Product data

CBT3384

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.
