Product details
Overview
MC74LVX50D from onsemi is a hex non-inverting buffer IC designed for level-shifting and noise-immune signal distribution in mixed-voltage systems. It features six independent buffer channels, 2.0 V to 3.6 V supply operation, 4.1 ns typical propagation delay at 3.3 V, and 5.5 V-tolerant inputs-enabling reliable interfacing between 3.3 V logic and legacy 5.0 V subsystems in industrial control backplanes.
For engineers reviewing the MC74LVX50D datasheet, pinout, applications, or equivalent options, key selection criteria include input voltage tolerance (up to 6.5 V), output drive capability (±25 mA), low-noise performance (VOLP ≤ 0.5 V), and TSSOP-14 package compatibility with high-density PCB layouts.
Technical Context
The MC74LVX50D implements three-stage CMOS buffering with fully buffered outputs to ensure stable switching and high noise immunity (VNIH/VNIL = 28% VCC). Its input structure supports overvoltage tolerance up to 6.5 V independent of VCC, enabling safe connection to 5 V buses while operating from a 3.3 V rail.
All six channels are electrically isolated with balanced tPLH/tPHL propagation delays and guaranteed output-to-output skew ≤1.5 ns under 50 pF load. The device includes power-down protection on inputs and meets JEDEC JESD78 latch-up immunity (±300 mA) at 85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 3.6 V - Enables direct integration into 3.3 V embedded systems without level translators. |
| Input Voltage Tolerance | Up to 6.5 V - Allows safe interface with 5.0 V logic families without external clamping. |
| Propagation Delay | 4.1 ns (typ) at VCC = 3.3 V, CL = 15 pF - Supports >100 MHz signal distribution in timing-critical paths. |
| Output Drive Strength | ±25 mA - Sufficient to drive multiple CMOS loads or moderate capacitive traces (≤50 pF). |
| Quiescent Supply Current | 2.0 µA (max) at TA = 25°C - Enables use in battery-backed or low-power standby circuits. |
| Noise Immunity | VNIH = VNIL = 28% VCC - Provides robust operation in electrically noisy industrial environments. |
| Dynamic Output Noise | VOLP ≤ 0.5 V (max) - Limits ground bounce and crosstalk in dense routing scenarios. |

|---|---|---|
| 1, 3, 5, 9, 11, 13 | Input A1–A6 | CMOS-compatible inputs with 6.5 V tolerance; require defined logic level (no floating). |
| 2, 4, 6, 8, 10, 12 | Output Y1–Y6 | Non-inverting buffered outputs capable of ±25 mA sink/source per channel. |
| 7 | GND | Digital ground reference for all I/O and internal circuitry; must be low-impedance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC125APWR | 4-channel tri-state buffer; 1.65–3.6 V supply; no 5 V input tolerance. | Requires external pull-ups for 5 V interface; unsuitable for direct 5 V input connection. | Select only if tri-state control is needed and all inputs remain ≤3.6 V. |
| 74LVC244APW | Octal non-inverting buffer; same voltage range; 5 V-tolerant inputs confirmed. | Provides two extra channels but larger TSSOP-20 footprint; higher quiescent current (10 µA max). | Choose when additional drive channels justify increased board area and power budget. |
Compared with SN74LVC125APWR and 74LVC244APW, the MC74LVX50D uniquely combines six-channel non-inverting buffering, 6.5 V input tolerance, and ultra-low 2.0 µA ICC in a compact TSSOP-14 package-making it optimal for space-constrained, mixed-voltage industrial interfaces where simplicity and reliability are prioritized over tri-state flexibility or channel count expansion.

FAQ
What is the maximum input voltage rating for MC74LVX50D?
The MC74LVX50D supports DC input voltages up to 6.5 V, independent of VCC. This allows direct connection to 5.0 V logic buses while operating from a 2.0–3.6 V supply. Exceeding 6.5 V may damage the input structure. The MC74LVX50D datasheet specifies VI(max) = 6.5 V in the Maximum Ratings table, verified per JEDEC standards.
Does MC74LVX50D support true 5 V-tolerant inputs?
Yes, the MC74LVX50D provides guaranteed 5.5 V-tolerant inputs across its full operating temperature range (−40°C to +85°C), with absolute maximum input rating of 6.5 V. This is implemented via internal clamp structures and confirmed in both the Recommended Operating Conditions and Maximum Ratings sections of the official onsemi datasheet for MC74LVX50D.
What is the propagation delay variation between channels of MC74LVX50D?
The MC74LVX50D guarantees output-to-output skew ≤1.5 ns (tOSHL/tOSLH) under identical load conditions (CL = 50 pF, VCC = 3.3 V), ensuring tightly aligned timing across all six buffer channels. This specification is explicitly tested and documented in the AC Electrical Characteristics table of the MC74LVX50D datasheet.
Can MC74LVX50D be used with a 2.5 V supply?
Yes, the MC74LVX50D operates across 2.0 V to 3.6 V, including 2.5 V. At VCC = 2.5 V, propagation delay increases to 6.2 ns (typ) with CL = 15 pF, and output drive strength remains sufficient for standard CMOS loads. All DC parameters-including VIH/VIL thresholds and VOL/VOH levels-are characterized down to 2.0 V in the MC74LVX50D datasheet.
Is MC74LVX50D pin-compatible with other hex buffer ICs in TSSOP-14?
No documented pin-compatible alternatives exist for the MC74LVX50D in TSSOP-14. While functional equivalents like 74LVC244APW offer 5 V-tolerant inputs, they use different pinouts (e.g., separate VCC/GND pairs per group) and require layout revision. The MC74LVX50D uses a single VCC (pin 14) and GND (pin 7), with alternating A/Y pins-confirmed in Figure 2 (Logic Symbol) and PIN ASSIGNMENT diagram of the MC74LVX50D datasheet.
