2002 Dec 13
FEATURES
• 5 Ω switch connection between two ports
• TTL compatible control input and output levels
• Undershoot protection included to prevent shoot through level
changes
• Latch-up protection exceeds 500 mA per JESD78
• ESD protection exceeds 2000 V HBM per JESD22-A114,
200 V MM per JESD22-A115 and 1000 V CDM per JESD22-C101
DESCRIPTION
The CBTS3384 provides ten 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.
The CBTS3384 device is organized as two 5-bit bus switches with
separate output-enable (OE
) inputs. When OE is LOW, the switch is
on and port A is connected to B. When OE
is HIGH, the switch is
open and high-impedance state exists between the two ports.
The CBTS3384 is characterized for operation from -40 to +85 °C.
