Product details

Overview

SN74LVC1G34YEPR 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 buffer in portable audio and embedded interface paths.

For engineers reviewing the SN74LVC1G34YEPR datasheet, SN74LVC1G34YEPR pinout, SN74LVC1G34YEPR application, or SN74LVC1G34YEPR equivalent, key selection criteria include its ultra-small DPW (X2SON-5) package (0.8mm × 0.8mm), 5.5V-tolerant inputs, down-translation capability to V_CC, and robust ESD protection (2kV HBM).

Technical Context

The SN74LVC1G34YEPR implements the Boolean function Y = A in positive logic with no inversion. Its CMOS architecture enables rail-to-rail output swing and high noise immunity across the full 1.65V–5.5V supply range.

It features I_off circuitry that disables outputs during power-down, preventing back-drive current and enabling hot-plug compatibility. Input voltage tolerance up to 5.5V allows interfacing with higher-voltage logic while operating at lower V_CC, supporting mixed-supply system design.

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 logic domains
t_pd Max	3.5ns at V_CC = 3.3V, CL = 15pF - enables reliable operation up to ~100MHz digital signaling
I_O Drive	±24mA at V_CC = 3.3V - sufficient to directly drive LEDs or fan-out to multiple CMOS inputs
I_off	<±10μA at V_CC = 0V - ensures safe isolation during partial power-down or hot-swap events
Input Voltage Tolerance	Up to 5.5V independent of V_CC - allows 5V-tolerant input even when V_CC = 1.8V
ESD Rating (HBM)	±2000V - exceeds JEDEC JESD22-A114A, suitable for handheld and consumer assembly environments
I_CC Max	10μA at T_A = 85°C - enables ultra-low static power in battery-powered portable systems

Pinout & Package

SN74LVC1G34YEPR is packaged in the DPW (X2SON-5) variant: 0.8mm × 0.8mm body, 0.5mm pitch, 5-terminal ultra-thin leadless package with wettable flanks for automated optical inspection.

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 digital input accepting 0–5.5V; performs non-inverting buffering
3	GND	Primary ground reference for logic levels and output current sinking
4	Output (Y)	Push-pull CMOS output capable of sourcing/sinking ±24mA at 3.3V
5	V_CC	Power supply input; regulates internal logic thresholds and output drive strength

Key Features

Feature	Design Value
Ultra-small DPW package	0.64mm² footprint (0.8mm × 0.8mm) - saves PCB area in space-constrained portable designs
5.5V-tolerant inputs	Accepts input voltages beyond V_CC up to 5.5V - eliminates need for external level shifters in mixed-voltage systems
I_off protection	Enables live insertion and partial power-down without back-drive damage - critical for modular or hot-swap subsystems
Low dynamic power	C_pd = 16pF at 3.3V - minimizes switching current and reduces total system power at high frequencies
High ESD robustness	2kV HBM, 200V MM, 1kV CDM - improves manufacturing yield and field reliability in consumer electronics

FAQ

What is the maximum operating temperature for SN74LVC1G34YEPR?

The SN74LVC1G34YEPR is rated for operation from –40°C to +85°C ambient temperature when used in the DPW (X2SON-5) package. This range is specified in the Recommended Operating Conditions table of the official datasheet and aligns with commercial-grade applications including portable audio and embedded PCs.

Does SN74LVC1G34YEPR support 5V logic inputs while powered at 3.3V?

Yes, SN74LVC1G34YEPR supports input voltages up to 5.5V regardless of V_CC level. When powered at 3.3V, it safely accepts 5V-tolerant inputs - a key feature enabling level translation without external components in mixed-supply systems.

What is the purpose of the N.C. pin on SN74LVC1G34YEPR?

The N.C. (No Connection) pin on SN74LVC1G34YEPR is an unused die pad with no internal bond wire or circuit connection. Per TI's layout guidance, it may be left floating or tied to GND for mechanical stability - it has no electrical function and must not be connected to V_CC or signal nets.

Can SN74LVC1G34YEPR drive an LED directly?

Yes, SN74LVC1G34YEPR can drive standard indicator LEDs directly: at V_CC = 3.3V, its ±24mA output drive meets typical LED forward current requirements (5–20mA), and its VOL ≤ 0.55V ensures sufficient voltage headroom for common red/green/yellow LEDs.

Is SN74LVC1G34YEPR pin-compatible with other 5-pin logic buffers in DPW package?

SN74LVC1G34YEPR uses the standard DPW (X2SON-5) pinout (Pin 1=N.C., Pin 2=A, Pin 3=GND, Pin 4=Y, Pin 5=V_CC). It is pin-compatible with other TI LVC single-gate devices in the same package, such as SN74LVC1G07YEPR and SN74LVC1G17YEPR, enabling drop-in functional substitution where logic type permits.
