Product details

Overview

SN74LVC1G07DCKT 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 ±24mA drive at 3.3V, supports 5.5V-tolerant I/O, features I_off for live insertion, and achieves 4.2ns max t_pd at 3.3V - used in level translation and wired-OR logic in portable media players and SSDs.

For engineers reviewing the SN74LVC1G07DCKT datasheet, SN74LVC1G07DCKT pinout, SN74LVC1G07DCKT application, or SN74LVC1G07DCKT equivalent, key selection criteria include open-drain sink capability (32mA max), 0.5mm-pitch SC70-5 package compatibility, I_off-enabled partial-power-down support, and 5.5V input tolerance across 1.65–5.5V supply range.

Technical Context

The SN74LVC1G07DCKT implements a single CMOS buffer stage with open-drain output topology, enabling active-low wired-OR and active-high wired-AND bus configurations. Its I_off circuitry actively disables outputs when V_CC = 0V, preventing back-drive current and supporting hot-plug operation.

It operates across –40°C to 125°C ambient temperature (per SC70 package rating), accepts input voltages up to 5.5V independent of V_CC, and maintains specified switching performance (t_pd ≤ 4.7ns) over full industrial temperature range 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 external level shifters.
Max Sink Current (I_OL)	32mA at 4.5V - sufficient to directly drive LEDs, pull-up resistors in I²C buses, or interface with higher-current loads.
Propagation Delay (t_pd)	4.2ns max at 3.3V, 25°C - supports signal integrity in high-speed digital control paths up to ~100MHz.
I_off Current	±10µA max - ensures safe isolation during partial power-down, critical for system-level power sequencing and hot-swap compliance.
Input Voltage Tolerance	Up to 5.5V regardless of V_CC - allows interfacing with legacy 5V peripherals while powered from lower-voltage rails.
ESD Rating (HBM)	2000V - meets JEDEC JESD22-A114 standard, reducing susceptibility to handling damage in manufacturing and field service.

Pinout & Package

SN74LVC1G07DCKT uses the SC70-5 (DCK) package: 2.0mm × 2.1mm body, 0.65mm height, 0.5mm lead pitch, 5-terminal surface-mount configuration.

Pin/Terminal	Circuit Role	Design Meaning
1	GND	Ground reference for all internal circuitry and output sink path; must be low-impedance connection to system ground plane.
2	A	CMOS-compatible input; accepts 0V–5.5V logic levels regardless of V_CC; no external pull-up required for default high state.
3	N.C.	No internal connection - electrically isolated; may be left unconnected or tied to GND for mechanical stability.
4	Y	Open-drain output; requires external pull-up resistor to define high state; sinks current only (no sourcing capability).
5	V_CC	Power supply input; bypass capacitor (0.1µF ceramic) required adjacent to pin to suppress switching noise and ensure stable operation.

Key Features

Feature	Design Value
Open-drain output architecture	Enables wired-OR/AND bus topologies and I²C-compatible bidirectional signaling with external pull-up.
I_off partial-power-down protection	Prevents damaging back-current flow when V_CC is off, supporting hot-plug and dynamic power gating in modular systems.
5.5V-tolerant inputs	Eliminates need for external level translators when interfacing with 5V microcontrollers or sensors while operating on 1.8V/2.5V supplies.
Ultra-small SC70-5 footprint	2.0mm × 2.1mm body size saves PCB area in space-constrained portable electronics like DVCs and tablets.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G07DBVT	SOT-23-5 package (2.9mm × 2.8mm); higher thermal resistance (R_θJA = 357.1°C/W vs. 371.0°C/W); identical electrical specs.	Less space-constrained designs where larger footprint is acceptable; better suited for manual soldering or prototyping.	Select SN74LVC1G07DBVT when board real estate permits larger package and thermal performance margin is prioritized over miniaturization.
74LVC1G07GW,125	SC-70-5 from Nexperia; same pinout and V_CC range; slightly higher max t_pd (5.5ns @ 3.3V); I_off not explicitly specified in public datasheet.	Cost-sensitive consumer applications where full I_off compliance is not required; qualified for automotive AEC-Q100 Grade 2.	Choose 74LVC1G07GW,125 for automotive-qualified alternatives where I_off is secondary to qualification status and cost.

Compared with SN74LVC1G07DBVT and 74LVC1G07GW,125, the SN74LVC1G07DCKT offers the smallest footprint among TI's offerings and explicit I_off validation - making it optimal for ultra-compact, hot-pluggable, and thermally dense portable electronics designs.

FAQ

What is the maximum sink current capability of the SN74LVC1G07DCKT?

The SN74LVC1G07DCKT supports a maximum sink current of 32mA at V_CC = 4.5V, as specified in the Absolute Maximum Ratings table. This value is validated across the full operating temperature range (–40°C to 125°C) and enables direct driving of LEDs, pull-up networks, and moderate-current logic interfaces without external amplification. The SN74LVC1G07DCKT maintains this capability while retaining 5.5V input tolerance and I_off protection.

Does the SN74LVC1G07DCKT support level translation between different voltage domains?

Yes, the SN74LVC1G07DCKT supports bidirectional level translation: its inputs accept voltages up to 5.5V regardless of V_CC, and its open-drain output can be pulled up to any voltage ≤5.5V. When V_CC = 1.8V, the device correctly interprets 3.3V or 5V inputs as logic high, and the Y output reflects that state via external pull-up - enabling seamless interface between 1.8V, 2.5V, 3.3V, and 5V subsystems. This behavior is inherent to the SN74LVC1G07DCKT's architecture and does not require special biasing.

What is the purpose of the N.C. pin on the SN74LVC1G07DCKT SC70-5 package?

The N.C. (No Connection) pin on the SN74LVC1G07DCKT is Pin 3 in the SC70-5 (DCK) package and has no internal bond wire or silicon connection. It is electrically isolated and may be left floating, grounded, or connected to a copper pour for mechanical reinforcement - none of these choices affect electrical performance. This pin exists due to package pinout standardization across TI's 5-pin SC70 logic portfolio and is explicitly documented in the "Pin Functions" table of the SN74LVC1G07DCKT datasheet.

How does the I_off feature function in the SN74LVC1G07DCKT?

The I_off circuitry in the SN74LVC1G07DCKT automatically disables both input and output circuits when V_CC = 0V, limiting leakage current to ±10µA maximum. This prevents back-driving of powered sections of the system through the SN74LVC1G07DCKT's pins during partial power-down or hot-insertion events. The feature is intrinsic to the SN74LVC1G07DCKT's silicon design and requires no external enable/disable control - it activates automatically based on V_CC presence.

What is the recommended bypass capacitor for the SN74LVC1G07DCKT V_CC pin?

A 0.1µF ceramic capacitor is recommended for the SN74LVC1G07DCKT V_CC pin, placed as close as possible to the pin (≤2mm trace length) with low-inductance connection to GND. This value is specified in TI's layout guidelines for single-supply logic devices and effectively filters high-frequency switching noise generated by the SN74LVC1G07DCKT's 4.2ns transitions. For systems with shared V_CC rails, paralleling a 1µF tantalum or X7R MLCC further stabilizes low-frequency supply droop.
