Product details
Overview
NC7NZ34K8X-L22236 from onsemi is a triple non-inverting buffer IC in the TinyLogic UHS family, fabricated in advanced CMOS for ultra-high-speed logic translation and signal conditioning. It operates across 1.65 V to 5.5 V VCC, delivers ±24 mA output drive at 3 V, and achieves 2.4 ns typical propagation delay into 50 pF at 5 V - used in level-shifting interfaces between mixed-voltage subsystems in portable and industrial control logic.
For engineers reviewing the NC7NZ34K8X-L22236 datasheet, pinout, applications, or equivalent options, key selection criteria include its overvoltage-tolerant inputs (up to 5.5 V independent of VCC), power-down high-impedance I/O state, and US8 package compatibility with space-constrained PCB layouts requiring 3.1 mm width and JEDEC MO-187 footprint.
Technical Context
The NC7NZ34K8X-L22236 implements three independent CMOS buffer stages with rail-to-rail input tolerance and push-pull outputs. Its architecture supports voltage-level translation (e.g., 5 V input to 3.3 V system) without external biasing, enabled by input structures that remain functional even when VCC = 0 V.
Propagation delay is tightly specified across VCC (1.8 V–5.5 V) and load conditions (15 pF and 50 pF), with guaranteed tPLH/tPHL ≤ 4.6 ns at 1.8 V/15 pF and ≤ 3.8 ns at 5 V/50 pF. Proprietary noise/EMI reduction circuitry minimizes switching-induced supply transients during high-frequency operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables single-supply operation across 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains |
| tPD (Typ) | 2.4 ns into 50 pF at 5 V - supports >200 MHz signal routing in timing-critical digital paths |
| IOH/IOL | ±24 mA at 3 V - drives multiple standard CMOS loads or short traces without buffering |
| Input Voltage Tolerance | −0.5 V to 6.5 V - allows safe 5 V inputs into 1.8 V or 2.5 V systems without clamping diodes |
| Power-Down State | High-impedance I/O when VCC = 0 V - prevents back-driving and bus contention during power sequencing |
| CIN | 2.5 pF - minimizes capacitive loading on driving gates, preserving signal edge integrity |
Pinout & Package
NC7NZ34K8X-L22236 uses the 8-lead US8 package (JEDEC MO-187, Variation CA), 3.1 mm wide, with exposed pad not connected internally. Pin 1 is located at the lower-left corner when top marking "NZ34" is read left-to-right.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A (Input) | First buffer input - accepts overvoltage-tolerant logic signals for channel 1 |
| 2 | 1Y (Output) | Non-inverting output of buffer 1 - drives downstream logic or transmission line |
| 3 | 2A (Input) | Second buffer input - electrically isolated from other channels, same voltage tolerance |
| 4 | GND | Ground reference for all buffers and internal circuitry - must be low-impedance connection |
| 5 | 3Y (Output) | Non-inverting output of buffer 3 - shares VCC and GND with other channels |
| 6 | 2Y (Output) | Non-inverting output of buffer 2 - supports simultaneous fan-out to multiple loads |
| 7 | 3A (Input) | Third buffer input - fully independent; no crosstalk or shared path with A1/A2 |
| 8 | VCC | Supply voltage input - powers all three buffers; decoupling capacitor required near pin |
Key Features
| Feature | Design Value |
|---|---|
| Ultra High Speed | 2.4 ns typical tPD at 5 V enables clean signal pass-through in sub-5 ns timing windows |
| Overvoltage-Tolerant Inputs | Inputs accept up to 5.5 V regardless of VCC, eliminating need for external level shifters in mixed-voltage designs |
| Power-Down High-Z I/O | Entire device enters tri-state mode when VCC = 0 V - critical for hot-swap and power-gated subsystems |
| Low Input Capacitance | 2.5 pF CIN reduces loading on preceding drivers, preserving rise/fall times in cascaded logic |
| Pb-Free & RoHS Compliant | US8 package meets JEDEC J-STD-020B reflow profile and environmental compliance requirements |
Applications
| Industrial PLC I/O Expansion | Portable Device Power Sequencing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC3G34DCUR | 3.3 V only VCC range (1.65–5.5 V same, but rated performance optimized for 3.3 V); 3.5 ns tPD typ at 3.3 V/50 pF | Lacks overvoltage-tolerant inputs - requires external clamping for 5 V inputs | Prefer when system operates exclusively at 3.3 V and cost is primary constraint |
| 74LVC1G34GW,125 | Single-buffer device; identical US8 footprint but only one channel; 3.2 ns tPD typ at 3.3 V/50 pF | Requires three devices to match NC7NZ34K8X-L22236's triple functionality - increases layout area and routing complexity | Select only if channel count is flexible and board space permits discrete channel placement |
Compared with SN74LVC3G34DCUR and 74LVC1G34GW,125, the NC7NZ34K8X-L22236 uniquely combines triple-channel density, 5.5 V input tolerance, and sub-2.5 ns delay in a single US8 package - making it optimal for compact, mixed-voltage logic interfacing where channel integration and voltage robustness are mandatory.

FAQ
What is the maximum operating temperature range for the NC7NZ34K8X-L22236?
The NC7NZ34K8X-L22236 is rated for continuous operation from −40 °C to +85 °C ambient temperature. This range is validated per the Recommended Operating Conditions table in the official datasheet, and thermal resistance (θJA) is specified as 250 °C/W for the US8 package - enabling reliable use in industrial enclosures and automotive under-hood environments with proper board-level thermal design.
Does the NC7NZ34K8X-L22236 support 1.8 V logic levels?
Yes, the NC7NZ34K8X-L22236 fully supports 1.8 V operation: VCC can be set from 1.65 V to 5.5 V, and DC electrical characteristics including VIH (0.65 × VCC) and VOL (<0.24 V at 4 mA) are guaranteed at 1.8 V ±0.15 V. AC propagation delay remains ≤4.6 ns into 15 pF at this voltage, confirming robust 1.8 V system compatibility.
Is the NC7NZ34K8X-L22236 pin-compatible with other TinyLogic triple buffers?
No - the NC7NZ34K8X-L22236 uses a fixed US8 pinout (1A, 1Y, 2A, GND, 3Y, 2Y, 3A, VCC) that differs from alternate packages like MicroPak (e.g., NC7NZ34L8X). While functionally identical to NC7NZ34K8X, the -L22236 suffix denotes a specific tape-and-reel shipment variant, not a pinout revision. Always verify pin mapping against Figure 4 in the datasheet before layout.
Can the NC7NZ34K8X-L22236 drive a 50 Ω transmission line directly?
No - the NC7NZ34K8X-L22236 is not designed for 50 Ω line driving. Its output structure targets CMOS load capacitance (e.g., 50 pF), not resistive termination. Driving 50 Ω would exceed ±24 mA absolute maximum ratings at typical logic voltages and cause excessive VOL/VOH deviation. Use dedicated line drivers (e.g., SN65LVDS1) for impedance-matched signaling.
What is the quiescent supply current of the NC7NZ34K8X-L22236 at 3.3 V?
The NC7NZ34K8X-L22236 draws ≤1.0 µA typical quiescent supply current (ICC) at 3.3 V and 25 °C, with a maximum of 10 µA over the full −40 °C to +85 °C temperature range. This ultra-low static power enables use in always-on monitoring circuits and battery-backed subsystems without measurable impact on standby current budgets.
