Product details

Overview

SN74LVC1G07DRY2 from Texas Instruments is a single non-inverting buffer/driver with open-drain output, designed for 1.65V–5.5V V_CC operation. It delivers 32mA sink current at 4.5V, supports 5.5V-tolerant inputs/outputs, and achieves 4.2ns max propagation delay at 3.3V - enabling wired-OR logic and level translation in space-constrained consumer audio and embedded interfaces.

For engineers reviewing the SN74LVC1G07DRY2 datasheet, SN74LVC1G07DRY2 pinout, SN74LVC1G07DRY2 application, or SN74LVC1G07DRY2 equivalent, key selection criteria include open-drain drive strength (32mA), I_off support for live insertion, 0.5mm-pitch 6-pin USON package footprint (1.45mm × 1.0mm), and ±24mA output drive at 3.3V.

Technical Context

The SN74LVC1G07DRY2 implements a single CMOS buffer stage with open-drain output topology, requiring an external pull-up resistor to define high-level voltage. Its I_off circuitry actively disables outputs when V_CC = 0V, preventing back-drive current and enabling partial-power-down system architectures.

It operates across –40°C to +125°C ambient temperature (per DRY package rating), supports voltage translation both up and down (e.g., 1.8V input to 3.3V bus), and maintains 5.5V input tolerance independent of V_CC, allowing interoperability with higher-voltage legacy logic domains.

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 families without level shifters
Max Sink Current (I_OL)	32mA at V_CC = 4.5V - sufficient to drive LEDs, MOSFET gates, or multiple standard-load TTL inputs
t_pd (max)	4.2ns at V_CC = 3.3V - supports signal integrity in sub-100MHz digital control paths
I_off	<±10µA at V_CC = 0V - ensures safe hot-plug operation and prevents back-current during power sequencing
Input Tolerance	0V to 5.5V - allows inputs to exceed V_CC, critical for mixed-voltage bus interfacing
ESD Rating (HBM)	2000V - meets industrial-grade robustness requirements per JESD22-A114
Package	USON-6 (DRY), 1.45mm × 1.0mm body - ultra-compact footprint for high-density PCB layouts

Pinout & Package

SN74LVC1G07DRY2 uses a 6-pin USON (DRY) package with wettable flanks, 0.5mm pitch, and 1.45mm × 1.0mm body size. Pin 1 is marked by a beveled corner; pins 1–3 run along one long edge, pins 4–6 along the opposite edge.

Pin/Terminal	Circuit Role	Design Meaning
1	Input (A)	CMOS-compatible digital input; accepts 0–5.5V regardless of V_CC
2	No Connect (N.C.)	Internally unconnected; must be left floating or tied to GND for mechanical stability
3	GND	Ground reference for all internal circuitry and I/O; requires low-inductance connection to system ground plane
4	Output (Y)	Open-drain NMOS output; sinks current only - external pull-up required for logic-high state
5	N.C.	Internally unconnected; no electrical function; may be used as thermal pad anchor if soldered
6	V_CC	Power supply input; bypass capacitor (0.1µF) required within 2mm for noise suppression

Key Features

Feature	Design Value
Open-drain output	Enables wired-OR logic, I²C bus compatibility, and flexible voltage-level pull-up configuration
I_off protection	Prevents damaging current flow during power-down or hot-swap events, supporting robust system power sequencing
5.5V input tolerance	Eliminates need for external clamping diodes when interfacing with 5V peripherals on lower-V_CC systems
Ultra-small USON-6 package	Reduces board area by >50% vs. SOT-23-5 while maintaining manufacturability on standard 0.5mm-pitch reflow lines
Low ICC (10µA max)	Minimizes quiescent power in always-on subsystems such as wake-on-event detection or battery-backed status indicators

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G07DBVR	SOT-23-5 package (2.9mm × 1.6mm body); 5-pin; no N.C. pins; same electrical specs	Larger footprint; less suitable for ultra-dense layouts; easier manual rework	Select when board space permits and hand-soldering or test probe access is prioritized over miniaturization
SN74LVC1G07DPWR	X2SON-5 package (0.8mm × 0.8mm); 5-pin; no N.C. pins; identical performance and I_off	Smaller than DRY but lacks pin 2/5 N.C. terminals; slightly lower thermal resistance (R_θJA = 130°C/W)	Select when minimal footprint is critical and thermal load is light; verify layout compatibility with 0.4mm pitch

Compared with SN74LVC1G07DBVR and SN74LVC1G07DPWR, SN74LVC1G07DRY2 offers a balanced trade-off: smaller than SOT-23 yet larger than X2SON, with two N.C. pins aiding mechanical anchoring and thermal relief in fine-pitch automated assembly.

FAQ

What is the maximum sink current capability of the SN74LVC1G07DRY2?

The SN74LVC1G07DRY2 provides a maximum sink current (I_OL) of 32mA when V_CC = 4.5V, as specified in the Absolute Maximum Ratings table. This value is validated across –40°C to +125°C and supports direct driving of LEDs, small relays, or MOSFET gates without external amplification. The SN74LVC1G07DRY2 maintains 24mA sink capability at 3.3V, making it suitable for mainstream low-voltage logic interfacing.

Does the SN74LVC1G07DRY2 support level translation between different supply voltages?

Yes, the SN74LVC1G07DRY2 supports both up-translation and down-translation due to its 5.5V-tolerant inputs and open-drain output architecture. For example, a 1.8V microcontroller can drive the A input while the Y output pulls down against a 3.3V or 5V pull-up resistor. The SN74LVC1G07DRY2 does not require matching input/output voltage domains, enabling seamless integration across mixed-supply systems without additional level-shifting components.

How does the I_off feature function in the SN74LVC1G07DRY2?

The I_off circuitry in the SN74LVC1G07DRY2 disables all output paths when V_CC = 0V, limiting leakage current to ±10µA. This prevents back-driving current from live system buses into an unpowered device - critical for hot-swap applications like modular SSDs or field-replaceable I/O cards. The SN74LVC1G07DRY2 maintains this protection across its full operating temperature range and is verified per JESD78 Class II latch-up standards.

What is the recommended bypass capacitor for the SN74LVC1G07DRY2 V_CC pin?

A 0.1µF ceramic capacitor placed within 2mm of the SN74LVC1G07DRY2 V_CC pin and GND is recommended to suppress high-frequency switching noise and stabilize supply voltage during output transitions. For systems with significant power rail noise, paralleling a 1µF capacitor improves low-frequency decoupling. The SN74LVC1G07DRY2's low ICC (10µA max) reduces average current demand, but fast edge rates (enabled by 4.2ns t_pd) necessitate effective local decoupling to prevent ground bounce.

Can the NC pins on the SN74LVC1G07DRY2 be connected to ground or left floating?

The two NC pins (pins 2 and 5) on the SN74LVC1G07DRY2 are internally unconnected and may be left floating per TI's datasheet guidance. However, tying them to GND improves mechanical reliability during reflow and enhances thermal dissipation in high-power-density layouts. Neither connection affects electrical performance, and the SN74LVC1G07DRY2 functionality remains unchanged whether NC pins are floated or grounded - confirmed across all production lots and temperature grades.
