Product details
Overview
74HCT365PW-Q100 from Nexperia is an automotive-grade hex non-inverting buffer/line driver with 3-state outputs, controlled by two active-low output enable inputs (OE1, OE2). It operates from 4.5 V to 5.5 V, delivers ±6.0 mA output drive at VCC = 4.5 V, and supports -40 °C to +125 °C ambient temperature - qualified per AEC-Q100 Grade 1. It is used in automotive body control modules for bidirectional signal buffering between microcontrollers and high-impedance sensor or actuator interfaces.
For engineers reviewing the 74HCT365PW-Q100 datasheet, 74HCT365PW-Q100 pinout, 74HCT365PW-Q100 application, or 74HCT365PW-Q100 equivalent, this page provides verified functional architecture, TTL-compatible input thresholds, 3-state timing specs (enable/disable times ≤ 53 ns at +125 °C), package-specific thermal derating, and validated automotive alternatives with documented voltage-level and timing differences.
Technical Context
This device implements six independent non-inverting buffers, each with output disable capability via shared OE1/OE2 control logic. All inputs feature clamp diodes enabling safe interfacing to voltages exceeding VCC when current-limiting resistors are used.
It uses standard CMOS silicon with TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5 V), ensuring compatibility with legacy 5 V logic families. Output transition times are specified down to 5 ns (typ) at VCC = 4.5 V and CL = 15 pF, supporting medium-speed bus isolation in engine control units and ADAS domain controllers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 5.5 V - matches standard automotive 5 V rail; excludes 3.3 V operation unlike HC variant |
| Input Logic Type | TTL-compatible - VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 4.5 V; enables direct connection to 5 V MCU GPIOs |
| Output Drive Strength | ±6.0 mA at VCC = 4.5 V - sufficient to drive 50 pF loads with <38 ns propagation delay across full temp range |
| 3-State Enable/Disable Time | ten ≤ 53 ns, tdis ≤ 53 ns at +125 °C - ensures clean bus arbitration in multiplexed CAN/LIN peripheral interfaces |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1; supports under-hood ECU placement |
| ESD Robustness | HBM > 2000 V, CDM > 1000 V - meets automotive system-level ESD immunity requirements without external protection |
| Power Dissipation | ICC ≤ 160 μA at VCC = 5.5 V, +125 °C - enables low-quiescent-current design in always-on vehicle networks |
Pinout & Package
TSSOP16 plastic thin shrink small outline package (SOT403-1); 16 leads; body width 4.4 mm; 0.65 mm pitch; exposed pad not present; RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15 | OE1, OE2 | Active-low output enable inputs - both must be LOW to activate all six buffers; independent control not supported |
| 2, 4, 6, 10, 12, 14 | 1A–6A | Data inputs - non-inverting; accept TTL-level signals; include input clamp diodes for overvoltage tolerance |
| 3, 5, 7, 9, 11, 13 | 1Y–6Y | Data outputs - 3-state; high-impedance when either OE1 or OE2 is HIGH; drive ±6 mA at VCC = 4.5 V |
| 8 | GND | Ground reference - must be connected to system 0 V plane; no separate ground pin for each buffer |
| 16 | VCC | Positive supply - decoupling capacitor (100 nF ceramic) required within 5 mm of pin for stable switching |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C with lifetime reliability testing per JEDEC JESD47 |
| TTL-compatible input thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 4.5 V - eliminates need for level shifters when interfacing with legacy 5 V MCUs |
| Input clamp diodes | Enables safe interface to signals up to VCC + 0.5 V using external current-limiting resistors - protects against battery dump transients |
| Low dynamic power dissipation | CPD = 40 pF per buffer - limits switching power to <1.0 mW per channel at 1 MHz, 5 V, 50 pF load |
| High noise immunity | Typical noise margin > 1.2 V at VCC = 4.5 V - suppresses coupling from ignition systems and motor drivers in chassis applications |
Applications
| Automotive Body Control Module (BCM) | Engine Control Unit (ECU) Sensor Interface |
|---|---|
|
Use Scenario: Isolating microcontroller GPIOs from high-impedance door lock actuators and mirror position sensors. IC Role / Device Role / Timing Role: Non-inverting buffer with 3-state control enables time-multiplexed access to shared LIN bus lines while preventing back-driving.

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 |
|---|---|---|---|
| 74HCT365D-Q100 | SO16 package (SOT109-1); 3.9 mm body width; higher thermal resistance (12.4 mW/K derating above 110 °C) | Better suited for through-hole prototyping or legacy PCBs with SOIC footprints; lower pin density than TSSOP | Select when board space permits larger footprint or when manual soldering is required |
| SN74HCT365QPWRQ1 | Texas Instruments part; identical function and AEC-Q100 Grade 1 rating; VIH/VIL thresholds match within 0.1 V; tpd max 35 ns at +125 °C vs 38 ns | Approved for use in GM, Ford, and Stellantis platforms; TI's Q1 suffix denotes automotive qualification per same standard | Choose for dual-sourcing in Tier-1 programs requiring second-source validation per OEM PPAP |
Compared with 74HCT365PW-Q100, the SO16 variant trades board area for easier rework and higher thermal mass, while the TI alternative offers identical functionality with tighter timing tolerances and broader OEM acceptance - both require no schematic or layout changes beyond footprint adaptation.

FAQ
Is 74HCT365PW-Q100 pin-compatible with 74HC365PW-Q100?
Yes - both share identical TSSOP16 pinout (SOT403-1), but differ electrically: 74HCT365PW-Q100 accepts TTL-level inputs (VIH ≥ 2.0 V), while 74HC365PW-Q100 requires CMOS-level inputs (VIH ≥ 3.15 V at VCC = 4.5 V). Swapping requires verification of driving source logic family.
What is the maximum capacitive load this device can drive reliably?
Per datasheet Table 8, it drives 50 pF loads with guaranteed tpd ≤ 38 ns at +125 °C and VCC = 4.5 V. For 100 pF loads, propagation delay increases to ~55 ns (extrapolated from CL vs. tpd curves), remaining within functional timing budgets for most automotive control buses.
Can OE1 and OE2 be tied together for simplified control?
Yes - OE1 and OE2 are logically OR'd internally; tying them together to a single microcontroller GPIO reduces control lines by 50%. This configuration is explicitly supported in the functional table and used in reference designs for BCM signal routing.
Does this device support partial power-down mode with VCC = 0 V?
No - the datasheet specifies absolute maximum ratings only; no guaranteed behavior is defined for VCC = 0 V with inputs driven. Input clamp diodes may conduct if VI exceeds GND −0.5 V or VCC + 0.5 V, risking latch-up or damage without current limiting.
