Applications
The 74LVC1G240DCKTG4 is widely used in portable electronics and IoT devices where space is at a premium and mixed-voltage logic interfacing is required. Its 3-state output makes it ideal for bus isolation in microcontroller systems, data buffers in handheld equipment, and signal conditioning in low-power communication interfaces. It is also commonly employed in level-shifting applications between 1.8V, 2.5V, 3.3V, and 5V logic domains.

Frequently Asked Questions
What is the supply voltage range of the 74LVC1G240DCKTG4?
The 74LVC1G240DCKTG4 operates over a wide supply voltage range of 1.65V to 5.5V, making it suitable for 1.8V, 2.5V, 3.3V, and 5V logic systems. This flexibility allows the device to be used across a broad range of modern microcontroller and FPGA-based designs without additional regulation.
How does the output enable pin work on the 74LVC1G240DCKTG4?
The 74LVC1G240DCKTG4 uses an active-low output enable (OE#) control pin. When OE# is driven LOW, the output is enabled and the inverted logic signal passes through. When OE# is HIGH, the output enters a high-impedance (3-state) condition, effectively disconnecting the driver from the bus and allowing multiple devices to share the same line.
What package does the 74LVC1G240DCKTG4 come in, and what are its dimensions?
The 74LVC1G240DCKTG4 is housed in a 5-pin SC-70 package (also known as SOT323 or DCK), which measures approximately 2.0mm × 1.25mm. This ultra-small form factor is optimized for portable, space-constrained applications such as wearables, smartphones, and compact IoT sensor boards.
Can the 74LVC1G240DCKTG4 replace other single-channel inverting bus drivers?
Yes, the 74LVC1G240DCKTG4 is pin-compatible and functionally equivalent to other single-gate LVC-family inverting 3-state buffers such as the 74LVC1G240 in SOT23-5. It can also serve as a drop-in replacement for SN74LVC1G240 devices from Texas Instruments in the same SC-70 package, provided the supply voltage and output drive requirements are met.
What is the typical propagation delay of the 74LVC1G240DCKTG4?
At 3.3V supply, the 74LVC1G240DCKTG4 typically exhibits a propagation delay of around 4.3ns (t_pd), enabling high-speed signal buffering in applications up to hundreds of megahertz. At 5V, this delay decreases further, making the device well-suited for fast digital logic and bus management in timing-sensitive designs.
