This datasheet introduces the features and characteristics of FST3245 Octal Bus Switch
The Fairchild FST3245 is an 8-bit high-speed CMOS TTL-compatible bus switch designed to connect inputs to outputs with minimal propagation delay and zero bounce in flow-through mode. The device features a standard '245 pin-out and is organized as an 8-bit switch where the Output Enable (OE) input controls the connection between Port A and Port B.
| Organization | 8-bit switch |
|---|---|
| Operating Temperature | -40°C to +85°C |
| Switch On Resistance | 7.2 Ohms (max) |
When OE is LOW, the switch is ON and Port A is connected to Port B. When OE is HIGH, the switch is OPEN.
Yes, the control inputs are compatible with TTL level.
