INTEGRATED CIRCUITS CBTD16210 20-bit level shifting bus switch with 10-bit output enables Product specification 2000 Oct 12 Supersedes data of 2000 Sep 25 Philips Semiconductors Product specification 20-bit level shifting bus switch CBTD16210 with 10-bit output enables FEATURES DESCRIPTION The CBTD16210 provides 20 bits of high-speed TTL-compatible bus 5 switch connection between two ports switching. The low on-state resistance of the switch allows TTL compatible control input levels connections to be made with minimal propagation delay. Designed to be used in 5.5 V to 3.3 V level shifting applications A diode to V is integrated in the circuit to allow for level shifting CC between 5 V inputs and 3.3 V outputs. Package options include shrink small outline (SSOP) and thin The device is organized as a dual 10-bit bus switch with separate shrink small outline (TSSOP) output-enable (OE) inputs. It can be used as two 10-bit bus switches or as one 20-bit bus switch. When OE is low, the associated 10-bit bus switch is on, and port A is connected to port B. When OE is high, the switch is open, and a high-impedance state exists between the ports. The CBTD16210 is characterized for operation from 40C to +85C.
