Product details
Overview
74HC4050D-Q100 from Nexperia is an automotive-grade hex non-inverting level shifter with overvoltage-tolerant inputs up to 15 V, operating from 2.0 V to 6.0 V supply, delivering 6 independent HIGH-to-LOW logic level translation channels for interfacing 5 V/15 V signal sources with 3.3 V or lower logic systems in engine control units and ADAS sensor hubs.
For engineers reviewing the 74HC4050D-Q100 datasheet, 74HC4050D-Q100 pinout, 74HC4050D-Q100 application, or 74HC4050D-Q100 equivalent, key selection criteria include input overvoltage tolerance (15 V), AEC-Q100 Grade 1 qualification (-40 °C to +125 °C), propagation delay (7 ns typical at VCC = 6.0 V), output drive capability (±5.2 mA), and SO16 package compatibility with legacy PCB footprints.
Technical Context
This device implements six independent CMOS buffer stages, each accepting high-voltage inputs (up to 15 V) while powered from a lower VCC rail (2.0–6.0 V), enabling robust bidirectional voltage domain bridging without external biasing or pull-up networks. Each channel operates as a true non-inverting level translator with no internal feedback or latching behavior.
Input protection includes polysilicon clamping resistors and diode structures rated for ±20 mA clamping current and 15 V absolute maximum input voltage, while output stages meet ±5.2 mA sink/source capability at VCC = 6.0 V with VOL ≤ 0.26 V and VOH ≥ 5.48 V under load - ensuring TTL- and CMOS-compatible logic thresholds across temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.0 V to 6.0 V - supports mixed-rail systems including 3.3 V microcontrollers interfacing with 5 V or 12 V sensors. |
| Input Voltage Range | 0 V to 15 V - enables direct connection to automotive battery-sensed signals without external attenuation or voltage dividers. |
| Propagation Delay | 7 ns (typical) at VCC = 6.0 V, CL = 50 pF - ensures timing-critical communication between ECUs and CAN/LIN transceivers remains within setup/hold windows. |
| Output Drive | ±5.2 mA at VCC = 6.0 V - sufficient to drive multiple 74HC inputs or small capacitive loads (< 50 pF) without signal degradation. |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive applications including powertrain and chassis modules. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - withstands handling and assembly stresses in automotive manufacturing environments. |
| Input Leakage | ±0.5 μA max at VI = 15 V - prevents unintended current paths when interfacing high-impedance analog or wake-up circuits. |
Pinout & Package
74HC4050D-Q100 is housed in a plastic small outline package (SO16), SOT109-1, with 16 leads and 3.9 mm body width. Pin 1 is marked by a notch or dot; pins are numbered counter-clockwise from pin 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Positive supply rail - must be decoupled locally with 100 nF ceramic capacitor to suppress switching noise. |
| 2 | 1Y | Channel 1 output - drives downstream 3.3 V logic; compatible with 74HC, 74LVC, and ARM GPIO inputs. |
| 3 | 1A | Channel 1 input - accepts 5 V or 12 V digital signals while VCC = 3.3 V, enabling passive level shifting. |
| 4 | 2Y | Channel 2 output - electrically isolated from other outputs; suitable for driving separate subsystem clocks or enable lines. |
| 5 | 2A | Channel 2 input - independently tolerant to 15 V; no shared input impedance or crosstalk with adjacent channels. |
| 6 | 3Y | Channel 3 output - low-capacitance (3.5 pF) node minimizes signal rise/fall time degradation in high-speed interfaces. |
| 7 | 3A | Channel 3 input - clamped via internal diodes to VCC/GND; safe for hot-plug or transient-prone sensor lines. |
| 8 | GND | Ground reference - must be connected to system ground plane with low-inductance path to ensure noise immunity. |
| 9 | 4Y | Channel 4 output - matches VOH/VOL specs across full temperature range, supporting reliable operation in cold cranking conditions. |
| 10 | 4A | Channel 4 input - immune to slow-rising inputs (Δt/ΔV down to 81 ns/V at 15 V), preventing metastability in noisy environments. |
| 11 | 5Y | Channel 5 output - maintains < 0.4 V VOL at 5.2 mA sink, ensuring valid LOW recognition by downstream Schmitt-trigger inputs. |
| 12 | 5A | Channel 5 input - supports DC-coupled connections to open-collector or push-pull sensor outputs without level-shifting resistors. |
| 13, 16 | n.c. | No connect - internally unconnected; must remain floating or tied to GND per layout best practices to avoid parasitic coupling. |
| 14 | 6A | Channel 6 input - identical electrical characteristics to pins 3/5/7/9/12; allows full utilization of all six channels in multi-sensor aggregation. |
| 15 | 6Y | Channel 6 output - fully specified for dynamic loading (CPD = 14 pF), enabling accurate power estimation in ECU thermal modeling. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for continuous operation from -40 °C to +125 °C ambient, meeting automotive powertrain and safety system reliability requirements. |
| 15 V overvoltage-tolerant inputs | Eliminates need for external series resistors or Zener clamps when interfacing with 12 V battery-sensed signals in body control modules. |
| CMOS low-power operation | ICC ≤ 2.0 μA typical at VCC = 6.0 V, enabling always-on wake-up circuitry in gateway ECUs with sub-μA standby current budgets. |
| Latch-up immunity > 100 mA | Complies with JESD78 Class II Level B, preventing destructive latch-up during load dump or jump-start events in 12 V systems. |
| High noise immunity | VIH/VIL margins exceed 1.0 V at VCC = 4.5 V, rejecting common-mode noise on long harness runs in chassis-mounted modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex non-inverting level shifting applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G34QDRYRQ1 | Single-channel, 1.65–5.5 V supply, no overvoltage tolerance beyond VCC + 0.5 V. | Requires six devices and external 15 V clamping for same function; unsuitable for direct 12 V interface. | Select only when board space permits discrete channel replication and input voltage never exceeds VCC + 0.5 V. |

FAQ
Can 74HC4050D-Q100 translate signals from 15 V to 1.8 V logic levels?
Yes - its inputs tolerate up to 15 V regardless of VCC, and with VCC = 1.8 V (within 2.0–6.0 V spec), it outputs valid 1.8 V logic levels. However, VCC minimum is 2.0 V per datasheet; operation below 2.0 V is not characterized or guaranteed. For 1.8 V systems, use VCC = 2.0 V and verify VOH/VOL against downstream receiver thresholds.
Are pins 13 and 16 (n.c.) required to be grounded or left floating?
Pins 13 and 16 are internally unconnected and must remain floating per Nexperia design. Grounding them may introduce parasitic capacitance or coupling paths that degrade noise immunity. PCB layout should avoid copper pours or traces near these pins to prevent unintended coupling in high-frequency automotive environments.
Does 74HC4050D-Q100 support hot-swap or live-insertion in 12 V systems?
It supports live insertion under defined conditions: input voltage must not exceed 15 V, VCC must be present before applying input signals, and slew rate must stay within 81 ns/V (per Table 5). The 100 mA latch-up immunity and HBM > 2000 V ESD rating provide robustness, but system-level protection (e.g., series current limiting) is still recommended for uncontrolled hot-swap scenarios.
How does propagation delay vary with supply voltage and load?
Propagation delay decreases as VCC increases: 85 ns typical at VCC = 2.0 V, 17 ns at VCC = 4.5 V, and 7 ns at VCC = 6.0 V (CL = 50 pF). Load capacitance directly impacts delay - doubling CL from 50 pF to 100 pF adds ~15% to tpd. These values are fully characterized from -40 °C to +125 °C and included in Table 7 of the datasheet.
