Dual buffer with 3-state bus control
The TC7WT125FU,LF is a dual non-inverting buffer with independent 3-state outputs, each controlled by its own output enable pin. Each buffer sinks or sources 6mA at the output, sufficient to drive a standard CMOS load or a single TTL gate input. The 3-state feature lets multiple outputs share a common bus line without contention — the output goes high-impedance when the enable pin is deasserted.
8-SSOP footprint and board fit
The narrow pitch keeps the PCB footprint small — useful for dense mixed-signal boards where logic buffers are placed near the edge connector or the bus transceiver. The supply voltage tolerance of 4.5V to 5.5V means it works with a regulated 5V rail that may droop under load or rise during a hot-swap event.
