Product details
Overview
M74HC365YRM13TR from STMicroelectronics is an automotive-grade hex non-inverting bus buffer with 3-state outputs, fabricated in silicon gate C2MOS technology. It operates from 2 V to 6 V, delivers 6 mA output drive (min), exhibits 10 ns typical propagation delay at 6 V, and supports -40 °C to +125 °C operation for engine control unit signal conditioning.
For engineers reviewing the M74HC365YRM13TR datasheet, M74HC365YRM13TR pinout, M74HC365YRM13TR application, or M74HC365YRM13TR equivalent, key selection criteria include dual enable logic (G1/G2), high noise immunity (28 % VCC min), SO16 automotive package qualification per AEC-Q100, and 3-state output timing behavior under load.
Technical Context
The device implements six independent non-inverting buffers, each enabled only when both G1 and G2 are low; all other input combinations force outputs into high-impedance state. Input protection includes ESD robustness (HBM 2 kV, CDM 1 kV) and transient voltage clamping.
Propagation delays are balanced (tPLH ≅ tPHL), output impedance is symmetrical (|IOH| = IOL ≥ 6 mA), and DC noise margins meet VIH ≥ 3.15 V / VIL ≤ 1.35 V at VCC = 4.5 V across full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2 V to 6 V - supports mixed-voltage system interfacing including 3.3 V and 5 V logic domains |
| tPD (typ) | 10 ns at VCC = 6 V - enables reliable timing in high-speed digital buses up to ~50 MHz |
| IOL / IOH (min) | 6 mA - sufficient to drive standard TTL loads or multiple CMOS inputs without fanout limitation |
| VIH / VIL | 3.15 V / 1.35 V at VCC = 4.5 V - ensures noise margin >1.1 V for robust operation in noisy automotive environments |
| ESD HBM | 2 kV - meets minimum requirement for handling during PCB assembly and field service |
| Operating Temp | -40 °C to +125 °C - qualified for under-hood automotive applications per AEC-Q100 Grade 1 |
| ICC (max) | 80 μA at TA = -55 °C to 125 °C - enables low-static-power designs in always-on vehicle subsystems |
Pinout & Package
SO16 package: 16-pin small outline integrated circuit, 3.9 mm body width, 1.27 mm pitch, gull-wing leads, RoHS-compliant ECOPACK®2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15 | G1, G2 | Dual active-low enable inputs - both must be low to activate all six buffers; prevents partial bus contention |
| 2, 4, 6, 10, 12, 14 | 1A–6A | Input terminals for six independent data channels - accept CMOS/TTL-compatible logic levels |
| 3, 5, 7, 9, 11, 13 | 1Y–6Y | Non-inverting buffered outputs - present high-impedance state when G1/G2 not both low |
| 8 | GND | Ground reference - decoupling capacitor placement critical for noise suppression in automotive harnesses |
| 16 | VCC | Positive supply - requires local 100 nF ceramic bypass capacitor per ST layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| High-speed propagation | 10 ns typical tPD at 6 V enables synchronization in CAN/LIN gateway timing-critical paths |
| Automotive qualification | AEC-Q100 Grade 1 qualification confirms reliability for engine control, transmission, and body electronics |
| Symmetrical drive strength | 6 mA sink/source capability ensures matched rise/fall times on bidirectional data lines |
| 3-state dual-enable logic | Independent control of all six buffers via shared G1/G2 reduces PCB routing complexity vs. discrete enables |
| Low quiescent current | 4 μA max ICC at 25 °C supports always-on modules such as battery monitoring IC interfaces |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex non-inverting 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC365QPWRQ1 | TI AEC-Q100 Grade 1 part; identical pinout and AC specs but higher ICC (100 μA max) and no CDM ESD rating specified | Validated for same automotive temp range but lacks CDM 1 kV specification required for certain Tier 1 ECU designs | Select when TI supply chain preference exists and CDM testing is not mandated by OEM spec |
| 74HC365D,653 | Nexperia industrial-grade SO16 part; same logic function but rated only to 125 °C (not AEC-Q100 qualified); lower ESD HBM (1.5 kV) | Approved for under-dash infotainment modules but excluded from powertrain or chassis control due to qualification gap | Choose for cost-sensitive non-safety-critical subsystems where full automotive qualification is unnecessary |
Compared with SN74HC365QPWRQ1 and 74HC365D,653, the M74HC365YRM13TR uniquely combines AEC-Q100 Grade 1 qualification, 1 kV CDM ESD rating, and 4 μA max ICC - making it the only option qualified for high-reliability engine management and brake-by-wire interface buffering.

FAQ
What is the maximum output current per channel for M74HC365YRM13TR?
The device guarantees minimum output current of ±6 mA per channel under DC conditions at VCC = 4.5 V and TA = 25 °C, with absolute maximum ratings allowing ±35 mA short-term. This drive strength supports direct connection to standard TTL loads or fanout to up to 10 CMOS inputs without external buffering.
Does M74HC365YRM13TR support hot insertion or live bus swapping?
Yes - its 3-state outputs, combined with input protection diodes and 2 kV HBM ESD rating, permit safe live insertion into powered bus systems. However, proper power sequencing (VCC applied before signals) and series current-limiting resistors on data lines are recommended per ST AN2012 guidelines to prevent latch-up during hot plug events.
How does the dual-enable architecture (G1/G2) improve system reliability?
The requirement that both G1 and G2 be low to enable outputs eliminates spurious activation from single-point faults like solder bridges or EMI-induced glitches on one enable line. This redundancy reduces risk of unintended bus contention in safety-critical automotive networks where deterministic state control is essential.
Is the SO16 package of M74HC365YRM13TR lead-free and RoHS compliant?
Yes - the SO16 package uses lead-free terminations and complies with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. It is also qualified to ECOPACK®2 standards, confirming halogen-free materials and reduced environmental impact without compromising thermal or mechanical performance.
