NXP Semiconductors CBT3245
The CBT3245 provides eight bits of high-speed TTL-compatible bus switching in a standard ’245 device pinout. The low on-state resistance of the switch allows connections to be made with minimal propagation delay. The CBT3245 device is organized as one 8-bit switch.FEATURES
● Functionally equivalent to QS3245● Standard ’245-type pinout
● 5Ω switch connection between two ports
● TTL compatible control input levels
● Package options include plastic small outline (D), shrink small outline (DB), thin shrink small outline (TSSOP)
DESCRIPTION
When enable (OE) is low, the 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 two ports. The CBT3245 is characterized for operation from –40°C to 85°C.
