ADG3245BCP

Signal Switches, Multiplexers, Decoders Overview

The ADG3245BCP is an 8-bit, 2-port digital bus switch and level translator operating from a 2.3 V to 3.6 V supply. It features a propagation delay of 225 ps and supports data rates up to 1.244 Gbps with a small signal bandwidth of 610 MHz. The device provides selectable voltage translation between 3.3 V, 2.5 V, and 1.8 V logic levels via the SEL pin. It is housed in a 20-lead LFCSP package (CP-20-6) suitable for surface mount applications.

Signal Switches, Multiplexers, Decoders Feature Summary

• Bidirectional switching with extremely low propagation delay
• Selectable voltage translation between 3.3 V, 2.5 V, and 1.8 V supplies
• High-speed operation supporting data rates up to 1.244 Gbps
• Low on-resistance with minimal ground bounce noise generation

Signal Switches, Multiplexers, Decoders Applications

• Voltage translation between 3.3 V and 1.8 V systems
• Voltage translation between 3.3 V and 2.5 V systems
• Voltage translation between 2.5 V and 1.8 V systems
• Bus isolation and hot swap/hot plug protection

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific package variant when ordering, as the ADG3245BCPZ denotes the LFCSP option while BRU variants indicate TSSOP. Confirm RoHS compliance status and ensure the selected temperature range matches the industrial specification (-40°C to +85°C). Cross-reference the exact suffix with manufacturer documentation to avoid confusion between reel and tube packaging options.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component for mixed-voltage interfaces requiring minimal signal distortion and high speed. The integrated level translation eliminates external components for 3.3 V to 1.8 V conversions. Ensure the load capacitance and drive requirements align with the specified on-resistance characteristics. Consider the LFCSP package for space-constrained designs due to its smaller footprint compared to TSSOP.

Signal Switches, Multiplexers, Decoders Part Context

The ADG3245 belongs to Analog Devices' family of low-voltage CMOS bus switches. It is designed to interface digital signals between different voltage domains without introducing significant timing skew or noise. The device serves as a bridge for microprocessors, ADCs, and DSPs operating at varying supply voltages within the same system architecture.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Direct substitutes include ADG3245BRU and ADG3245BRUZ, which share identical electrical specifications but utilize the 20-lead TSSOP package instead of the LFCSP form factor.
