1 / 10 page Preliminary © 2001 Fairchild Semiconductor Corporation DS500423 www.fairchildsemi.com February 2001 Revised August 2001 FSTU162450 Configurable 4-Bit to 20-Bit Bus Switch with −2V Undershoot Protection and 25 Ω Series Resistors in Outputs (Preliminary) General Description The Fairchild Universal Bus Switch FSTU162450 provides 4-bit, 5-bit, 8-bit, 10-bit, 16-bit, 20-bit 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. The FSTU162450 is designed to allow “customer” configu- ration control of the enable connections. The device can be organized as either a five 4-bit, four 5-bit, two 10-bit or one 20-bit enable bus switch. Also achieveable are 8-bit and 16-bit enabled configurations (see Functional Description). The device’s bit configuration is controlled through select pin logic. (see Truth Table). When OEx is LOW, Port Ax is connected to Port Bx. When OEx is HIGH, the switch is OPEN. The A and B Ports are protected against undershoot to support an extended range to 2.0V below ground. Fairchild’s integrated Undershoot Hardened Circuit ( UHC ) senses undershoot at the I/O and responds by preventing voltage differentials from developing and turn- ing the switch on. Features s Undershoot protected to −2V (A and B Ports) s 25 Ω 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 See Applications Notes AN-5008 and AN-5021 for UHC details s Also packaged in plastic Fine-Pitch Ball Grid Array (FBGA) (Preliminary) Applications Note Select pins S0, S1, S2 are intended to be used as static user configurable control pins. The AC performance of these pins has not been characterized or tested. Switching of these select pins during system operation may tempo- rarily disrupt output logic states and/or enable pin controls. Ordering Code: Note 1: BGA package available in Tape and Reel only. Note 2: Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code. UHC is a trademark of Fairchild Semiconductor Corporation.
