Product details

Overview

SN74LVC1G34YZVR from Texas Instruments is a single non-inverting CMOS buffer gate designed for 1.65V–5.5V V_CC operation, delivering ±24mA output drive at 3.3V, 3.5ns max propagation delay (t_pd) at 3.3V/CL=15pF, and I_off support for live insertion and partial power-down. It serves as a level-translating signal conditioner in portable audio interfaces and SSD control paths.

For engineers reviewing the SN74LVC1G34YZVR datasheet, SN74LVC1G34YZVR pinout, SN74LVC1G34YZVR application, or SN74LVC1G34YZVR equivalent, key selection criteria include its ultra-compact YZVR DSBGA-4 package (0.88mm × 0.88mm), 5.5V-tolerant inputs, down-translation capability to V_CC, and guaranteed operation across –40°C to 85°C ambient.

Technical Context

The SN74LVC1G34YZVR implements a single positive-logic buffer (Y = A) using advanced LVC CMOS process technology, enabling rail-to-rail output swing and high noise immunity. Its I_off circuitry actively disables outputs during power-down, preventing back-drive current and supporting hot-plug operation in multi-rail systems.

It operates across a broad V_CC range (1.65V–5.5V) while maintaining consistent input thresholds (VIH/VIL ratios defined per V_CC bin) and low dynamic power (C_pd = 16pF at 3.3V). Input voltage tolerance up to 5.5V enables seamless interfacing with legacy 5V logic without external level shifters.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	1.65V to 5.5V - supports mixed-voltage system interfacing and battery-powered operation down to 1.65V
t_pd (max)	3.5ns at V_CC = 3.3V, CL = 15pF - enables reliable signal buffering up to ~100MHz clock domains
I_OH/I_OL	±24mA at V_CC = 3.3V - drives multiple CMOS loads or LEDs directly without external buffers
I_off	±10μA max at V_CC = 0V - prevents damaging back-current during partial power-down or hot-swap
Input Voltage Tolerance	Up to 5.5V - accepts 5V TTL/CMOS inputs while powered from 1.8V or 3.3V rails
ESD Rating (HBM)	±2kV - meets industrial-grade robustness requirements per JESD22-A114A
Operating Temperature	–40°C to +85°C - qualified for consumer and embedded industrial environments

Pinout & Package

SN74LVC1G34YZVR uses the YZVR variant of Texas Instruments' DSBGA-4 (Die Size Ball Grid Array) package: 0.88mm × 0.88mm body size, 0.5mm pitch, 4 solder balls in 2×2 array. This ultra-compact, bottom-terminal package targets space-constrained portable applications.

Pin/Terminal	Circuit Role	Design Meaning
A	Input	Single logic input accepting 0–5.5V; compatible with 1.65V–5.5V V_CC and tolerant of overvoltage
Y	Output	Non-inverting buffered output; delivers full rail-swing (0V to V_CC) with ±24mA drive at 3.3V
V_CC	Power	Positive supply pin; must be decoupled with 0.1μF capacitor placed adjacent to ball
GND	Ground	Reference return path for all I/O and internal circuitry; requires low-impedance PCB connection

Key Features

Feature	Design Value
Ultra-small DSBGA-4 package	0.88mm × 0.88mm footprint - reduces board area by >70% vs. SOT-23-5, critical for wearables and SSD modules
5.5V-tolerant inputs	Accepts 5V signals while operating from 1.65V–3.3V supplies - eliminates need for discrete level shifters
I_off protection	Enables safe live insertion and partial power-down - prevents back-drive damage when V_CC = 0V
Low ICC (max)	1μA supply current - extends battery life in always-on sensor or status monitoring circuits
High-speed switching	3.5ns t_pd at 3.3V - supports clean signal integrity in USB, PCIe reset, or display interface timing paths

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G17YZVR	Schmitt-trigger input (hysteresis), same YZVR package and V_CC range	Better noise immunity on slow/susceptible signals (e.g., mechanical switch debouncing), but higher input capacitance (5.5pF)	Select SN74LVC1G17YZVR only when input signal edges are slow or noisy; SN74LVC1G34YZVR preferred for clean digital timing paths.
74LVC1G34GW,125	NXP's SOT353-5 package (2.1mm × 1.25mm), same logic function and electrical specs	Larger footprint and different thermal resistance (R_θJA = 303°C/W vs. 130°C/W for YZVR), less suitable for ultra-dense layouts	Choose 74LVC1G34GW,125 only if SOT-353 is already standardized in design; YZVR offers superior thermal performance and miniaturization.

Compared with SN74LVC1G17YZVR and 74LVC1G34GW,125, the SN74LVC1G34YZVR provides optimal trade-off of ultra-small size, lowest thermal resistance, and precise non-inverting buffering-making it ideal for space- and thermally constrained portable electronics where signal fidelity and layout efficiency are critical.

FAQ

What is the maximum operating temperature range for the SN74LVC1G34YZVR?

The SN74LVC1G34YZVR is specified for operation from –40°C to +85°C ambient temperature. This range applies specifically to the YZVR DSBGA-4 package variant and is validated per JEDEC JESD78 latch-up testing and JESD22 reliability standards. Operation beyond this range may compromise parametric performance or long-term reliability.

Does the SN74LVC1G34YZVR support 5V input signals while powered from a 1.8V supply?

Yes, the SN74LVC1G34YZVR supports input voltages up to 5.5V regardless of V_CC level - including when V_CC = 1.8V. This 5V-tolerant input capability is inherent to its LVC process design and allows direct interfacing with legacy 5V logic without external components. The SN74LVC1G34YZVR maintains correct logic interpretation and does not require series resistors or clamping diodes.

What is the recommended bypass capacitor for the SN74LVC1G34YZVR?

A 0.1μF ceramic capacitor is recommended for bypassing the V_CC pin of the SN74LVC1G34YZVR. It must be placed physically adjacent to the V_CC ball with a short, low-inductance connection to the GND ball. For enhanced noise suppression, a parallel 1μF capacitor may be added nearby. This configuration ensures stable supply voltage during fast output transitions and minimizes ground bounce in high-speed switching.

Can the SN74LVC1G34YZVR drive an LED directly?

Yes, the SN74LVC1G34YZVR can drive an LED directly when configured as a low-side switch (LED anode to V_CC, cathode to Y output). At V_CC = 3.3V, it sinks up to 24mA - sufficient for indicator LEDs with appropriate current-limiting resistance. However, for sustained high-current or high-temperature operation, thermal derating per R_θJA = 130°C/W must be observed to keep junction temperature below 150°C.

Is the SN74LVC1G34YZVR pin-compatible with other SN74LVC1G34 package variants?

No - the SN74LVC1G34YZVR (DSBGA-4) has a unique 2×2 ball layout incompatible with 5-pin packages like DBV (SOT-23-5), DCK (SC70-5), or DRL (SOT-5). Its pinout (A, Y, GND, V_CC) differs from 5-pin variants that include an NC ball. PCB redesign is required when substituting YZVR for any 5-ball or 6-ball variant; the SN74LVC1G34YZVR is not a drop-in replacement.
