Product details
Overview
74HCT365D-Q100,118 from Nexperia is an automotive-qualified hex non-inverting buffer/line driver with dual 3-state enable inputs (OE1, OE2), TTL-compatible input thresholds, 16-pin SO16 package, ±7.8 mA output drive at 4.5 V, and operation from −40 °C to +125 °C - used for bidirectional bus interfacing in engine control units and body electronics.
For engineers reviewing the 74HCT365D-Q100,118 datasheet, 74HCT365D-Q100,118 pinout, 74HCT365D-Q100,118 application, or 74HCT365D-Q100,118 equivalent, key selection criteria include TTL-level input compatibility, dual independent 3-state control, SO16 thermal performance up to 125 °C ambient, and AEC-Q100 Grade 1 qualification for under-hood automotive use.
Technical Context
This device implements six independent non-inverting buffers, each with output enable controlled by either OE1 (pins 1 & 15) - enabling selective activation of odd- or even-numbered channels. The dual-OE architecture allows partitioned bus driving without external logic.
Input clamping diodes permit safe interfacing to voltages exceeding VCC when current-limiting resistors are used. Output stages are designed for rail-to-rail swing with guaranteed VOH ≥ 3.98 V and VOL ≤ 0.26 V at 6 mA load and VCC = 4.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 5.5 V - supports standard 5 V automotive power rails with margin for ripple and drop. |
| Input Logic Type | TTL-level compatible - VIH = 2.0 V min, VIL = 0.8 V max - interfaces directly with legacy 5 V microcontrollers and logic families. |
| Output Drive Strength | ±6.0 mA at VCC = 4.5 V - sufficient to drive 50 pF loads with <25 ns propagation delay across full temperature range. |
| Propagation Delay | 14–38 ns (typ–max) from input to output at VCC = 4.5 V - enables reliable timing in 20 MHz digital control buses. |
| 3-State Enable Timing | Enable/disable times ≤ 53 ns max at VCC = 4.5 V - ensures clean bus arbitration without contention during state transitions. |
| AEC-Q100 Qualification | Grade 1 (−40 °C to +125 °C) - qualified for powertrain, chassis, and ADAS modules per automotive reliability requirements. |
| ESD Robustness | HBM >2000 V, CDM >1000 V - withstands handling and board-level ESD events in manufacturing and service environments. |
Pinout & Package
Package: SO16 plastic small outline package (SOT109-1), 3.9 mm body width, 1.27 mm lead pitch, rated for reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15 | OE1, OE2 | Active-LOW dual output enable inputs - independently disable odd (1Y,3Y,5Y) or even (2Y,4Y,6Y) outputs. |
| 2, 4, 6, 10, 12, 14 | 1A–6A | Non-inverting data inputs - accept TTL-level signals; include clamp diodes for overvoltage tolerance. |
| 3, 5, 7, 9, 11, 13 | 1Y–6Y | Buffered non-inverting outputs - deliver rail-aligned logic levels with 3-state capability when OE is HIGH. |
| 8 | GND | Ground reference - must be low-inductance connection to minimize switching noise coupling. |
| 16 | VCC | Positive supply - decoupling capacitor (100 nF ceramic) required within 10 mm of pin for stable operation. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 3-state control | OE1 and OE2 allow grouped channel enable/disable - eliminates need for external gating logic in multiplexed bus systems. |
| TTL-compatible input thresholds | VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V - ensures interoperability with legacy 5 V MCUs and peripheral ICs. |
| Rail-to-rail CMOS output drive | VOH ≥ 3.98 V and VOL ≤ 0.26 V at 6 mA load - maintains noise margin >0.7 V in noisy automotive environments. |
| Input clamp diodes | Enable safe interface to signals up to VCC + 0.5 V using series current-limiting resistors - simplifies level-shifting in mixed-voltage subsystems. |
| AEC-Q100 Grade 1 qualification | Validated for −40 °C to +125 °C operation with latch-up immunity >100 mA - meets functional safety requirements for ASIL-B systems. |
Applications
| Engine Control Unit (ECU) Signal Conditioning | Body Control Module (BCM) I/O Expansion |

Use Scenario: Isolating and buffering sensor analog-to-digital converter (ADC) reference signals and digital status lines between MCU and high-noise power stages. IC Role / Device Role / Timing Role: Non-inverting buffer with 3-state isolation prevents back-driving during MCU reset or sleep modes. Use Value: Dual OE inputs allow synchronized release of ADC clock and data lines while holding other peripherals in high-Z - eliminating bus contention during mode transitions. |
Use Scenario: Driving multiple LED indicators, relay drivers, and LIN transceiver enable lines from a single 8-bit MCU port. IC Role / Device Role / Timing Role: Hex line driver providing fan-out amplification and voltage-level translation from MCU GPIO to 5 V loads. Use Value: 6.0 mA output drive sustains 5 V logic levels into 1 kΩ pull-ups - enabling direct control of optocouplers and discrete FET gates without external transistors. |
| Advanced Driver Assistance Systems (ADAS) Camera Interface | Automotive Infotainment Display Bus |
|
Use Scenario: Level-shifting and buffering parallel pixel clock and sync signals between image sensor and SoC video processor. IC Role / Device Role / Timing Role: Low-skew buffer preserving edge integrity on high-speed timing signals (e.g., PCLK, HSYNC). Use Value: 14 ns typical propagation delay and <15 ns transition time at 4.5 V ensure <1 ns inter-channel skew - critical for pixel alignment in multi-sensor fusion. |
Use Scenario: Isolating display controller data bus from touch controller and backlight driver circuits to reduce crosstalk. IC Role / Device Role / Timing Role: 3-state bus buffer enabling time-multiplexed access to shared 8-bit parallel interface. Use Value: Independent OE1/OE2 control allows interleaved read/write cycles between display and touch controllers - doubling effective bus bandwidth without added arbitration logic. |
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 |
|---|---|---|---|
| 74HCT365PW-Q100 | TSSOP16 package (SOT403-1), 4.4 mm body width, 0.65 mm pitch - smaller footprint but lower thermal mass and derated Ptot above 91 °C. | Better suited for space-constrained PCBs where board area is prioritized over thermal headroom in high-power modules. | Select when layout density outweighs sustained high-temperature operation; verify thermal relief via copper pour and airflow. |
| SN74HCT365QPWRQ1 | Texas Instruments variant; identical logic function and AEC-Q100 Grade 1 rating, but different pinout (OE1/OE2 on pins 1/15 vs TI's 1/16) and tighter VOH/VOL specs (≥4.1 V / ≤0.25 V @6 mA). | Drop-in replacement only with board redesign; preferred where higher noise margin or TI ecosystem support is required. | Choose only if existing design uses TI's footprint or requires TI-specific qualification documentation for OEM compliance. |
Compared with 74HCT365PW-Q100, the 74HCT365D-Q100,118 offers superior thermal dissipation in SO16 for continuous 125 °C operation; versus SN74HCT365QPWRQ1, it provides pin-compatible fit with Nexperia's validated automotive supply chain and broader voltage margin at VCC = 4.5 V.

FAQ
What is the maximum operating temperature for 74HCT365D-Q100,118?
The device is qualified per AEC-Q100 Grade 1 for continuous operation from −40 °C to +125 °C ambient. Maximum junction temperature is 150 °C, with SO16 package derating starting at 110 °C at 12.4 mW/K. Thermal design must maintain θJA < 50 K/W for full-rated performance.
Can 74HCT365D-Q100,118 interface directly with 3.3 V logic inputs?
No - its TTL-compatible inputs require VIH ≥ 2.0 V, but VIL ≤ 0.8 V at VCC = 4.5–5.5 V. A 3.3 V system outputting 2.4 V HIGH may not reliably register as HIGH; level-shifting or a 74LVC365 variant is recommended for mixed-voltage designs.
How does dual OE control improve system reliability?
OE1 controls outputs 1Y, 3Y, 5Y; OE2 controls 2Y, 4Y, 6Y. This allows independent disabling of signal groups - e.g., isolating sensor inputs during MCU reset while keeping communication lines active - preventing bus contention and latch-up in fault recovery sequences.
Is there a lead-free and RoHS-compliant version?
Yes - 74HCT365D-Q100,118 is manufactured in full compliance with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The SO16 package uses matte tin lead finish with no lead content exceeding 0.1 wt%.
