74FST3126

74FST3126 4-Bit Bus Switch The ON Semiconductor 74FST3126 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. http://onsemi.com MARKING DIAGRAMS 14 1 SO–14 D SUFFIX CASE 751A 14 FST3126 AWLYWW 1 14 14 1 FST 3126 ALYW 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: QSOP–16, TSSOP–14, SOIC–14 OE1 1A 1B OE2 2A 2B GND 1 2 3 4 5 6 7 14 13 12 11 10 9 8 VCC OE4 4A 4B OE3 3A 3B TSSOP–14 DT SUFFIX CASE 948G 1 16 1 16 S3126 ALYW Figure 1.
