ECL100 16X4 SRAM — what it is and where it fits
100145DCQR is an ECL100 16X4 SRAM — a 64-bit static RAM organized as 16 words of 4 bits, using emitter-coupled logic (ECL) for high-speed cache or scratchpad memory in digital systems where propagation delay matters more than power. The Bulk package means it ships loose, not on tape-and-reel — typical for low-volume production runs or bench prototypes where the pick-and-place feeder count isn't a constraint.
Lifecycle and compliance
RoHS non-compliant — the lead finish or die-attach material contains lead. This blocks use in EU RoHS-exempt categories unless an exemption applies (e.g., high-reliability server/storage where leaded solder joints are still permitted).
