What are the key features of 74LVC1G240DBVT?
- Single inverting 3-state buffer with 5 V tolerant inputs, enabling direct interface between 3.3 V logic outputs and 5 V legacy bus lines without external protection
- Drives up to 32 mA output current with 3.2 ns typical propagation delay at 3.3 V, supporting high-speed bus driving in compact 5-pin SOT-23 package
- Operates from 1.65 V to 5.5 V supply, making it compatible with 1.8 V, 2.5 V, 3.3 V, and 5 V logic families in mixed-voltage system designs
What is 74LVC1G240DBVT used for?
74LVC1G240DBVT is widely used for signal buffering, bus isolation, and logic level interfacing in microcontroller, FPGA, and DSP systems where a low-power inverting 3-state driver is needed in minimal board space. Its 5 V tolerant inputs and 1.65 V to 5.5 V supply range make it a practical bridge between modern 3.3 V processors and 5 V peripheral buses in consumer, industrial, and embedded computing applications.

Frequently Asked Questions
How much output drive current does 74LVC1G240DBVT provide and at what propagation delay?
74LVC1G240DBVT sources or sinks up to 32 mA of output current, sufficient to drive heavily loaded PCB traces or multiple CMOS inputs simultaneously. Typical propagation delay is 3.2 ns at 3.3 V supply, making it fast enough for SPI, I2C, and general-purpose GPIO buffering in systems clocked up to hundreds of MHz at the input stage.
Can 74LVC1G240DBVT interface 3.3 V microcontroller outputs directly to a 5 V legacy bus?
Yes. The 5 V tolerant input structure allows the device to accept 5 V input signals while powered from 3.3 V, and conversely its output swings to the VCC rail of 1.65 V to 5.5 V, enabling direct voltage translation. This eliminates the need for a separate level-shifter IC in mixed-voltage designs connecting a 3.3 V MCU GPIO to 5 V peripheral buses such as older TTL or CMOS address lines.
For a compact embedded PCB with limited space, what area does the 74LVC1G240DBVT SOT-23 package occupy?
The 5-pin SOT-23 package measures approximately 3 mm × 1.75 mm with 0.95 mm pin pitch, making it one of the smallest available footprints for a buffered output driver. This is ideal for handheld instruments, IoT nodes, and dense multi-layer PCBs where each square millimeter matters. The device operates from 1.65 V to 5.5 V, so no additional supply rail is needed beyond the existing system voltage.
