General Description

The 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.

Features

■ 4Ω 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
