Product details

Overview

74LVC1G34GF000 from NXP Semiconductors is a single CMOS buffer IC with Schmitt-trigger inputs, designed for level-shifting and signal conditioning in mixed-voltage systems. It operates from 1.65 V to 5.5 V, accepts 5 V-tolerant inputs, delivers ±24 mA output drive at 3.0 V, and supports industrial temperature range (−40 °C to +125 °C) in XSON6 (SOT891) package. It enables robust interfacing between 3.3 V logic and legacy 5 V peripherals.

For engineers reviewing the 74LVC1G34GF000 datasheet, 74LVC1G34GF000 pinout, 74LVC1G34GF000 application, or 74LVC1G34GF000 equivalent, key selection criteria include its IOFF power-down protection, high noise immunity, sub-5 ns propagation delay at 3.3 V, 5 V input tolerance, and compact 1.0 × 1.0 × 0.5 mm XSON6 footprint-critical for space-constrained I/O expansion and voltage translation designs.

Technical Context

The 74LVC1G34GF000 implements a non-inverting buffer with Schmitt-trigger inputs to tolerate slow-rising signals and suppress noise-induced glitches. Its IOFF circuitry actively disables outputs during power-down, blocking backflow current when VCC = 0 V-enabling hot-swap and partial-power-down system architectures.

It complies with JEDEC standards JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.7 V), and JESD8-B/JESD36 (2.7–3.6 V), and features ESD protection exceeding 2000 V HBM and 200 V MM. Input leakage remains ≤±5 µA across full supply and temperature range.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	1.65 V to 5.5 V - Enables direct operation from 1.8 V, 2.5 V, 3.3 V, or 5 V rails without level shifters.
Input Voltage Tolerance	Up to 5.5 V - Allows safe connection to 5 V logic outputs even when powered from 1.8 V or 2.5 V.
Output Drive Strength	±24 mA at VCC = 3.0 V - Sufficient to drive multiple LVC/LVT inputs or small capacitive loads (≤30 pF) with <5 ns delay.
Propagation Delay	0.5–4.1 ns (VCC = 3.0–3.6 V) - Supports high-speed digital control paths in real-time I/O subsystems.
IOFF Leakage Current	≤±10 µA at VCC = 0 V - Prevents bus contention and power rail coupling during power sequencing or standby.
Operating Temperature	−40 °C to +125 °C - Qualified for under-hood automotive modules, industrial PLC I/O, and telecom line cards.
Input Capacitance	4 pF - Minimizes loading on upstream drivers and preserves signal integrity in high-density routing.

Pinout & Package

XSON6 (SOT891) package: plastic extremely thin small outline, no leads, 6 terminals, body size 1.0 × 1.0 × 0.5 mm. Pin 1 indicator located at lower-left corner below marking code "YN".

Pin/Terminal	Circuit Role	Design Meaning
n.c.	Not connected	No internal connection; must remain unconnected on PCB to avoid parasitic coupling or mechanical stress.
A	Data input	Schmitt-trigger buffered input accepting 0–5.5 V; immune to slow edges and noise up to ±0.8 V hysteresis.
GND	Ground reference	0 V return path for all internal logic and output stages; requires low-inductance local decoupling.
Y	Data output	CMOS push-pull output with rail-to-rail swing; drives loads up to ±24 mA while maintaining VOL ≤ 0.55 V.
n.c.	Not connected	Second unused terminal; electrically isolated and mechanically defined for package symmetry and thermal relief.
VCC	Supply voltage	Primary power rail (1.65–5.5 V); powers all logic and output stages; requires 100 nF ceramic decoupling near pin.

Key Features

Feature	Design Value
5 V tolerant inputs	Enables direct interface with legacy 5 V microcontrollers, sensors, or displays without external resistors or translators.
IOFF partial power-down	Prevents damaging back-current flow when VCC is off-essential for hot-pluggable modules and multi-rail power sequencing.
Schmitt-trigger inputs	Provides >0.8 V hysteresis at 3.3 V, eliminating false triggering from noisy or slow-switching signals like mechanical switches or long traces.
Low dynamic power	CPD = 15 pF enables sub-10 µW dynamic power at 1 MHz/3.3 V-ideal for battery-backed I/O expanders and always-on monitoring nodes.
Wide temperature range	Specified from −40 °C to +125 °C ensures reliable operation in automotive engine compartments and industrial motor drives.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G34DBVR	SOT-23-5 package (2.9 × 1.6 × 1.45 mm); higher thermal resistance; no n.c. pins; same electrical specs.	Less suitable for ultra-dense layouts but easier to rework; lacks dual n.c. pins for mechanical stability in fine-pitch designs.	Select for prototyping or low-volume production where hand-soldering or optical inspection is required.
74AUP1G34GW,125	Lower ICC (0.9 µA typ), slower tpd (6.1 ns min at 3.3 V), identical XSON6 (SOT353) footprint but different pinout (VCC/GND swapped).	Optimized for ultra-low-power always-on sensing; not pin-compatible-requires PCB redesign.	Select only when sub-1 µA static current is mandatory and timing budget allows ≥6 ns delay.

Compared with SN74LVC1G34DBVR, the 74LVC1G34GF000 offers superior board-area efficiency and thermal performance in thermally constrained modules; compared with 74AUP1G34GW,125, it delivers faster response and proven interoperability with 5 V peripherals-making it optimal for mixed-voltage industrial control interfaces.

FAQ

What is the maximum input voltage the 74LVC1G34GF000 can safely accept?

The 74LVC1G34GF000 accepts input voltages up to 5.5 V regardless of VCC level-including when powered down (VCC = 0 V). This 5 V tolerance enables direct connection to legacy 5 V logic families without external clamping or level-shifting circuitry, and is validated per JEDEC JESD8-B compliance.

Does the 74LVC1G34GF000 support partial power-down operation?

Yes, the 74LVC1G34GF000 includes integrated IOFF circuitry that automatically disables the output stage when VCC = 0 V, limiting power-off leakage current to ≤±10 µA. This prevents damaging backflow current into powered-down sections of the system-critical for hot-swap capable designs and multi-rail power sequencing.

What is the propagation delay of the 74LVC1G34GF000 at 3.3 V supply?

At VCC = 3.3 V and −40 °C to +85 °C ambient, the 74LVC1G34GF000 exhibits a typical propagation delay (tpd) of 2.0 ns with a maximum of 4.1 ns. At the extended −40 °C to +125 °C range, maximum tpd increases to 5.2 ns-verified under load conditions of 30 pF and 500 Ω termination.

Is the 74LVC1G34GF000 pin-compatible with other members of the 74LVC1G34 family?

Yes-the 74LVC1G34GF000 shares identical pinout (SOT891: n.c./A/GND/Y/n.c./VCC) with other XSON6 variants including 74LVC1G34GM, GN, and GS. However, it is not pin-compatible with TSSOP5 (74LVC1G34GW) or SC-74A (74LVC1G34GV) packages due to differing terminal count and layout.

What package type and dimensions does the 74LVC1G34GF000 use?

The 74LVC1G34GF000 uses the XSON6 package (JEDEC designation SOT891): a leadless, surface-mount package with six terminals, body dimensions of 1.0 mm × 1.0 mm × 0.5 mm, and a 0.5 mm pitch. Pin 1 is marked by a lower-left corner index area beneath the "YN" top-side marking.
