SN74CBTD3305CDR Description

Short technical summary and product information.

The SN74CBTD3305CDR from Texas Instruments is a dual FET bus switch featuring level shifting capabilities and undershoot protection. It operates with a VCC range of 4.5 V to 5.5 V and supports data I/Os from 0 V to 5 V signaling levels. This device offers low ON-state resistance of typically 3 Ω and low input/output capacitance of 5 pF, minimizing signal distortion.

 

Key features include undershoot protection for off-isolation on A and B ports up to -2 V, and an integrated diode to VCC for 5-V input to 3.3-V output level shifting. The SN74CBTD3305CDR is organized as two independent 1-bit bus switches, each controlled by separate output-enable inputs. It can function as two individual switches or one 2-bit switch, supporting bidirectional data flow with near-zero propagation delay.

 

This bus switch is suitable for digital and analog applications such as USB interfaces, memory interleaving, bus isolation, and low-distortion signal gating. It is supplied in an 8-SOIC package suitable for surface mounting and operates within a temperature range of -40°C to 85°C.
