Nexperia USA Inc. 74HC4050D,653

Overview

74HC4050D,653 from Nexperia is a hex non-inverting HIGH-to-LOW level shifter IC with overvoltage-tolerant inputs (up to 15 V), 2.0–6.0 V supply range, and SO16 (SOT109-1) package. It enables interfacing between higher-voltage logic domains (e.g., 12 V sensors) and lower-voltage 3.3 V or 5 V microcontrollers while maintaining CMOS low power and high noise immunity. Used in industrial I/O conditioning and mixed-voltage sensor signal routing.

For engineers reviewing the 74HC4050D,653 datasheet, 74HC4050D,653 pinout, 74HC4050D,653 application, or 74HC4050D,653 equivalent, key selection criteria include input overvoltage tolerance (15 V), propagation delay at 6 V (7–14 ns), output drive capability (±5.2 mA), operating temperature range (−40 °C to +125 °C), and SO16 package compatibility with legacy 74HC layouts.

Technical Context

The 74HC4050D implements six independent non-inverting buffer channels, each with diode-clamped inputs rated for 15 V absolute maximum-enabling direct connection to 12 V or 5 V logic without external resistors. Its internal structure includes polysilicon input protection resistors and CMOS output stages optimized for rail-to-rail swing and low static current.

It operates across two voltage domains: input pins accept up to 15 V regardless of VCC (2.0–6.0 V), while outputs swing between GND and VCC. This decoupling allows true HIGH-to-LOW translation-e.g., converting 12 V TTL signals to 3.3 V CMOS levels-without level-shifting ICs or discrete solutions.

FAQ

Can 74HC4050D,653 translate 12 V inputs to 3.3 V outputs without external components?

Yes. Its inputs tolerate up to 15 V regardless of VCC, and outputs swing rail-to-rail between GND and VCC. With VCC = 3.3 V, it directly converts 12 V logic HIGH to 3.3 V logic HIGH while maintaining valid VOH/VOL levels per JEDEC standards-no resistors, Zeners, or MOSFETs required.

What is the maximum capacitive load the 74HC4050D,653 can drive reliably?

The device is characterized up to 50 pF load capacitance per output, with propagation delay and transition time specified at that condition. Driving >50 pF increases tpd and tt, but functional operation is maintained up to ~100 pF with minor timing degradation-verified via Nexperia's dynamic characterization data and application notes on capacitive loading.

Are pins 13 and 16 internally connected or should they be left floating?

Pins 13 and 16 are explicitly designated "n.c." (not connected) in the datasheet pin description table and functional diagrams. They are unconnected inside the die and must remain electrically floating-neither tied to VCC nor GND-to avoid unintended current paths or parasitic coupling.

Does 74HC4050D,653 support hot insertion or live signal connection?

No. While its inputs tolerate 15 V statically, the device lacks hot-swap protection circuitry such as slew-rate limiting or current limiting on inputs. Connecting active 12 V signals before VCC ramp-up may cause latch-up or exceed IOK limits; power sequencing (VCC first, then inputs) is required per JEDEC JESD78 compliance guidelines.
