1. General description
The CBTD3384 provides ten 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 CBTD3384 device is organized as two 5-bit bus switches with two separate output
enable (1OE
, 2OE) inputs. When nOE is LOW, the switch is on and port A is connected to
the B port. When nOE
is HIGH, each switch is disabled.
The CBTD3384 is characterized for operation from 40 C to +85 C.
2. Features and benefits
