1. General description

The CBT3384 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 CBT3384 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 CBT3384 is characterized for operation from −40 °C to +85 °C.

2. Features

n 5 Ω switch connection between two ports

n TTL-compatible control input levels

n Multiple package options

n See CBTD3384 for CBT3384 with level shifting diodes

n Latch-up protection exceeds 100 mA per JESD78

n ESD protection:

u HBM JESD22-A114E exceeds 2000 V

u CDM JESD22-C101C exceeds 1000 V
