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. ## Lifecycle and sourcing ROHS3 compliant. The -CPWR (Tape & Reel) variant is a direct drop-in for reel-fed lines, same silicon.","metaTitle":"SN74CBT6845CPW Bus Switch, 8 x 1:1, 20-TSSOP","metaDescription":"TI SN74CBT6845CPW bus switch, 8 x 1:1 circuit, 4.5V-5.5V supply, industrial temp -40°C to 85°C, 20-TSSOP.
