The FST3245 8-Bit Bus Switch is a high-speed CMOS TTL-compatible bus switch that features 4Ω switch connection between two ports, minimal propagation delay, and low ICC. It also has zero bounce in flow-through mode and control inputs compatible with TTL level.
The Fairchild FST3245 is an 8-bit high-speed CMOS bus switch designed for TTL compatibility. It features a standard '245 pin-out and allows four switch connections between two ports. The device operates by connecting Port A to Port B when the /OE input is LOW, and entering a high-impedance state when /OE is HIGH.

When /OE is LOW, the switch connects Port A to Port B. When /OE is HIGH, the switch is OPEN and a high-impedance state exists.
Yes, the device features control inputs compatible with TTL level and is described as CMOS TTL-compatible.
The absolute maximum rating for the supply voltage is 7.0 V.
