AEC-Q100 buffer for automotive signal conditioning
The Texas Instruments CLVC244AQDWRG4Q1 is an automotive-grade, AEC-Q100 qualified, non-inverting buffer with 3-state outputs from the 74LVC family. This part is specified for the under-hood and chassis-domain environments where standard commercial logic would drift out of spec or fail entirely.
It is not a bus-holder or line-driver for long backplanes; keep the fanout under eight standard loads per output to maintain the noise margin at 125°C.
Three-state control and supply flexibility
The 3-state outputs allow multiple buffers to share a common data bus without contention — the output enable pins are per-element, giving granular control. The 1.65V to 3.6V supply range means it can run directly from a single Li-ion cell or a regulated 1.8V core rail, eliminating a level translator in mixed-voltage designs.
It is an automotive-qualified variant, so the PCN/EOL notice cycle on the standard 74LVC244 does not directly apply — TI typically notifies separately for the Q1 suffix.
