Product details

Overview

SN74LVC1G34 from Texas Instruments is a single non-inverting CMOS buffer gate designed for 1.65V to 5.5V V_CC operation, performing Y = A logic with 3.5ns max propagation delay at 3.3V, ±24mA output drive, and I_off support for live insertion-used in portable audio signal routing and level translation between mixed-voltage subsystems.

For engineers reviewing the SN74LVC1G34 datasheet, SN74LVC1G34 pinout, SN74LVC1G34 application, or SN74LVC1G34 equivalent, this page delivers verified package mapping (USON-6 DRY), confirmed electrical specs (V_CC range, t_pd, I_OH/I_OL), thermal metrics (R_θJA = 439°C/W), and real-world use cases in SSD, tablet, and AV receiver designs.

Technical Context

The SN74LVC1G34 implements a single-stage CMOS buffer with rail-to-rail input tolerance up to 5.5V and down-translation capability to V_CC, enabling interoperability across 1.8V, 2.5V, 3.3V, and 5V logic domains. Its I_off circuitry actively disables outputs during partial power-down, preventing back-drive current into powered-down sections.

It operates across –40°C to 125°C (for non-DSBGA packages) with guaranteed switching performance at CL = 15pF and CL = 50pF loads, supporting high-speed digital interfaces up to 100MHz while maintaining sub-1μA static ICC and robust ESD protection (2kV HBM, 1kV CDM).

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	1.65V to 5.5V - supports direct interface with 1.8V, 2.5V, 3.3V, and 5V systems without level shifters
Max t_pd	3.5ns at 3.3V, CL = 15pF - enables reliable timing in ≤100MHz digital control paths
Output Drive	±24mA at 3.3V - sufficient to directly drive LEDs, multiple CMOS inputs, or short PCB traces
I_off	<±10μA - ensures safe live insertion and prevents back-current when V_CC = 0V
Input Voltage Tolerance	–0.5V to 5.5V - accepts 5V-tolerant inputs even when V_CC = 1.65V, enabling voltage translation
ICC (max)	10μA - ultra-low static power ideal for battery-powered portable devices
ESD Rating (HBM)	±2kV - exceeds JEDEC JESD22-A114A, suitable for handheld consumer assembly

Pinout & Package

SN74LVC1G34DRYR uses a 6-pin USON (Ultra Thin Small Outline No-lead) package, 1.45mm × 1.00mm body size, 0.5mm pitch, wettable flank terminals for automated optical inspection. Thermal resistance R_θJA = 439°C/W reflects its compact footprint and low-power operation.

Pin/Terminal	Circuit Role	Design Meaning
1	No internal connection (N.C.)	Unused pad; must be left floating or grounded per layout guidelines-no electrical function
2	Input (A)	CMOS-compatible input accepting –0.5V to 5.5V; requires termination to V_CC or GND if unused
3	GND	Primary ground reference; sinks total output current + ICC; must be low-impedance
4	Output (Y)	Push-pull CMOS output capable of ±24mA drive; not 5V-tolerant in high state
5	V_CC	Power supply input (1.65–5.5V); requires local 0.1μF bypass capacitor placed adjacent to pin
6	No internal connection (N.C.)	Unused pad; no internal bond wire; electrically isolated

Key Features

Feature	Design Value
5V-tolerant inputs	Accepts up to 5.5V regardless of V_CC, enabling seamless interfacing with legacy 5V controllers
I_off partial power-down	Prevents destructive current flow during hot-plug or asymmetric power sequencing in multi-rail systems
Ultra-small USON-6 package	1.45mm × 1.00mm footprint saves >60% board area vs. SOT-23-5, critical for space-constrained tablets and SSDs
Low dynamic power	C_pd = 16pF at 3.3V enables <1mW operation at 10MHz, extending battery life in portable audio
Guaranteed operation to 125°C	Validated for industrial-temperature applications in telecom AC/DC supplies and embedded PCs

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
74LVC1G17GW,125	Schmitt-trigger input (hysteresis), same USON-6 package, identical V_CC and drive specs	Better noise immunity in noisy environments (e.g., motor-driven AV receivers), but higher input threshold uncertainty	Select when input signals have slow edges or high EMI; avoid if precise logic thresholds required
NC7SZ17P5X	Same Schmitt-trigger function, SC70-5 package (2.0mm × 2.1mm), 3.5ns t_pd at 3.3V, ±24mA drive	Larger footprint than DRYR; lacks I_off support - unsuitable for hot-swap or partial power-down	Choose only for legacy SC70 layouts; not recommended where live insertion or rail independence is needed

FAQ

What is the maximum operating temperature for SN74LVC1G34DRYR?

The SN74LVC1G34DRYR is rated for operation from –40°C to 125°C ambient temperature, validated per JEDEC JESD78 Class II latch-up testing and supported by thermal metrics including R_θJA = 439°C/W. This specification applies to all packages except DSBGA variants, which are limited to 85°C.

Does SN74LVC1G34DRYR support 5V input signals when powered at 1.8V?

Yes, SN74LVC1G34DRYR supports input voltages up to 5.5V regardless of V_CC level-including at 1.8V operation-enabling true 5V-to-1.8V level translation without external components. This is explicitly guaranteed in the Recommended Operating Conditions table under VI (input voltage) limits.

Can SN74LVC1G34DRYR drive an LED directly?

Yes, SN74LVC1G34DRYR can drive an LED directly: at 3.3V V_CC, it delivers up to 24mA sink/source current, sufficient for indicator LEDs with appropriate series resistance. The device's VOL ≤ 0.55V at I_OL = 24mA ensures low forward-voltage drop and minimal power loss in the buffer.

Is SN74LVC1G34DRYR pin-compatible with other 6-pin USON logic gates?

No-SN74LVC1G34DRYR has a unique 6-pin USON pinout (N.C./A/GND/Y/V_CC/N.C.) that differs from standard 6-pin logic gates like inverters or dual buffers. Pin compatibility cannot be assumed; layout must follow the DRY-specific mechanical drawing (SLMS295) and Table 4-1 pin functions.

What decoupling capacitance is recommended for SN74LVC1G34DRYR?

A 0.1μF ceramic capacitor is recommended for SN74LVC1G34DRYR, placed as close as possible between V_CC and GND pins. TI's Layout Guidelines specify mounting directly adjacent to the package with short, wide traces and an unbroken ground plane beneath-critical for maintaining signal integrity and minimizing switching noise in high-speed applications.
