CBTD3861 10-bit level shifting bus switch with output enable Rev. 3 6 March 2019 Product data sheet 1. General description The CBTD3861 provides ten 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 CBTD3861 device is organized as one 10-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 CBTD3861 is characterized for operation from -40 C to +85 C. 2. Features and benefits Designed to be used in 5 V to 3.3 V level shifting applications with internal diode 5 switch connection between two ports TTL-compatible control input levels Latch-up protection exceeds 100 mA per JESD78 ESD protection: HBM JESD22-A114F exceeds 2000 V CDM JESD22-C101C exceeds 1000 V 3.
