FST3126

FST3126 4-Bit Bus Switch The ON Semiconductor FST3126 is a quad, high performance switch. The device is CMOS TTL compatible when operating between 4 and 5.5 Volts. The device exhibits extremely low RON and adds nearly zero propagation delay. The device adds no noise or ground bounce to the system. The device consists of four independent 1−bit switches with separate Output/Enable (OE) pins. Port A is connected to Port B when OE is high. If OE is low, the switch is high Z. Features RON t 4 W Typical Less Than 0.25 ns−Max Delay Through Switch Nearly Zero Standby Current No Circuit Bounce Control Inputs are TTL/CMOS Compatible Pin−For−Pin Compatible With QS3126, FST3126, CBT3126 All Popular Packages: SOIC−14 & TSSOP−14 These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant OE1 1A 1B OE2 2A 2B GND 1 2 3 4 5 6 7 14 VCC 13 OE4 12 4A 11 4B 10 OE3 9 3A 8 3B Figure 1.
