Product details
Overview
74LCX07YMTR from STMicroelectronics is an automotive-grade, low-voltage CMOS hex buffer with open-drain outputs and 5 V tolerant inputs, operating from 2.0 V to 3.6 V supply. It delivers 5.2 ns max propagation delay at 3 V, ±24 mA output drive, and symmetrical output impedance-enabling direct interface between 3.3 V logic and legacy 5 V buses in engine control units and infotainment gateways.
For engineers reviewing the 74LCX07YMTR datasheet, 74LCX07YMTR pinout, 74LCX07YMTR application, or 74LCX07YMTR equivalent, this device is selected for high-speed, low-power level translation in noise-sensitive automotive subsystems where latch-up immunity (>500 mA), AEC-Q100 qualification, and ESD robustness (2 kV HBM) are mandatory.
Technical Context
The 74LCX07YMTR implements six independent open-drain buffers using sub-micron C2MOS technology, with input protection diodes enabling safe 5 V signal injection while powered from 3.3 V. Its internal two-stage buffer design ensures high noise immunity and stable output transitions under varying load conditions.
All six channels share identical electrical behavior: truth table defines low-level output (L → L) and high-impedance state (H → Z); no internal pull-up exists-external pull-up required per channel. Input leakage is ±5 μA, and power-down protection prevents current flow when VCC = 0 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Operating Range | 2.0 V to 3.6 V - supports standard 3.3 V rail with 10% tolerance margin; not compatible with 5 V supply. |
| tPD (Max) | 5.2 ns at VCC = 3.0–3.6 V, CL = 50 pF - matches AC/ACT speed at half the voltage, enabling drop-in replacement in timing-critical data paths. |
| IOL / IOH | ±24 mA min at VCC = 3.0–3.6 V - drives standard PCI bus loads without external buffering; symmetrical sourcing/sinking enables bidirectional signaling. |
| Input Voltage Tolerance | 0 V to 5.5 V - allows direct connection to 5 V microcontrollers, sensors, or legacy peripherals without level-shifter circuitry. |
| ESD Rating (HBM) | 2000 V - exceeds automotive requirement for human-body model; eliminates need for external TVS on I/O lines in ECU modules. |
| Latch-up Immunity | >500 mA per JESD17 - withstands transient overcurrent events common in vehicle battery line transients and load-dump scenarios. |
Pinout & Package
74LCX07YMTR is housed in a 14-pin SOIC (SO-14) package, 8.55–8.75 mm body length, 3.8–4.0 mm width, 1.35–1.75 mm height, with 1.27 mm pitch. Automotive-grade variant qualified per AEC-Q100 Grade 2 (-40 °C to +105 °C ambient).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 (1A–6A) | Data Inputs | CMOS-compatible inputs accepting 0–5.5 V; internally clamped to VCC and GND; tolerate 5 V even when VCC = 0 V. |
| 2, 4, 6, 8, 10, 12 (1Y–6Y) | Open-Drain Outputs | No internal pull-up; require external pull-up resistor to define HIGH level; sink up to 24 mA per channel. |
| 7 | GND | Ground reference for all I/O and internal logic; must be connected before VCC during power sequencing. |
| 14 | VCC | Primary supply pin (2.0–3.6 V); powers internal logic and output stage; decoupling capacitor (100 nF) required within 5 mm. |
Key Features
| Feature | Design Value |
|---|---|
| 5 V tolerant inputs | Enables mixed-voltage system integration without discrete level shifters-reduces BOM count and PCB area in ADAS sensor hubs. |
| Open-drain outputs with 24 mA sink | Supports wired-AND bus architectures and I²C-compatible signaling; drives standard LED indicators or optocoupler inputs directly. |
| Power-down protection | Prevents back-driving and current leakage when VCC = 0 V-critical for hot-swap capability in telematics gateway modules. |
| AEC-Q100 qualified (Grade 2) | Validated for automotive use including thermal cycling, humidity testing, and vibration-meets OEM requirements for powertrain ECUs. |

FAQ
Can 74LCX07YMTR operate with VCC = 5 V?
No. The absolute maximum VCC is +7.0 V, but recommended operating range is strictly 2.0 V to 3.6 V. Applying 5 V to VCC violates specification and risks permanent damage. Inputs remain 5 V tolerant regardless of VCC setting, but supply must stay within rated range.
Is an external pull-up resistor required for each output?
Yes. As an open-drain device, 74LCX07YMTR cannot source current. Each Y output requires an external pull-up resistor to a defined voltage rail (e.g., 3.3 V or 5 V). Typical values range from 1 kΩ to 10 kΩ depending on rise time and bus capacitance.
Does 74LCX07YMTR support hot insertion when VCC = 0 V?
Yes. Power-down protection ensures inputs and outputs remain high-impedance with no current flow when VCC is unpowered. Input diodes clamp to GND and VCC rails, preventing back-powering or latch-up-validated per JESD78 and AEC-Q100 stress tests.
What is the maximum capacitive load per output?
Electrical characteristics are specified with CL = 50 pF. While not explicitly limited, output drive degrades above ~100 pF due to increased rise time. For reliable 5.2 ns tPD performance, total load (including trace, connector, and input capacitance) should remain ≤50 pF per channel.
