Product details

Overview

SN74LVC1G07DCKTE4 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 interfaces.

For engineers reviewing the SN74LVC1G07DCKTE4 datasheet, SN74LVC1G07DCKTE4 pinout, SN74LVC1G07DCKTE4 application, or SN74LVC1G07DCKTE4 equivalent, key selection criteria include open-drain drive strength (32mA), I_off support for live insertion, 0.5mm-pitch SC70-5 package compatibility, and 5.5V input tolerance across 1.65–5.5V supply range.

Technical Context

The SN74LVC1G07DCKTE4 implements a single CMOS buffer with true open-drain output architecture, 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 designs.

It operates across –40°C to 125°C ambient temperature in SC70-5 (DCK) package, with input thresholds scaling with V_CC (e.g., VIH = 0.7×V_CC at 4.5–5.5V) and guaranteed VOL ≤ 0.55V at I_OL = 32mA - ensuring reliable low-state signaling under heavy sink loads.

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 without level shifters.
Max Sink Current (I_OL)	32mA at V_CC = 4.5V - enables direct LED driving or robust wired-OR bus termination.
t_pd (max)	4.2ns at V_CC = 3.3V, T_A = –40°C to 85°C - suitable for signal buffering up to ~100MHz clock/data paths.
I_off	±10µA max at V_CC = 0V - prevents damaging current flow during hot-plug or power sequencing events.
Input Voltage Tolerance	Up to 5.5V independent of V_CC - allows safe interfacing with higher-voltage controllers or legacy peripherals.
ESD Rating (HBM)	2000V - exceeds JEDEC JESD22-A114A, supporting handling in standard manufacturing environments.
Package	SC70-5 (DCK), 2.0mm × 2.1mm body, 0.5mm pitch - ultra-compact footprint for high-density PCB layouts.

Pinout & Package

SC70-5 (DCK) package: 2.0mm × 2.1mm body size, 0.5mm lead pitch, 5-terminal surface-mount device with exposed pad not present.

Pin/Terminal	Circuit Role	Design Meaning
1	GND	Ground reference for all internal circuitry and output sink path.
2	A	CMOS-compatible input; accepts 0–5.5V regardless of V_CC value.
3	N.C.	No internal connection - must be left unconnected or tied to GND/V_CC per layout guidelines.
4	Y	Open-drain output; requires external pull-up to define logic HIGH voltage level.
5	V_CC	Power supply input; regulates internal logic and defines output LOW threshold (VOL).

Key Features

Feature	Design Value
Wide V_CC range (1.65–5.5V)	Enables single-bom deployment across multiple voltage rails in mixed-signal systems.
5.5V-tolerant inputs	Eliminates need for external clamping diodes when interfacing with 5V microcontrollers or FPGAs.
I_off protection	Permits safe insertion into powered-backplane systems without risk of latch-up or reverse current damage.
Low ICC (10µA max)	Reduces quiescent power in always-on subsystems such as audio codec control interfaces.

Equivalent & Alternatives

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

SN74LVC1G07DBVT	SOT-23-5 (DBV) package; larger 2.9mm × 2.8mm footprint, same electrical specs and pinout.	Better thermal performance (R_θJA = 357°C/W vs. 371°C/W) but occupies >3× board area.	Select when thermal margin is critical and PCB space permits larger package.
74LVC1G07GW,125	Nexperia SC-70-5 variant; identical function, 32mA sink, but rated only to 125°C (no extended temp option).	Lacks I_off specification in datasheet; not validated for live-insertion use cases.	Choose for cost-sensitive consumer applications where partial-power-down is not required.

Compared with SN74LVC1G07DBVT and 74LVC1G07GW,125, the SN74LVC1G07DCKTE4 uniquely balances ultra-small SC70-5 footprint, full I_off support, and industrial temperature rating - making it optimal for space-constrained, hot-pluggable embedded audio/video systems.

FAQ

What is the maximum sink current supported by the SN74LVC1G07DCKTE4?

The SN74LVC1G07DCKTE4 supports a maximum sink current of 32mA when V_CC = 4.5V, as specified in the Absolute Maximum Ratings table. This value is guaranteed across the full operating temperature range (–40°C to 125°C) and enables direct driving of LEDs or robust wired-OR bus termination without external amplification. The SN74LVC1G07DCKTE4 maintains VOL ≤ 0.55V under this load condition.

Does the SN74LVC1G07DCKTE4 support level translation between different voltage domains?

Yes, the SN74LVC1G07DCKTE4 supports both up-translation and down-translation due to its 5.5V-tolerant inputs and open-drain output architecture. Inputs accept voltages up to 5.5V regardless of V_CC, and the output can be pulled up to any voltage ≤ 5.5V. This allows the SN74LVC1G07DCKTE4 to interface a 1.8V MCU with a 5V peripheral, provided the external pull-up matches the target domain voltage.

What is the purpose of the I_off feature in the SN74LVC1G07DCKTE4?

The I_off feature in the SN74LVC1G07DCKTE4 disables output drivers when V_CC = 0V, limiting leakage current to ±10µA. This prevents back-drive current from externally powered buses into a powered-down system, enabling safe live insertion and partial-power-down operation. For example, the SN74LVC1G07DCKTE4 can remain connected to a 5V I²C bus while its host MCU is in deep sleep mode without violating JEDEC JESD78 latch-up limits.

Which package does the SN74LVC1G07DCKTE4 use, and what are its dimensions?

The SN74LVC1G07DCKTE4 uses the SC70-5 (DCK) package: a 5-pin surface-mount package with 2.0mm × 2.1mm body size and 0.5mm lead pitch. Its compact footprint (0.64mm² active area) saves significant PCB space compared to SOT-23 alternatives, while maintaining compatibility with standard reflow processes and visual inspection workflows. The SN74LVC1G07DCKTE4 pinout matches industry-standard SC70-5 mechanical drawings.

Can the SN74LVC1G07DCKTE4 be used in wired-OR configurations?

Yes, the SN74LVC1G07DCKTE4 is explicitly designed for wired-OR (or active-high wired-AND) configurations due to its open-drain output. Multiple SN74LVC1G07DCKTE4 outputs can share a single pull-up resistor to implement interrupt aggregation, bus arbitration, or fault-signaling networks. The device's guaranteed 32mA sink capability ensures reliable low-state signaling even with multiple devices pulling simultaneously on the same line.
