1 / 6 page © 2005 Fairchild Semiconductor Corporation DS500421 www.fairchildsemi.com May 2001 Revised June 2005 FSTD16861 20-Bit Bus Switch with Level Shifting General Description The Fairchild Switch FSTD16861 provides 20-bits of high- speed CMOS TTL-compatible bus switching. The low On Resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. A diode to VCC has been integrated into the circuit to allow for level shifting between 5V inputs and 3.3V outputs. The device is organized as a 10-bit or 20-bit bus switch. When OE1 is LOW, the switch is ON and Port 1A is con- nected to Port 1B. When OE2 is LOW, Port 2A is connected to Port 2B. When OEX is HIGH, a high impedance state exists between the A and B Ports. Features s 4 : switch connection between two ports. s Minimal propagation delay through the switch. s Low lCC. s Zero bounce in flow-through mode. s Control inputs compatible with TTL level. s TruTranslation ¥ voltage translation from 5.0V inputs to 3.3V outputs s Power-off high impedance inputs and outputs s Supports live insertion/withdrawal (Note 1) Note 1: To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver. Ordering Code: Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code. TruTranslation ¥ is trademark of Fairchild Semiconductor Corporation.
