CMOS Bus Switches suit hot-plugging applications.

Pin-compatible with existing TTL parts, 20 bit, dual-port switches operate from supply voltages of 4-5.5 V. They have power-down protection on inputs and outputs and offer latch-up immunity and ESD protection to 2 kV. Off resistance and On resistance, typically rated at 2-25 ohm, maximize isolation when Off and minimize loading when On. Power dissipation is typically 1 Â-µA. Devices are...
