CBTD3384

INTEGRATED CIRCUITS CBTD3384 10-bit level shifting bus switch with 5-bit output enables Product data Supersedes data of 2000 Aug 30 File under Integrated Circuits — ICL03 2001 Dec 20 Philips Semiconductors Philips Semiconductors 10-bit level shifting bus switch with 5-bit output enables Product data CBTD3384 FEATURES 5 Ω switch connection between two ports TTL compatible control input and output levels Designed to be used in 5 V to 3.3 V level shifting applications Latch-up protection exceeds 500 mA per JESD78 ESD protection exceeds 2000 V HBM per JESD22-A114, and 1000 V CDM per JESD22-C101 DESCRIPTION The CBTD3384 provides ten bits of high-speed TTL-compatible level shifting bus switching. The low on-state resistance of the switch allows connections to be made with minimal propagation delay. The gate voltage of the enabled switch is lowered by a diode to allow convenient level shifting between 5 V and 3.3 V levels on either side of the CBTD3384. The CBTD3384 device is organized as two 5-bit bus switches with separate output-enable (OE) inputs. When OE is low, the switch is on and port A is connected to B. When OE is high, the switch is open and high-impedance state exists between the two ports. The CBTD3384 is characterized for operation from –40 to +85 °C.
