Configurable 4-Bit To 20-Bit Bus Switch With Selectable Level Shifting

The Fairchild Universal Bus Switch FSTD16450 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 FSTD16450 is designed to allow customer configura- tion control of the enable connections. The device is orga- nized as either a 4-bit, 5-bit, 10-bit or 20-bit bus Switch 8- bit and 16-bit configurations are also achievable (see Func- tional Description). The device's bit configuration is chosen 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. Another key device feature is the addition of a level shifting select pin, S2. When S2 is LOW, the device behaves as a standard N-MOS Switch When S2 is HIGH, a Diode to VCC is integrated into the circuit allowing for level shifting between 5V inputs and 3.3V outputs By Fairchild Semiconductor
