FSTD16861 20-Bit Bus Switch with Level Shifting May 2001 Revised April 2004 FSTD16861 20-Bit Bus Switch with Level Shifting General Description Features The Fairchild Switch FSTD16861 provides 20-bits of high-4Ω switch connection between two ports. speed CMOS TTL-compatible bus switching. The low OnMinimal propagation delay through the switch. Resistance of the switch allows inputs to be connected to Low l .

When OE is HIGH, a high impedance state X Note 1: To ensure the high-impedance state during power up or power down, OE should be tied to V through a pull-up resistor; the minimum exists between the A and B Ports. CC value of the resistor is determined by the current-sourcing capability of the driver.
