FEATURES
•5Ω switch connection between two ports
•TTL compatible control input levels
•Designed to be used in level shifting applications
•Package options include shrink small outline (SSOP) and thin shrink small outline (TSSOP)
•ESD protection exceeds 1000 V CDM per JESD22-C101
•Latch-up testing is done to JESDEC Standard JESD78 which exceeds 100 mA
DESCRIPTION
The CBTD16211 provides 24 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.
A diode to VCC is integrated in the circuit to allow for level shifting between 5 V inputs and 3.3 V outputs.
The device is organized as a dual 12-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 CBTD16211 is characterized for operation from ±40 to +85 °C.
