供应高速多路复用器 IDTQS3253QG8
信息内容：品牌:IDT 型号:IDTQS3253QG8IDTQS3253QG8FEATURES:• Enhanced N channel FET with no inherent diode to Vcc• 5Ω bidirectional switches connect inputs to outputs• Pin compatible with the 74F253, 74FCT253, and 74FCT253T• Zero propagation delay, zero ground bounce• Undershoot clamp diodes on all switch and control inputs• TTL-compatible control inputs• Available in QSOP and S1 packagesDESCRIPTION:The QS3253 is a high-speed CMOS TTL-compatible dual 4:1 multiplexer/demultiplexer with 3-state outputs. The QS3253 is function andpinout compatible version of the 74F253, 74FCT253, and the 74ALS/AS/LS253 dual 4:1 multiplexers. The low ON resistance of the QS3253 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 QS3253 is characterized for operation at -40°C to +85°C.
