The FST3244 is an octal bus switch with high-speed CMOS TTL compatibility and low on resistance. It allows connections between inputs and outputs without adding propagation delay or generating additional ground bounce noise.
The document describes the Fairchild FST3244, an octal bus switch designed to provide 8-bits of high-speed CMOS TTL-compatible bus switching. The device is organized as two 4-bit switches with separate Gate Enable (GE) inputs and features low on-resistance to minimize propagation delay and ground bounce noise.
| Free Air Operating Temperature | -40 °C to +85 °C |
|---|---|
| Control Pin Input Capacitance | Typ 3 pF |
The device uses a standard '244 pin-out.
It is organized as two 4-bit switches with separate GE inputs.
When OE is LOW, the switch is ON and Port A is connected to Port B.
