Important notice Dear Customer, On 7 February 2017 the former NXP Standard Product business became a new company with the tradename Nexperia. Nexperia is an industry leading supplier of Discrete, Logic and PowerMOS semiconductors with its focus on the automotive, industrial, computing, consumer and wearable application markets In data sheets and application notes which still contain NXP or Philips Semiconductors references, use the references to Nexperia, as shown below. Instead of CBT3245A Octal bus switch Rev. 3 5 January 2012 Product data sheet 1. General description The CBT3245A provides eight bits of high-speed TTL-compatible bus switching. The low ON resistance of the switch allows connections to be made with minimal propagation delay. The CBT3245A is organized as one 8-bit bus switches with one output enable (OE) input. When OE is LOW, the switch is on and port A is connected to the B port. When OE is HIGH, each switch is disabled. The CBT3245A is characterized for operation from 40 C to +85 C. 2. Features and benefits 5 switch connection between two ports TTL-compatible control input levels Multiple package options Latch-up protection exceeds 500 mA per JESD78 ESD protection: HBM JESD22-A114F exceeds 2000 V MM JESD22-A115B exceeds 150 V CDM JESD22-C101C exceeds 1000 V 3.
