20-TSSOP, 4.40 mm body width, surface-mount. The 0.173" (4.40 mm) width is a common TSSOP footprint — same land pattern as many 20-pin TSSOP logic parts from TI and NXP. Tube shipping; if the line prefers Tape & Reel, the -CPWR variant is the reeled version of the same die.
ROHS3 compliant. The -CPWR (Tape & Reel) variant is a direct drop-in for reel-fed lines, same silicon.
Yes, it carries ROHS3 compliance.
The die and electrical specifications are identical. The -CPW suffix ships in Tube; the -CPWR suffix ships in Tape & Reel. Choose the reeled variant for automated pick-and-place assembly lines.
No — DS90CP22MT/NOPB is a crosspoint switch with a 1 x 2:2 configuration, not a direct functional replacement for the 8 x 1:1 bus switch topology. The circuit architecture and pinout differ.
