Product details

Overview

SN74LVC1G34YZTR 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 in portable audio systems.

For engineers reviewing the SN74LVC1G34YZTR datasheet, SN74LVC1G34YZTR pinout, SN74LVC1G34YZTR application, or SN74LVC1G34YZTR equivalent, this page delivers verified package mapping (DPW, 0.8mm × 0.8mm), confirmed logic function (Y = A), absolute maximum ratings (–0.5V to 6.5V on all pins), thermal metrics (R_θJA = 340°C/W), and ESD robustness (2kV HBM).

Technical Context

This device implements a single positive-logic buffer (Y = A) with rail-to-rail input tolerance up to 5.5V and down-translation capability to V_CC. Its I_off circuitry actively disables outputs during partial power-down, preventing back-drive current and enabling hot-plug compatibility.

It operates across –40°C to 85°C (DSBGA packages) with guaranteed switching performance at 1.65V–5.5V supply, supports capacitive loads ≤50pF, and maintains low static ICC ≤10μA while delivering high-speed signal integrity via controlled rise/fall rates (10ns/V at 3.3V).

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	1.65V to 5.5V - Enables direct interface with 1.8V, 2.5V, 3.3V, and 5V logic domains without level shifters.
t_pd Max	3.5ns at 3.3V/CL=15pF - Supports signal integrity in high-speed digital paths up to ~100MHz.
I_O Drive	±24mA at 3.3V - Sufficient to directly drive LEDs, multiple CMOS inputs, or moderate capacitive loads.
I_CC Max	10μA - Ensures ultra-low quiescent power in battery-powered portable devices.
I_off	±10μA - Enables safe live insertion and partial power-down without bus contention or latch-up risk.
ESD Rating	2kV HBM - Meets industrial-grade electrostatic discharge immunity per JESD22-A114A.
Input Voltage Range	–0.5V to 5.5V - Accepts overvoltage inputs beyond V_CC, simplifying mixed-voltage system interfacing.

Pinout & Package

SN74LVC1G34YZTR uses the DPW (X2SON-5) package: 0.80mm × 0.80mm body, 0.5mm pitch, 5-terminal configuration with exposed pad not connected internally.

Pin/Terminal	Circuit Role	Design Meaning
1	No internal connection (N.C.)	Unused terminal; must be left floating or tied to GND/V_CC per layout best practice - no electrical function.
2	Input (A)	CMOS-compatible input accepting voltages up to 5.5V; defines logic state passed to output Y.
3	GND	Reference ground for all internal circuitry and output sink current path.
4	Output (Y)	Non-inverting buffered output capable of sourcing/sinking ±24mA at 3.3V with rail-aligned VOH/VOL.
5	V_CC	Power supply input; sets logic thresholds, output voltage swing, and drive strength - must be decoupled with 0.1μF capacitor.

Key Features

Feature	Design Value
Ultra-small DPW package	0.64mm² footprint (0.8mm × 0.8mm) - enables space-constrained PCB layouts in portable audio and SSD applications.
V_CC-independent input tolerance	Accepts inputs up to 5.5V regardless of V_CC (1.65V–5.5V) - eliminates need for external level-shifting in mixed-supply systems.
Live-insertion support	I_off limits leakage to ±10μA when V_CC = 0 - prevents back-drive damage during hot-swap operations in docking stations.
High-speed low-power logic	3.5ns t_pd with only 10μA ICC at 3.3V - achieves timing-critical buffering without compromising battery life.
Robust ESD protection	2kV HBM, 1kV CDM - exceeds JEDEC standards for handling and board-level reliability in consumer manufacturing.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
74LVC1G34GW,125 (Nexperia)	Same logic function and 1.65V–5.5V V_CC, but uses SOT353 (SC-70) package (2.0mm × 2.1mm); R_θJA = 303°C/W; t_pd = 3.7ns @ 3.3V.	Less suitable for ultra-dense portable layouts due to 3.2× larger footprint than DPW; identical functional behavior in non-space-constrained designs.	Select when SC-70 hand-solderability or legacy footprint compatibility is required over minimal area.
NC7SZ34P5X (ON Semiconductor)	Same 1.65V–5.5V range and Y=A function, but uses SOT-953 (1.0mm × 1.0mm); t_pd = 4.5ns @ 3.3V; I_O = ±24mA; no I_off specification provided.	Lacks documented I_off support - unsuitable for live-insertion or partial-power-down use cases like docking stations.	Select only for fixed-power systems where hot-swap is not required and slightly relaxed timing is acceptable.

Compared with 74LVC1G34GW,125 and NC7SZ34P5X, SN74LVC1G34YZTR uniquely combines the smallest available footprint (DPW), guaranteed I_off, and fastest t_pd - making it optimal for space- and power-sensitive portable audio and SSD control interfaces.

FAQ

What is the maximum operating temperature for SN74LVC1G34YZTR?

The SN74LVC1G34YZTR is rated for operation from –40°C to +85°C ambient temperature when packaged in the DPW (X2SON-5) variant. This range is specified in the Recommended Operating Conditions table and aligns with its DSBGA package thermal characteristics (R_θJA = 340°C/W). Exceeding 85°C ambient may violate junction temperature limits unless board-level thermal design compensates accordingly.

Does SN74LVC1G34YZTR support 5V-tolerant inputs when powered from 1.8V?

Yes, SN74LVC1G34YZTR supports input voltages up to 5.5V independent of V_CC, including when V_CC = 1.8V. This is explicitly confirmed in the Recommended Operating Conditions and Absolute Maximum Ratings sections. The device performs down-translation, allowing safe interfacing between higher-voltage peripherals and lower-voltage controllers without external components.

What is the purpose of the N.C. pin on SN74LVC1G34YZTR?

The N.C. (No internal connection) pin on SN74LVC1G34YZTR is a mechanical placeholder with no electrical function. Per TI's DPW package documentation, it must be left unconnected - neither tied to V_CC nor GND - to avoid unintended parasitic coupling. Its presence accommodates standardized die attach and wire bonding in the X2SON-5 layout.

Can SN74LVC1G34YZTR drive an LED directly?

Yes, SN74LVC1G34YZTR can drive an LED directly when configured as a low-side switch (LED anode to V_CC, cathode to Y output). At 3.3V V_CC, it sinks up to 24mA - sufficient for indicator LEDs. Ensure current-limiting resistance is calculated using VOL ≈ 0.55V and forward voltage drop; also verify total power dissipation remains within thermal limits for continuous operation.

Is SN74LVC1G34YZTR pin-compatible with other SN74LVC1G34 package variants?

No, SN74LVC1G34YZTR (DPW package) is not pin-compatible with other SN74LVC1G34 variants such as DBV (SOT-23), DCK (SC70), or YZP (DSBGA-5). Pin 1 is N.C. in DPW but functions as V_CC in DBV/DCK, and pin counts differ across packages (DPW = 5-pin, DSF = 6-pin). Board layout must be specific to the DPW footprint.
