Product details

Overview

74HC4050PW,118 from Nexperia is a hex non-inverting level shifter IC with overvoltage-tolerant inputs (up to 15 V), designed for HIGH-to-LOW voltage translation between disparate logic domains. It operates from 2.0 V to 6.0 V supply, delivers 6 independent buffered outputs, and supports industrial temperature range (-40 °C to +125 °C) in TSSOP16 package. It enables interfacing 15 V analog or legacy logic signals to 3.3 V/5 V microcontrollers.

For engineers reviewing the 74HC4050PW,118 datasheet, 74HC4050PW,118 pinout, 74HC4050PW,118 application, or 74HC4050PW,118 equivalent, key selection criteria include input overvoltage tolerance, propagation delay at 4.5 V (9–21 ns), output drive capability (±4 mA), CMOS power efficiency, and TSSOP16 thermal derating (8.5 mW/K above 91 °C).

Technical Context

The 74HC4050PW,118 implements six independent non-inverting buffer stages, each with diode-clamped inputs rated to 15 V - enabling direct connection to higher-voltage signal sources without external resistors or translators. Its CMOS architecture ensures low static current (≤40 μA at 6 V) and high noise immunity (typical VIH = 4.2 V, VIL = 1.8 V at VCC = 6 V).

Each channel features symmetrical propagation delays (tpd = tPLH = tPHL) and transition times (tt = tTHL = tTLH), with dynamic performance specified under CL = 50 pF load. Input clamping current is limited to ±20 mA, and output short-circuit current is rated to ±25 mA per pin, supporting robust transient handling in mixed-voltage systems.

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
SN74LVC4050APWR	Lower overvoltage tolerance (5.5 V max input), 1.65–5.5 V supply range, faster tpd (5.5 ns typ at 3.3 V).	Not suitable for 12 V/15 V signal domains; limited to 3.3 V ↔ 5 V translation only.	Select when interfacing strictly LVCMOS domains and speed > power is prioritized.
74LVC1G17GW,125	Single-channel Schmitt-trigger buffer, 1.65–5.5 V supply, no overvoltage tolerance beyond VCC+0.3 V.	Requires six separate packages and routing; lacks 15 V input capability entirely.	Choose only for space-constrained single-signal cases where hysteresis is needed and voltage domains match.

Compared with SN74LVC4050APWR and 74LVC1G17GW,125, the 74HC4050PW,118 uniquely supports 15 V inputs while maintaining hex integration and industrial temperature range - making it the sole choice for cost-sensitive, high-voltage mixed-domain interfaces requiring minimal footprint and no external components.

FAQ

Can the 74HC4050PW,118 translate signals from 15 V down to 1.8 V logic?

No. While its inputs tolerate up to 15 V, the output swing is rail-to-rail between GND and VCC. To drive 1.8 V logic, VCC must be set to 1.8 V - but the device's recommended minimum supply is 2.0 V. Operation below 2.0 V is not characterized or guaranteed, and VOH/VOL specifications do not apply.

Are pins 13 and 16 (n.c.) safe to tie to ground?

Yes. Pins 13 and 16 are confirmed as no-connect terminals with no internal bonding. They may be left floating or tied to GND for mechanical stability or EMI reduction; connecting them to VCC is prohibited and may cause undefined behavior or increased leakage.

Does the 74HC4050PW,118 support bidirectional level shifting?

No. It is a unidirectional, non-inverting buffer: inputs (A pins) accept 0–15 V signals, outputs (Y pins) swing between GND and VCC only. There is no internal feedback or direction control; reverse signal flow (Y → A) is not supported and violates absolute maximum ratings.

What is the maximum capacitive load the 74HC4050PW,118 can drive reliably?

The device is characterized with CL = 50 pF for timing specs (tpd, tt). Static drive capability remains valid up to ±4 mA, implying a practical load limit of ~1000 pF at 1 MHz (based on CPD = 14 pF and dynamic power constraints). For >200 pF loads, verify signal integrity via oscilloscope measurement due to potential rise/fall time degradation.
