2
2001 Dec 20 853-2187 27501

FEATURES

•5 Ω switch connection between two ports
•TTL compatible control input and output levels
•See CBTS3384 for CBT3384 with Schottky diode undershoot
protection
•See CBTD3384 for CBT3384 with level shifting diodes
•Latch-up is done to JESDEC Standard JESD78 which exceeds
100 mA
•ESD classification testing is done to JESDEC Standard JESD22.
Protection exceeds 2000 V to HBM per method A114 and
1000 V CDM per method C101.

DESCRIPTION

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