Product details

Overview

74HC4050PW,112 from Nexperia is a hex non-inverting HIGH-to-LOW level shifter with overvoltage-tolerant inputs (up to 15 V), designed for interfacing 5 V/3.3 V logic with higher-voltage systems. It operates from 2.0 V to 6.0 V supply, delivers ±25 mA output drive, and supports -40 °C to +125 °C ambient range in TSSOP16 package. Used in industrial I/O expansion where legacy 12 V sensors interface with modern low-voltage microcontrollers.

For engineers reviewing the 74HC4050PW,112 datasheet, 74HC4050PW,112 pinout, 74HC4050PW,112 application, or 74HC4050PW,112 equivalent, key selection criteria include input overvoltage tolerance (15 V), VIH/VIL thresholds across VCC range, propagation delay at 6.0 V (7–14 ns), and TSSOP16 thermal derating (8.5 mW/K above 91 °C).

Technical Context

The 74HC4050PW,112 implements six independent CMOS buffer stages with input clamping diodes enabling safe operation when inputs exceed VCC-critical for bidirectional voltage translation without external components. Each channel features symmetrical input protection (VIK = -0.5 V to +16 V) and rail-to-rail output swing (VOH ≥ 5.48 V @ VCC = 6.0 V, IO = -5.2 mA).

Its static behavior is defined across three temperature ranges (-40 °C to +125 °C), with guaranteed VIH ≥ 4.2 V and VIL ≤ 2.3 V at VCC = 6.0 V, and dynamic performance specified at CL = 50 pF, including tpd ≤ 14 ns and tt ≤ 13 ns under nominal 6.0 V conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	2.0 V to 6.0 V - Enables direct use with 3.3 V and 5 V logic rails without level-shifting circuitry.
Input Overvoltage Tolerance	Up to 15 V - Allows connection to 12 V sensor outputs or industrial control lines without external clamping.
Output Drive Capability	±25 mA - Sufficient to drive multiple CMOS loads or moderate capacitive bus lines (e.g., 50 pF).
Propagation Delay	7–14 ns @ VCC = 6.0 V, CL = 50 pF - Supports >35 MHz signal throughput in timing-critical digital interfaces.
Operating Temperature	-40 °C to +125 °C - Qualified for extended industrial environments including motor drives and PLC I/O modules.
Input Leakage Current	±0.5 μA max @ VI = 15 V - Minimizes loading on high-impedance source signals such as analog comparators or open-collector sensors.
Power Dissipation	500 mW (derates 8.5 mW/K above 91 °C in TSSOP16) - Requires thermal awareness in dense PCB layouts but avoids active cooling.

Pinout & Package

TSSOP16 plastic thin shrink small outline package (SOT403-1); 16-pin, 4.4 mm body width, 0.65 mm lead pitch; moisture sensitivity level MSL3 per JEDEC J-STD-020.

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	Buffer output for channel 1 - Drives downstream logic; output swing matches VCC (0 V to VCC).
3	1A	Input for channel 1 - Accepts up to 15 V regardless of VCC; clamped internally to safe levels.
4	2Y	Buffer output for channel 2 - Electrically isolated from other channels; no crosstalk in typical operation.
5	2A	Input for channel 2 - Independent overvoltage tolerance enables mixed-voltage routing on same PCB.
6	3Y	Buffer output for channel 3 - Matches timing specs of other outputs (tpd ≤ 14 ns @ 6 V).
7	3A	Input for channel 3 - Compatible with TTL, CMOS, and open-drain sources up to 15 V.
8	GND	Ground reference - Shared return path for all six buffers; must connect to low-impedance system ground plane.
9	4Y	Buffer output for channel 4 - Designed for identical electrical characteristics as 1Y–3Y.
10	4A	Input for channel 4 - No internal pull-up/down; requires external bias if used with floating sources.
11	5Y	Buffer output for channel 5 - Validated for continuous operation at 125 °C ambient.
12	5A	Input for channel 5 - Input capacitance 3.5 pF - minimizes signal distortion on fast edges.
13	n.c.	No connection - Internally unconnected; must remain unpopulated or left floating (not tied to VCC/GND).
14	6A	Input for channel 6 - Same VIH/VIL thresholds as other inputs; VIH = 4.2 V min @ VCC = 6.0 V.
15	6Y	Buffer output for channel 6 - Output low voltage ≤ 0.26 V @ IO = 5.2 mA ensures solid LOW recognition.
16	n.c.	No connection - Internally unconnected; PCB pad may be omitted or used for mechanical anchoring only.

Key Features

Feature	Design Value
Overvoltage-tolerant inputs	Rated to 15 V independent of VCC - eliminates need for external Zener clamps or resistive dividers in mixed-voltage systems.
Wide supply range	2.0 V to 6.0 V operation - supports direct integration into both 3.3 V microcontroller peripherals and 5 V legacy backplanes.
High noise immunity	Typical HNM = 1.35 V @ VCC = 4.5 V - rejects common-mode noise on industrial sensor lines without additional filtering.
Latch-up immunity	Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during transient overvoltage events.
ESD robustness	HBM > 2000 V, CDM > 1000 V - withstands handling and board-level ESD without protection diodes.

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
SN74LVC4050PWR	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 source signals stay within 0–5.5 V and board space favors TI's smaller thermal pad variant.
74LVC1G17GW,125	Single-channel Schmitt-trigger buffer; 1.65–5.5 V supply; no overvoltage tolerance	Requires six separate devices and additional PCB area; lacks input clamping for industrial transients	Use only for low-density, low-speed applications where individual channel control and hysteresis are required.

Compared with SN74LVC4050PWR and 74LVC1G17GW,125, the 74HC4050PW,112 uniquely provides 15 V input tolerance in a single 16-pin TSSOP package, eliminating external protection components and reducing bill-of-materials cost by up to 40% in mixed-voltage industrial designs.

FAQ

Can the 74HC4050PW,112 translate signals from 15 V down to 3.3 V without external components?

Yes. Its inputs tolerate up to 15 V regardless of VCC, and outputs swing rail-to-rail (0 V to VCC). With VCC = 3.3 V, it safely converts 15 V inputs to 3.3 V-compatible outputs using only internal clamping diodes-no resistors or Zeners needed. VIH remains valid at 2.3 V minimum, ensuring reliable HIGH detection.

What is the maximum capacitive load the 74HC4050PW,112 can drive while maintaining specified timing?

The device is characterized at CL = 50 pF, with tpd ≤ 14 ns and tt ≤ 13 ns at VCC = 6.0 V. Driving >100 pF increases propagation delay nonlinearly and may cause ringing; for loads >75 pF, add a series 10–33 Ω resistor near the output to dampen reflections without affecting DC levels.

Are the n.c. pins (13 and 16) required to be left floating, or can they be grounded for mechanical stability?

Pins 13 and 16 are internally unconnected and must remain electrically floating-neither tied to VCC nor GND. They may be soldered to copper pour for mechanical reinforcement only, provided no conductive path to any net is created. Grounding them risks undefined internal node biasing and potential parametric shift.

How does thermal derating apply to the 74HC4050PW,112 in TSSOP16 package at 100 °C ambient?

In TSSOP16 (SOT403-1), total power dissipation derates linearly at 8.5 mW/K above 91 °C. At 100 °C ambient, Ptot = 500 mW − (8.5 mW/K × 9 K) = 423.5 mW. This assumes still-air convection; forced airflow or thermal vias can improve effective derating margin by up to 25%.
