QS3251S1G

QS3251S1G FEATURES:

• Enhanced N channel FET with no inherent diode to Vcc • 5ΩΩΩΩΩ bidirectional switches connect inputs to outputs • Pin compatible with the 74F251, 74FCT251, and 74FCT251T • Zero propagation delay, zero ground bounce • Undershoot clamp diodes on all switch and control inputs • TTL-compatible control inputs • Available in SOIC and QSOP packages

QS3251S1G DESCRIPTION:

The QS3251 is a high-speed CMOS TTL-compatible 8:1 multiplexer/demultiplexer. The QS3251 has 3-state outputs. The QS3251 is a functionand pinout compatible version of the 74F251, 74FCT251 and the 74ALS/AS/LS251 8:1 multiplexers. The low ON resistance of the QS3251 allowsinputs to be connected to outputs without adding propagation delay andwithout generating additional ground bounce noise.Mux/Demux devices provide an order of magnitude faster speed thanequivalent logic devices.The QS3251 is characterized for operation at -40°C to +85°C.

QS3251S1G APPLICATIONS:

• Logic replacement • Video, audio, graphics switching, muxing • Hot-swapping, hot-docking • Voltage translation (5V to 3.3V)
