Product details

The 74AHC1G126MDCKTEP: The SC-70-5 package keeps board area small, making this part suitable for signal buffering and enable/disable gating in avionics, satellite, downhole instrumentation, and other high-reliability environments where the wide temperature grade is a selection requirement.

2V to 5.5V supply — one part for 3.3V and 5V domains

At 3.3V the buffer meets the VIH/VIL thresholds of a standard 3.3V CMOS input; at 5V it drives a classic TTL or 5V CMOS load. No level translator is needed when mixing these domains in the same design, as long as the output current stays within the 8mA per pin rating. The 3-state output allows the buffer to be placed on a shared bus without contention when the output enable is driven low.

The product status is Active. Qualify the bill-of-materials with this exact device.

Frequently asked questions

Does 74AHC1G126MDCKTEP support 3.3V logic?

Yes. The supply voltage range of 2V to 5.5V includes 3.3V. At 3.3V the buffer's input thresholds and output drive levels are compatible with standard 3.3V CMOS logic. The 8mA output drive at both high and low levels is sufficient for driving a single CMOS input or a lightly loaded trace.
