Product details

Bus switch for signal isolation – 5 channels, 1:1 topology

The SN74CB3T3384DW is a 5-circuit, 1:1 bus switch from TI's 74CB series, designed to connect or isolate digital signal paths with minimal propagation delay. Two independent circuits each contain five switches, giving you ten total switching elements in a single 24-SOIC package. Supply voltage range of 2.3V to 3.6V means this part lives on a 3.3V or 2.5V rail — it is not a 5V-tolerant bus switch. If your upstream logic swings 5V, you need a level-shifting buffer ahead of this device.

The 24-SOIC wide-body package (7.50 mm body width) gives better thermal coupling to the PCB than the narrow SOIC variant.

Frequently asked questions

Is SN74CB3T3384DW RoHS compliant?

Yes, it is ROHS3 compliant per TI's lifecycle record.

What is the difference between SN74CB3T3384DW and SN74CB3T3384PW?

The DW suffix indicates a 24-SOIC wide-body package (7.50 mm width); the PW suffix is a 24-TSSOP (4.40 mm width). Electrical specifications are identical — the choice is footprint and board-space driven.

Is SN74CB3T3384DW compatible with 5V logic?

No. The supply voltage range is 2.3V to 3.6V. 5V logic levels on the signal pins exceed the recommended operating conditions. Use a level translator if 5V signals must be switched.
