FSTD3125: 4-Bit Bus Switch with Level Shifting
Fairchild switch FSTD3125 provides four high-speed CMOS TTL-compatible bus switches. 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 four one-bit switches with separate /OE inputs. When /OE is LOW, the switch is ON and port A is connected to port B. When /OE is HIGH, the switch is OPEN and a high-impedance state exists between the two ports.
Features
- 4ohm switch connection between two ports
- Minimal propagation delay through the switch
- Low lCC
- Zero bounce in flow-through mode
- Control inputs compatible with TTL level
- TruTranslation™ voltage translation from 5.0V inputs to 3.3V outputs
