This document describes the features and characteristics of the SCDS133A product, including undershoot protection for the A and B ports, integrated diode for 5V to 3.3V level shift, bidirectional data flow, and low ON-state resistance.
The SN74CBTD3384C is a high‑speed TTL‑compatible FET bus switch that can be used as two independent 5‑bit switches or combined as a single 10‑bit switch. It features integrated level‑shifting diodes, bidirectional data flow, low ON‑state resistance, and partial‑power‑down capability.
The device operates from a 4.5 V to 5.5 V supply, supports input voltages down to –2 V on the A and B ports, and provides ESD protection up to 2000 V HBM. Detailed electrical characteristics, mechanical dimensions, and ordering information are included.
