CBTD3384PW-Q100J

Signal Switches, Multiplexers, Decoders Overview

The CBTD3384PW-Q100J is a dual 5-pole, single-throw bus switch designed for 5 V to 3.3 V level shifting applications. It features two output enable inputs (nOE) that each control five switch channels, with switches disabled when the associated nOE input is HIGH. The device includes IOFF circuitry for partial power-down mode operation and latch-up protection exceeding 100 mA per JESD78. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). It operates within a supply voltage range of 4.5 V to 5.5 V and an ambient temperature range of -40 °C to +85 °C.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific package variant TSSOP24 (SOT355-1) matches your PCB footprint requirements. Confirm the AEC-Q100 Grade 3 qualification aligns with your automotive design specifications. Ensure all unused control inputs are held at VCC or GND to ensure proper device operation during procurement and integration phases.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when designing circuits requiring bidirectional data transfer between 5 V and 3.3 V logic domains. The dual 5-pole configuration allows independent control of two 5-bit buses via separate nOE inputs. Consider the low on-resistance and fast propagation delay for high-speed signal integrity in automotive environments.
