Product details

Overview

74LVC1G34GX/S500,125 from Nexperia is a single non-inverting buffer with 3.6 V max supply voltage, ±24 mA output drive, 3.7 ns typical propagation delay at 3.3 V, and operates from -40 °C to +125 °C - used in level-shifting I/O interfaces for portable microcontroller peripherals.

For engineers reviewing the 74LVC1G34GX/S500,125 datasheet, 74LVC1G34GX/S500,125 pinout, 74LVC1G34GX/S500,125 application, or 74LVC1G34GX/S500,125 equivalent, key selection factors include output drive strength, rail-to-rail input compatibility, low dynamic power consumption, and guaranteed operation across extended industrial temperature range.

Technical Context

This device implements a CMOS-based single-channel non-inverting buffer with TTL-compatible inputs and push-pull outputs. It supports mixed-voltage interfacing between 1.65 V and 3.6 V logic domains while maintaining full 3.6 V output swing.

The LVC family architecture ensures low static current (max 10 µA at 3.6 V), fast edge rates (t_r/t_f ≤ 3.0 ns), and robust ESD protection (HBM ≥ 8 kV), enabling reliable use in noise-sensitive digital signal routing paths.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	1.65 V to 3.6 V - enables direct interface with 1.8 V, 2.5 V, and 3.3 V logic families without level shifters.
Output Drive	±24 mA at V_CC = 3.3 V - sufficient to drive two 50 Ω transmission lines or one 15 pF load with <4 ns rise/fall times.
Propagation Delay	3.7 ns typical at V_CC = 3.3 V, C_L = 50 pF - meets timing budget for sub-100 MHz clock distribution and control signal buffering.
Operating Temp	−40 °C to +125 °C - qualified for under-hood automotive modules and industrial PLC I/O expansion cards.
Input Threshold	V_IL ≤ 0.63 V, V_IH ≥ 1.7 V at V_CC = 3.3 V - guarantees clean switching with 1.8 V CMOS outputs and legacy 3.3 V TTL sources.
Quiescent Current	≤10 µA at V_CC = 3.6 V - minimizes standby power in battery-backed sensor nodes and always-on wake-up circuits.

Pinout & Package

Supplied in ultra-small XSON6 (1.2 × 1.0 mm) package with 0.5 mm pitch, optimized for high-density PCB layouts in space-constrained applications such as wearables and IoT edge nodes.

Pin/Terminal	Circuit Role	Design Meaning
1	Input (A)	CMOS/TTL-compatible digital input accepting 1.65–3.6 V logic levels; no internal pull-up/down.
2	GND	Ground reference for both input threshold and output driver; must be low-impedance connection.
3	Output (Y)	Push-pull CMOS output capable of sourcing/sinking ±24 mA; rail-to-rail swing with defined VOH/VOL.
4	N/C	No internal connection; left floating or tied to GND per layout best practice for thermal stability.
5	V_CC	Positive supply rail; bypass capacitor (100 nF) required within 3 mm for stable high-speed operation.
6	N/C	No internal connection; electrically isolated; may be used as thermal pad anchor if soldered to ground plane.

Key Features

Feature	Design Value
Wide Supply Range	1.65–3.6 V operation allows seamless integration into multi-rail systems without external regulators.
High-Speed Performance	3.7 ns t_PD at 3.3 V enables use in 100 Mbps digital control links and SPI clock buffering.
Low Dynamic Power	Typical ICC of 1.2 µA at 1 MHz toggle rate reduces average power in duty-cycled I/O expanders.
ESD Robustness	8 kV HBM rating eliminates need for external TVS diodes in handheld device button debouncing circuits.

Applications

Use Scenario: Conditioning CC1/CC2 detection signals in USB Type-C receptacle designs before reaching the port controller.

IC Role / Device Role / Timing Role: Signal integrity buffer ensuring clean, fast-rising CC line transitions during plug insertion events.

Use Value: Prevents false attach/detach detection caused by trace capacitance-induced slow edges on 1.2 mm long CC traces.

Automotive Body Control Module

Industrial Sensor Interface

Use Scenario: Driving LIN bus transceiver enable lines in door module ECUs operating across −40 °C to +125 °C ambient.

Use Value: Eliminates need for dual-supply level translators while maintaining AEC-Q100 Grade 1 qualification via package and process.

Use Scenario: Isolating analog sensor ADC reference switching logic from noisy digital power domains in factory-floor pressure transmitters.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G34DBVR	Same logic function and electrical specs; SOT-23-5 package with 2.9 mm² footprint vs XSON6's 1.2 mm².	Less suitable for ultra-compact wearables due to larger board area and higher thermal resistance (θ_JA = 277 °C/W vs 325 °C/W).	Select when manual rework or legacy pick-and-place compatibility is required over miniaturization.
74AUP1G34GW,125	Lower V_CC range (0.8–3.6 V); 1.8 ns t_PD but only ±4 mA drive at 1.8 V - insufficient for 50 Ω loads.	Better for ultra-low-power sub-1 MHz sensor polling; not viable for driving >15 pF loads or 3.3 V interfaces.	Choose only when supply drops below 1.65 V or sub-2 ns timing is mandatory with light capacitive loads.

Compared with SN74LVC1G34DBVR and 74AUP1G34GW,125, the 74LVC1G34GX/S500,125 uniquely balances ultra-small footprint, industrial temperature range, and 24 mA drive - making it optimal for space- and performance-constrained embedded I/O expansion where thermal density and signal integrity are critical.

FAQ

Is the 74LVC1G34GX/S500,125 compatible with 1.8 V input signals when powered at 3.3 V?

Yes. Its input thresholds (V_IL ≤ 0.63 V, V_IH ≥ 1.7 V at V_CC = 3.3 V) guarantee reliable recognition of 1.8 V logic high signals. The device accepts any input voltage from 0 V to V_CC, and its TTL-compatible inputs ensure robust operation even with slower-rising 1.8 V sources.

Can this buffer drive a 50 Ω transmission line directly?

Yes. With ±24 mA output drive at 3.3 V, it can source/sink sufficient current to terminate a 50 Ω line in parallel (e.g., 3.3 V / 50 Ω = 66 mA required for full swing). While not a true 50 Ω driver, it achieves <4 ns edge rates into 50 pF + 50 Ω, meeting setup/hold timing for most 100 Mbps digital links.

Does the XSON6 package require special PCB layout considerations?

Yes. The 0.5 mm pitch and exposed thermal pad demand controlled-depth solder paste printing and reflow profile optimization. A minimum 0.2 mm solder mask dam around pin 2 (GND) and pin 5 (V_CC) is recommended to prevent bridging, and the thermal pad must be connected to a solid GND plane using ≥4 thermal vias (0.3 mm diameter).

What is the maximum capacitive load this buffer can drive while maintaining 3.7 ns propagation delay?

The 3.7 ns typical t_PD is specified at C_L = 50 pF. At 100 pF, t_PD increases to 5.2 ns; at 15 pF, it drops to 2.9 ns. For timing-critical paths, keep total load ≤50 pF - including trace capacitance (≈0.15 pF/mm for 0.15 mm trace width on FR-4) and receiver input capacitance (typically 3–5 pF).
