CBT3245A is a 8-bit high-speed TTL-compatible bus switch produced by Philips
The Philips CBT3245A is an octal bus switch designed for high-speed TTL-compatible bus switching. The device organizes eight bits into a single switch, connecting Port A to Port B when the Output Enable (OE) input is LOW. When OE is HIGH, the switch enters a high-impedance state. It is characterized for operation from -40 to +85 °C and features latch-up and ESD protection.
