Configurable 4-Bit To 40-Bit Bus Switch With -2V Undershoot Protection And Selectable Level Shifting

The Fairchild Universal Bus Switch FSTUD32450 provides 4-bit, 5-bit, 8-bit, 10-bit, 16-bit, 20-bit...40-bit of high-speed CMOS TTL-compatible bus switching. The low On Resis- tance of the Switch allows inputs to be connected to out- puts without adding propagation delay or generating additional ground bounce noise. The FSTUD32450 is designed to allow customer configu- ration control of the enable connections. The device CAN be organized as either a ten 4-bit, eight 5-bit, four 10-bit, two 20-bit or one 40-bit enabled bus Switch Also achievable 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.
