Product details

The Toshiba 74LCX126FT is a quad non-inverting buffer with independent 3-state outputs, built in the 74LCX series. Each of the four buffers can sink or source 24 mA, enough to drive a handful of CMOS loads or a short ribbon cable.

Industrial temperature and active lifecycle

ROHS3 compliance is confirmed, which simplifies EU and RoHS-regulated market shipments.

The 24 mA output drive per channel is a practical figure: it can switch the gate capacitance of several downstream logic inputs or a handful of LEDs, but it will not drive a long backplane trace or a 50 Ω terminated line. For a typical 3.3 V CMOS bus with 10-15 pF load per node, the rise time stays clean at a few nanoseconds. If your design needs to fan out to more than eight standard loads, plan on buffering the output or using a bus-hold variant. The 3-state control per channel (active-high output enable on each buffer) lets you isolate sections of a shared data bus during power sequencing or sleep modes.

Frequently asked questions

Is 74LCX126FT compatible with 3.3V logic?

Yes. Inputs are 5 V tolerant when VCC is 3.3 V, allowing it to interface with legacy 5 V signals without external clamping.
