SN74LVC1G07DCK6 Texas Instruments Integrated Circuit (SOT23 (5-Pin)) In Stock
The SN74LVC1G07DCK6 is a single-channel open-drain buffer from Texas Instruments in the LVC logic family, operating from a 1.65 V to 5.5 V supply with TTL and CMOS-compatible inputs. Its open-drain output can be pulled up to a voltage independent of VCC, enabling level translation from 1.8 V logic up to 5.5 V. Housed in a 5-pin SC-70 package, it suits level shifting, wire-OR bus driving, and signal conditioning in portable and low-power designs.

What are the key features of SN74LVC1G07DCK6?
- Single open-drain buffer enabling output pull-up to voltages independent of supply (up to 5.5 V)
- Wide supply range: 1.65 V to 5.5 V for 1.8 V, 2.5 V, 3.3 V, and 5 V system compatibility
- High output sink current: 32 mA for direct LED or relay driver applications
- Fast propagation delay: typically 3.8 ns at 3.3 V for high-speed signal buffering
- Ultra-compact 5-pin SC-70 package measuring 2.0 mm × 2.1 mm for minimal PCB footprint
- LVC family input hysteresis for clean switching on slow or noisy input signals
What is SN74LVC1G07DCK6 used for?
The SN74LVC1G07DCK6 is commonly used for logic-level translation between a 1.8 V or 3.3 V microcontroller output and a 5 V peripheral by connecting the open-drain output to a 5 V pull-up resistor. It is also used in I2C bus buffering, wire-OR signal combining on shared lines, and as a small-signal open-drain switch for driving indicator LEDs or optocoupler inputs directly from low-voltage MCU GPIO pins.

Frequently Asked Questions
How can the SN74LVC1G07DCK6 translate a 1.8 V logic output to a 5 V compatible signal?
Because the SN74LVC1G07DCK6 has an open-drain output, it can be pulled up to any voltage up to 5.5 V regardless of its own VCC supply. By powering the device from 1.8 V and connecting a 10 kΩ pull-up resistor from the output to a 5 V rail, a 1.8 V input logic high drives the output low (0 V) and a logic low releases it to 5 V, completing a non-inverting level shift from 1.8 V to 5 V signaling.
What output current can the SN74LVC1G07DCK6 sink, and can it drive an LED directly?
The SN74LVC1G07DCK6 open-drain output can sink up to 32 mA at a VOL of 0.55 V maximum. This is sufficient to drive a standard LED with a 5 V pull-up and a current-limiting resistor of approximately 130 Ω (yielding about 30 mA), making it practical to drive indicator LEDs directly from a microcontroller GPIO line without an additional transistor or MOSFET in the circuit.
Over what supply voltage range does the SN74LVC1G07DCK6 operate, and is it compatible with 3.3 V systems?
The SN74LVC1G07DCK6 operates from 1.65 V to 5.5 V, fully covering the 1.8 V, 2.5 V, 3.3 V, and 5 V supply levels common in modern embedded systems. At 3.3 V VCC, the input thresholds are TTL-compatible (VIL = 0.8 V, VIH = 2.0 V), accepting both CMOS and TTL input sources, and the device propagates signals with a typical delay of approximately 4.5 ns.
What package does the SN74LVC1G07DCK6 use, and where is it preferred over a SOIC package?
The SN74LVC1G07DCK6 is packaged in a 5-pin SC-70 (DCK suffix) measuring 2.0 mm × 2.1 mm with 0.65 mm pitch. Compared to a 5-pin SOT-23 at 2.9 mm × 1.6 mm, the SC-70 is smaller and better suited to ultra-compact PCBs in wearables, Bluetooth modules, or mobile accessories where PCB real estate is limited and a single-function logic buffer near a GPIO pin saves routing area.
When is the SN74LVC1G07DCK6 used on an I2C bus, and what pull-up value is recommended?
On an I2C bus, the SN74LVC1G07DCK6 can serve as a bus buffer or re-driver for long PCB traces up to 400 pF capacitance. For a 400 kHz fast-mode I2C bus with 3.3 V pull-up, a 4.7 kΩ pull-up resistor on the output meets the I2C specification for rise time (below 300 ns with 400 pF bus capacitance). For 1.7 MHz fast-mode plus, lowering to 1 kΩ keeps rise times under 120 ns.
