Product details

Overview

M74HC4050RM13TR from STMicroelectronics is a high-speed CMOS hex non-inverting buffer/level shifter in TSSOP-16 package, operating from 2V to 6V supply, with 8ns typical propagation delay at 6V, ±5.2mA output drive, and input tolerance up to 13V - used for logic-level translation between 3.3V/5V domains in industrial control I/O interfaces.

For engineers reviewing the M74HC4050RM13TR datasheet, M74HC4050RM13TR pinout, M74HC4050RM13TR application, or M74HC4050RM13TR equivalent, key selection criteria include V_IN tolerance (up to 13V), symmetrical output drive (|I_OH| = I_OL ≥ 6mA), wide V_CC range (2–6V), noise immunity (V_NIH/V_NIL ≥ 28% V_CC), and TSSOP-16 thermal profile for space-constrained PCBs.

Technical Context

This device implements six independent non-inverting buffer stages using silicon gate C2MOS technology, each with three internal logic stages to enhance noise rejection and output stability. Input protection includes dedicated V_CC-side clamping diodes enabling safe 13V-tolerant inputs while powered from as low as 2V.

It supports bidirectional level shifting without external components: high-impedance inputs accept voltages beyond V_CC, while outputs swing rail-to-rail within V_CC bounds. Propagation delays are balanced (t_PLH ≅ t_PHL) and load-dependent - 13ns max at 6V/50pF across full temperature range (−55°C to +125°C).

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	2V to 6V - enables interoperability across 2.5V, 3.3V, and 5V logic families
t_PD (Typ)	8ns at V_CC = 6V, CL = 50pF - supports >25MHz signal buffering in timing-critical paths
I_OH/I_OL	≥6mA (min) - drives standard TTL loads and multiple CMOS inputs without fanout limitation
V_IN Max	13V - allows direct interface to higher-voltage sensors or legacy 12V control signals
V_NIH/V_NIL	≥28% V_CC - rejects >1.7V of common-mode noise on 6V-supplied systems
I_CC (Max)	1µA at T_A = 25°C - enables ultra-low static power in battery-backed monitoring circuits
C_PD	26pF - predicts dynamic current draw of ~156µA at 1MHz and 6V (ICC = CPD × VCC × fIN)

Pinout & Package

TSSOP-16 (Thin Shrink Small Outline Package), 4.9 × 6.4 mm body, 0.65 mm pitch, 1.2 mm height - optimized for automated SMT assembly and thermal dissipation in dense industrial PCB layouts.

Pin/Terminal	Circuit Role	Design Meaning
1, 3, 5, 9, 11, 14	1A–6A Inputs	High-impedance CMOS inputs with 13V-tolerant clamping diodes; no pull-up/down required
2, 4, 6, 10, 12, 15	1Y–6Y Outputs	Push-pull CMOS outputs with symmetrical sourcing/sinking capability (≥6mA)
8	GND	Signal reference and return path for all I/O; must be low-inductance connection
1	V_CC	Positive supply rail (2–6V); bypass capacitor (100nF) required near pin for AC stability
13, 16	NC	No internal connection - must remain unconnected; not usable as heatsink or test points

Key Features

Feature	Design Value
13V-tolerant inputs	Enables direct interfacing to 12V sensor outputs or industrial fieldbus nodes without external resistive dividers
Rail-to-rail output swing	Ensures full logic-high/low margins into downstream 3.3V or 5V receivers under varying load conditions
Balanced t_PLH/t_PHL	Maintains 50% duty cycle integrity in clock distribution or PWM signal conditioning applications
Low input leakage (±1µA)	Preserves accuracy in high-impedance analog multiplexer control or precision voltage divider biasing
Wide temperature range	Guarantees operation from −55°C to +125°C - qualified for under-hood automotive and factory-floor environments

Equivalent & Alternatives

The following parts are listed as comparable options for similar hex non-inverting buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74HC4050PWR	Same logic function, identical AC specs, but rated only to +85°C ambient; lower V_IN tolerance (7V max)	Not suitable for extended-temperature industrial or automotive under-hood use	Select when cost sensitivity outweighs temperature or voltage margin requirements
74LVC4050PW	Lower V_CC range (1.65–5.5V); higher speed (t_PD = 5.2ns typ); no 13V input tolerance	Cannot interface directly with 12V sensors; requires external protection circuitry	Prefer for high-speed, low-voltage-only designs where 3.3V/5V compatibility suffices

Compared with SN74HC4050PWR and 74LVC4050PW, M74HC4050RM13TR uniquely combines extended temperature support (−55°C to +125°C), 13V input tolerance, and TSSOP-16 packaging - making it the only option for ruggedized, mixed-voltage industrial I/O without redesign.

FAQ

Can M74HC4050RM13TR safely interface a 12V sensor output to a 3.3V microcontroller?

Yes. Its inputs tolerate up to 13V regardless of V_CC level, and internal clamping diodes route excess voltage to V_CC or GND. With V_CC = 3.3V, it translates 12V logic-high to 3.3V output while maintaining full noise margin and drive strength - no external components needed.

What is the maximum capacitive load this device can drive reliably?

At V_CC = 6V, the device maintains ≤20ns propagation delay with CL ≤ 50pF per channel. For heavier loads (e.g., 100pF), t_PD increases to ≤125ns (−55°C to +125°C), but output drive remains stable up to 50pF without waveform degradation or shoot-through risk.

Are pins 13 and 16 internally connected or usable for grounding?

No. Pins 13 and 16 are explicitly marked "NC" (Not Connected) in the datasheet and have no internal bond wire or silicon connection. They must remain unconnected - using them as ground ties or thermal pads violates STMicroelectronics' mechanical and reliability specifications and may cause parametric drift.

How does its noise immunity compare to standard 74HC4050 variants?

M74HC4050RM13TR guarantees V_NIH and V_NIL ≥ 28% V_CC across −55°C to +125°C, exceeding the 20% minimum typical of generic 74HC4050s. This is achieved via enhanced input stage design and tighter process control - critical for reliable operation in electrically noisy factory or vehicle environments.
