FEATURES
•5Ω switch connection between two ports
•TTL compatible control input levels
•Package options include shrink small outline (SSOP) and thin shrink small outline (TSSOP)
•ESD exceeds: CDM 1000 V; HBM 2000 V
DESCRIPTION
The CBT16210 provides 20 bits of high-speed TTL-compatible bus switching. The low on-state resistance of the switch allows connections to be made with minimal propagation delay.
The device is organized as a dual 10-bit bus switch with separate 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 CBT16210 is characterized for operation from ±40°C to +85°C.
