CBT16210
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.

NOTES: 1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C. 3. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
