1. General description
The CBT3245A provides eight bits of high-speed TTL-compatible bus switching. The low
ON resistance of the switch allows connections to be made with minimal propagation
delay.
The CBT3245A is organized as one 8-bit bus switches with one outp ut enable (OE) input.
When OE is LOW, the switch is on and port A is connected to the B port. When OE is
HIGH, each switch is disabled. The CBT3245A is characterized for operation from 40 C
to +85 C.
2. Features and benefits
5 switch connection between two ports
TTL-compatible control input levels
Multiple package options
Latch-up protection exceeds 500 mA per JESD78
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115B exceeds 150 V
CDM JESD22-C101C exceeds 1000 V
