CBTD3384 10-bit level shifting bus switch with 5-bit output enables Rev. 10 12 March 2021 Product data sheet 1. General description The CBTD3384 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 CBTD3384 device is organized as two 5-bit bus switches with two separate output enable (1OE, 2OE) inputs. When nOE is LOW, the switch is on and port A is connected to the B port. When nOE is HIGH, each switch is disabled. 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-A114E exceeds 2000 V CDM JESD22-C101C exceeds 1000 V Specified from -40 C to +85 C 3.
