PI3B3257 Multiplexer/Demultiplexer Switches

Diodes Incorporated PI3B3257 Multiplexer/Demultiplexer Switches are 3.3V quad 2:1 Mux/DeMux with three-state output pinout and function compatible with PI74FCT257T, 74F257, and 74ALS/AS/LS257. The Diodes Incorporated switches feature non-zero propagation delay and 5Ω low On-Resistance. The PI3B3257 mux/demux switches are pin-compatible with 74 series 257 logic devices. These switches offer 120mA DC output current and 0.5W power dissipation. The PI3B3257 mux/demux switches operate at -40°C to 85°C ambient temperature range. These switches function with -0.5V to 4.6V supply voltage to ground potential. The PI3B3257 mux/demux switches are ideal for desktop PCs, industrial PCs, medical devices, monitors, STBs, tablet PCs, and TVs.
