MUX/DEMUX Switch Has -2V UHC Protection

The FSTU3257 is a quad 2:1, high-speed CMOS TTL-compatible multiplexer/demultiplexer bus switch that includes undershoot-hardened circuitry (UHC) that senses undershoot levels up to -2V. The patented UHC feature prevents the turn-on of embedded parasitic bipolar elements. This ensures against momentary loss of isolation and data corruption.
The device features low power consumption and low on resistance, as well as a slow output enable to prevent signal disruption. Other features include soft enable turn on to minimize bus-to-bus sharing during enable, a 4 ohm switch connection between two ports, control inputs compatible with TTL levels, and zero bounce in flow-through mode.
The devices are available in 16-pin QSOP and TSSOP packages and are priced at $0.40 each/10,000.
