Product details
Overview
NC7SV34P5X from onsemi is a single-channel ultra-low-power (ULP-A) CMOS buffer IC in SC-88A (SOT-353) package, operating from 0.9 V to 3.6 V supply. It delivers 1.4 ns typical propagation delay at 3.3 V, supports 24 mA output drive, and features over-voltage tolerant inputs/outputs up to 3.6 V - used in level-shifting and signal conditioning for portable battery-powered logic interfaces.
For engineers reviewing the NC7SV34P5X datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage range compatibility (0.9–3.6 V), IOFF-enabled partial power-down capability, input/output overvoltage tolerance, low dynamic power consumption (CPD = 10.0 pF), and SC-88A footprint constraints in space-constrained designs.
Technical Context
The NC7SV34P5X implements a non-inverting buffer with rail-to-rail input and output swing across its full 0.9–3.6 V VCC range. Its IOFF circuitry disables I/O leakage paths when VCC = 0 V, enabling safe back-driving in partial power-down systems.
Propagation delay varies with load and supply: 3.3 ns max at 3.3 V / 500 Ω / 30 pF, and 16.9 ns max at 1.3 V / 2 kΩ / 15 pF. Input thresholds scale with VCC (VIH = 0.65×VCC, VIL = 0.35×VCC) for robust noise margin across voltage domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.9 V to 3.6 V - enables direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic families without level shifters |
| tPD (Typ) | 1.4 ns at 3.3 V - supports >300 MHz signal integrity in short-path routing |
| IOFF Leakage | ≤0.5 µA at VCC = 0 V - prevents current backflow during system sleep modes |
| Output Drive | ±24 mA at 3.3 V - drives multiple standard CMOS loads or small capacitive traces |
| Input Tolerance | Up to 3.6 V independent of VCC - allows hot-swap and mixed-voltage board interfacing |
| CPD | 10.0 pF - determines no-load dynamic power as PD = 10.0 × VCC² × fIN |
| Operating Temp | −40 °C to +85 °C - qualified for industrial ambient environments |
Pinout & Package
NC7SV34P5X is packaged in SC-88A (SOT-353), a 5-pin, 1.25 mm × 2.1 mm surface-mount package with 0.65 mm pitch. Pin 1 is marked by a dot or beveled edge per JEDEC MO-203AA.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Internally unconnected - must be left floating or tied to GND per layout best practice |
| 2 | Input (A) | Non-inverting logic input - accepts 0.9–3.6 V signals regardless of VCC |
| 3 | GND | Ground reference for all internal circuitry and output return path |
| 4 | Output (Y) | Buffered non-inverted output - drives loads up to ±24 mA at 3.3 V |
| 5 | VCC | Positive supply - powers internal logic and defines output high-level threshold |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low-power operation | ICC ≤ 0.9 µA at VCC = 3.6 V - extends battery life in always-on sensor nodes |
| IOFF partial power-down | Blocks I/O leakage when VCC = 0 V - eliminates cross-talk in multi-rail powered subsystems |
| Over-voltage tolerant I/O | Withstands 3.6 V input/output even at VCC = 0.9 V - simplifies mixed-voltage interconnect |
| SC-88A and MicroPak options | SC-88A (NC7SV34P5X) offers proven thermal performance (θJA = 377 °C/W) and reworkability |
| Pb-Free/RoHS compliance | Halogen-free/BFR-free construction - meets IPC-1752A Class 2 material declarations |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NC7SZ34P5X | Higher ICC (1.5 µA typ), same SC-88A package, identical pinout - no IOFF support | Lacks partial power-down protection; unsuitable for systems requiring VCC = 0 V isolation | Select NC7SZ34P5X only if IOFF is not required and lower quiescent current is not critical |
| SN74LVC1G34DBVR | Wider VCC range (1.65–5.5 V), higher drive (32 mA), but no IOFF and larger SOT-23-5 footprint | Requires PCB redesign due to different pinout and thermal pad; incompatible with 0.9 V operation | Choose SN74LVC1G34DBVR only when 5 V compatibility or higher drive is mandatory and layout change is acceptable |
Compared with NC7SV34P5X, NC7SZ34P5X trades IOFF for slightly higher static current, while SN74LVC1G34DBVR sacrifices ultra-low-voltage operation and partial power-down for broader voltage range and higher output current - making NC7SV34P5X uniquely suited for sub-1.2 V battery-powered systems requiring safe power sequencing.

FAQ
What is the minimum supply voltage for reliable operation of the NC7SV34P5X?
The NC7SV34P5X is fully specified down to 0.9 V VCC, with guaranteed functionality across −40 °C to +85 °C. At 0.9 V, VIH is 0.5 V and VIL is 0.5 V (thresholds are fixed, not ratio-based, below 1.1 V). The NC7SV34P5X maintains valid logic levels and propagation delay within datasheet limits at this voltage, making it suitable for single-cell Li-ion or coin-cell powered circuits.
Does the NC7SV34P5X support true tri-state operation?
No, the NC7SV34P5X is a non-inverting buffer with no enable or output control pin - it does not provide tri-state functionality. Its IOFF feature only blocks leakage when VCC = 0 V; the output remains actively driven high or low based on input state whenever VCC is powered. For tri-state buffering, consider onsemi's NC7SV125 or NC7SV126 series instead of NC7SV34P5X.
Can the NC7SV34P5X be used to interface a 3.3 V FPGA I/O with a 1.2 V microcontroller?
Yes - the NC7SV34P5X accepts 3.3 V inputs while operating at VCC = 1.2 V, thanks to its over-voltage tolerant inputs rated up to 3.6 V. Its output swings rail-to-rail (0 V to 1.2 V), matching the microcontroller's input thresholds. This eliminates external level-shifting components, provided the FPGA output can drive the NC7SV34P5X's 2 pF input capacitance and DC leakage.
What is the thermal resistance (θJA) of the NC7SV34P5X in its SC-88A package?
The NC7SV34P5X in SC-88A package has a junction-to-ambient thermal resistance (θJA) of 377 °C/W, measured per JESD51-7 on an FR4 board with minimum pad spacing and no airflow. This value assumes a 10 mm × 1 inch, 2-ounce copper trace. Under typical 1–2 mA ICC conditions, self-heating remains negligible (<1 °C rise), confirming suitability for thermally constrained PCB layouts.
Is the NC7SV34P5X pin-compatible with other TinyLogic buffers like NC7SZ34 or NC7WZ34?
No - the NC7SV34P5X uses a 5-pin SC-88A package with pinout: Pin 1 = NC, Pin 2 = A, Pin 3 = GND, Pin 4 = Y, Pin 5 = VCC. In contrast, NC7SZ34P5X shares this pinout, but NC7WZ34 is a dual buffer in SC-70-6 (6-pin) with different pin assignment. Only NC7SZ34P5X is pin-compatible with NC7SV34P5X; all others require PCB redesign.
