The narrow body keeps the signal path short, which helps maintain signal integrity at the switch's bandwidth ceiling. The 14-TSSOP footprint is common across the 74CB family, so a single PCB layout can accommodate multiple TI bus switch variants if a second-source or alternate function is needed later. Pin 1 is clearly marked by the chamfer on the package body. ## Industrial temperature range and deployment envelope The junction temperature stays within the silicon limits as long as the ambient stays under 85°C.","metaTitle":"SN74CB3Q3125PWR Bus Switch, 4-Channel, 14-TSSOP, TI","metaDescription":"Texas Instruments SN74CB3Q3125PWR 4-channel bus switch, 2.3-3.6V supply, 14-TSSOP.
