Product details

Single inverting buffer with 3-state — what it does for the bus

The 3-state output means the pin goes high-impedance when the output-enable is deasserted — useful for bus arbitration or shared interrupt lines where only one driver talks at a time.

Output drive — 32 mA symmetrical

Symmetrical 32 mA source and sink drive handles typical GPIO loads, LED indicators, or driving the input of a downstream gate. The 3-state output also means the part can be used in wired-OR or wired-AND configurations with external pull-ups.

Lifecycle — active, no last-time-buy pressure

No last-time-buy risk for ongoing production BOMs.

Frequently asked questions

Is 74LVC1G240DBVTG4 inverting or non-inverting?

It is an inverting buffer. A logic high on the input produces a logic low on the output, and vice versa.

What is the difference between 74LVC1G240 and 74LVC1G125?

The 74LVC1G240 is an inverting buffer; the 74LVC1G125 is a non-inverting buffer. Both are single-channel 3-state buffers in the same 74LVC family and share the same supply range and package options. Choose the 240 when you need inversion, the 125 when you do not.
