply-chain assurance - both retain the same TTL input compatibility, dual-OE architecture, and industrial temperature support.

FAQ
What is the maximum supply voltage for 74HCT365N,652?
The absolute maximum supply voltage for 74HCT365N,652 is +7.0 V, but the recommended operating range is strictly 4.5 V to 5.5 V. Operation outside this range may cause unreliable logic behavior or accelerated wear; sustained use above 5.5 V voids parametric guarantees including VOH/VOL and propagation delay.
Does 74HCT365N,652 support 3.3 V input signals?
No - 74HCT365N,652 has TTL-compatible inputs requiring VIH ≥ 2.0 V and VIL ≤ 0.8 V at VCC = 4.5–5.5 V. A 3.3 V logic HIGH may fall below the 2.0 V minimum VIH threshold under worst-case conditions (e.g., temperature, process variation), risking misreads. Use 74HC365 or level-shifting circuitry for 3.3 V systems.
Can both OE1 and OE2 be tied together in 74HCT365N,652?
Yes - OE1 (Pin 1) and OE2 (Pin 15) can be connected to a single control line to enable/disable all six outputs simultaneously. This configuration reduces GPIO usage and simplifies firmware control, though it forfeits independent gating of the two buffer groups (1–3 vs. 4–6) inherent to the device's dual-enable architecture.
What is the thermal derating behavior of 74HCT365N,652 in SO16 package?
In the SO16 (SOT109-1) package, 74HCT365N,652 total power dissipation (Ptot) derates linearly at 12.4 mW/K above +110 °C. At +125 °C ambient, Ptot is reduced by 186 mW from its 500 mW nominal rating - resulting in a maximum allowable dissipation of 314 mW for continuous operation within specification limits.
Is 74HCT365N,652 qualified for automotive applications?
74HCT365N,652 is specified for −40 °C to +125 °C operation and meets JESD7A/JESD8C standards, but Nexperia does not classify it as AEC-Q100 automotive-qualified. It may be used in non-safety-critical automotive subsystems (e.g., cabin control, diagnostics) subject to customer validation; for ASIL-B/C systems, AEC-Q100-qualified alternatives must be selected.
