CBT1621020-bit bus switch with 10-bit output enables

FEA TURES

•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 or as one 20-bit bus switch. When OE bus switch is on, and port A is connected to port B. When OE

) inputs. It can be used as two 10-bit bus switches

is low, the associated 10-bit

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.
