Product details

Quad buffer with 3-state outputs for mixed-voltage buses

Each of the four elements handles one bit, with a supply range of 1.65V to 3.6V, making it suitable for bridging 1.8V, 2.5V, or 3.3V logic domains without external level shifters. The 3-state outputs allow multiple devices to share a common bus by disabling individual channels, which is essential for multiplexed data lines in microcontroller or FPGA interfaces.

The 1.65V to 3.6V supply range covers the standard low-voltage logic rails used in modern embedded systems. At 3.3V, the buffer can drive 24 mA per output, sufficient for CMOS inputs, LED indicators, or short PCB traces. The 125°C ceiling also provides margin for self-heating in densely populated boards.

Frequently asked questions

Is SN74LVC125AD obsolete or active?

No discontinuation or last-time-buy notice has been issued.

What does 3-state output mean for SN74LVC125AD?

Each of the four buffer outputs can be independently disabled to a high-impedance state, allowing multiple devices to share a common bus without contention.

Does SN74LVC125AD have a recommended alternative if unavailable?

The SN74LVC2G17QDCKRQ1 is a functionally similar buffer from the same 74LVC family, but it uses Schmitt-trigger inputs and comes in a different package (SC-70). Verify pin compatibility and input threshold requirements before substituting.
