The QS3253S1G is a high-speed CMOS TTL-compatible dual 4:1 multiplexer/ demultiplexer with 3-state outputs. The QS3253S1G is function and pinout compatible version of the 74F253, 74FCT253, and the 74ALS/AS/ LS253 dual 4:1 multiplexers. The low ON resistance of the QS3253S1G allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. The QS3253S1G operates at -40C to +85C.
