4 Channel 2:1 Switch BL3257 BL3257 Description BL3257 is a quad single pole/double throw high-speed CMOS TTL-compatible bus switch. The low on resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. Also this device has exceptionally high current capability, which is far greater than most analog switches offered today. A single 5V supply is all that is required for operation. Applications • Set Top Boxes .
