Product details
Overview
74HC4050DB,112 from Nexperia is a hex non-inverting HIGH-to-LOW level shifter IC with overvoltage-tolerant inputs (up to 15 V), operating across 2.0–6.0 V supply, delivering 6 independent buffered outputs, and rated for -40 °C to +125 °C ambient temperature - used in interfacing legacy 5 V/12 V logic to modern 3.3 V or 2.5 V microcontrollers.
For engineers reviewing the 74HC4050DB,112 datasheet, 74HC4050DB,112 pinout, 74HC4050DB,112 application, or 74HC4050DB,112 equivalent, key selection criteria include input overvoltage tolerance, propagation delay at 4.5 V (9–17 ns), output drive capability (±5.2 mA), SO16 package compatibility, and level-shifting functionality without external biasing.
Technical Context
The 74HC4050DB,112 implements six independent CMOS buffer stages, each accepting high-voltage inputs (up to 15 V) while powered from a lower VCC (2.0–6.0 V), enabling unidirectional HIGH-to-LOW voltage translation without pull-up resistors or external components. Its input protection includes polysilicon clamping resistors and diodes to VCC and GND.
Each buffer exhibits rail-to-rail output swing (VOH ≥ 4.4 V at VCC = 4.5 V, IO = −4.0 mA; VOL ≤ 0.26 V at same conditions), supports dynamic operation up to 26 ns propagation delay (−40 °C to +85 °C, VCC = 4.5 V), and maintains static input leakage < ±0.5 μA at VI = 15 V - critical for low-power mixed-voltage system interconnects.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - enables direct interface with 2.5 V, 3.3 V, and 5 V logic domains without level-shifting circuitry. |
| Input Overvoltage Tolerance | Up to 15 V - allows safe connection to 12 V industrial sensors or legacy TTL outputs while powered from 3.3 V. |
| Propagation Delay (VCC = 4.5 V) | 9–17 ns (25 °C), ≤26 ns (−40 °C to +85 °C) - ensures timing integrity in medium-speed digital control and data acquisition paths. |
| Output Drive Strength | ±5.2 mA at VCC = 6.0 V - sufficient to drive multiple 74HC inputs or moderate capacitive loads (<50 pF) without signal degradation. |
| Operating Temperature Range | −40 °C to +125 °C - qualified for under-hood automotive modules, industrial PLC I/O, and extended-temperature embedded controllers. |
| Input Leakage Current (VI = 15 V) | < ±0.5 μA - minimizes loading on high-impedance source signals such as open-collector sensor outputs. |
| Power Dissipation Capacitance | 14 pF - enables accurate dynamic power estimation (PD = CPD × VCC² × fi × N) for thermal design in dense PCB layouts. |
Pinout & Package
74HC4050DB,112 is housed in a 16-pin SO16 (SOT109-1) plastic small outline package, 3.9 mm body width, with 1.27 mm lead pitch and gull-wing leads. Pin 1 is marked by a bevelled corner or index notch.
| 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 | Buffered output of channel 1 - provides inverted-phase, level-shifted replica of 1A input signal. |
| 3 | 1A | Input for channel 1 - accepts 0–15 V logic; internally clamped to VCC/GND; no external pull-up required. |
| 4 | 2Y | Buffered output of channel 2 - electrically isolated from other channels; supports independent load routing. |
| 5 | 2A | Input for channel 2 - identical electrical behavior to 1A; enables parallel multi-signal translation. |
| 6 | 3Y | Buffered output of channel 3 - shares same VCC/GND reference but no internal crosstalk with adjacent channels. |
| 7 | 3A | Input for channel 3 - tolerant of floating or high-Z states; draws negligible current when inactive. |
| 8 | GND | Ground reference - must be connected to system 0 V plane with low-inductance path to minimize ground bounce. |
| 9 | 4Y | Buffered output of channel 4 - designed for fan-out to multiple downstream CMOS inputs (e.g., MCU GPIOs). |
| 10 | 4A | Input for channel 4 - compatible with 12 V switch closures, optocoupler collectors, or relay contacts. |
| 11 | 5Y | Buffered output of channel 5 - supports hot-swap-safe operation due to overvoltage-tolerant input structure. |
| 12 | 5A | Input for channel 5 - immune to transient overshoot up to 16 V (absolute max rating), enhancing robustness. |
| 13 | n.c. | No connect - left unconnected; not bonded internally; must remain floating or tied to GND only if required by layout. |
| 14 | 6A | Input for channel 6 - fully functional and electrically identical to other A pins; enables full hex utilization. |
| 15 | 6Y | Buffered output of channel 6 - final output in sequence; matches timing and drive specs of all Y pins. |
| 16 | n.c. | No connect - unused pad; no internal connection; avoid solder bridging or routing traces to this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Overvoltage-tolerant inputs | Withstands 15 V inputs while powered from 2.0–6.0 V - eliminates need for external resistive dividers or dedicated translators. |
| CMOS low-power operation | ICC ≤ 2.0 μA typical at VCC = 6.0 V, VI = 15 V - reduces quiescent current in always-on monitoring circuits. |
| High noise immunity | VIH/VIL thresholds tightly specified (e.g., VIH = 3.15 V min at VCC = 4.5 V) - rejects EMI-induced glitches in industrial environments. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during voltage transients or hot-plug events. |
| ESD robustness | HBM > 2000 V, CDM > 1000 V - withstands handling and board-level ESD without protection diodes or shielding. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex non-inverting level shifter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC4050APWR | Lower VCC range (1.65–5.5 V); input tolerance limited to VCC + 0.5 V (no 15 V overvoltage support) | Not suitable for 12 V sensor interfacing; requires external clamping for >5.5 V inputs | Select only when all sources are within 0–5.5 V and board space favors TSSOP-16. |
| 74LVCH16244ADGG | 16-bit, 3-state, 3.3 V–5 V dual-supply; higher pin count (48-pin TSSOP); supports bidirectional translation | Overkill for simple 6-channel unidirectional use; adds complexity in enable/control logic | Prefer only when scalable, configurable I/O expansion with direction control is required. |
Compared with SN74LVC4050APWR and 74LVCH16244ADGG, the 74HC4050DB,112 uniquely delivers 15 V input tolerance in a compact SO16 package with zero external components - making it optimal for cost-sensitive, high-reliability unidirectional level shifting where legacy voltage domains dominate.

FAQ
Can 74HC4050DB,112 translate signals from 15 V down to 1.8 V?
No. While its inputs tolerate up to 15 V, the minimum recommended VCC is 2.0 V per datasheet Section 8. Operation below 2.0 V risks undefined output levels, increased propagation delay, and potential failure to meet VOH/VOL specifications - 1.8 V systems require alternative translators like the TXB0106.
Is pin 13 (n.c.) required to be grounded?
No. Pin 13 is internally unconnected and must remain floating. Grounding it offers no benefit and may introduce unintended parasitic coupling or violate JEDEC SO16 mechanical standards. The datasheet explicitly lists it as "not connected" with no tie recommendation.
Does 74HC4050DB,112 support bidirectional level shifting?
No. It is strictly unidirectional: inputs (A pins) accept high-voltage signals, outputs (Y pins) deliver low-voltage CMOS-compatible signals. There is no internal feedback path or direction control - bidirectional use would require external circuitry or a dedicated device like the TXS0108E.
What is the maximum capacitive load this IC can drive reliably?
At VCC = 4.5 V and CL = 50 pF, propagation delay remains within spec (≤21 ns over temperature). Driving >100 pF increases transition time and may cause timing violations; for heavier loads, add series termination or use a buffer with higher drive strength like the 74LVC1G125.
