ADG3242BRJ-R2

Signal Switches, Multiplexers, Decoders Overview

The ADG3242BRJ-R2 is a 2-bit common control level translator bus switch designed for 2.5 V or 3.3 V supply operation. It features a propagation delay of 225 ps and an on-resistance of 4.5 Ω, supporting data rates up to 1.5 Gbps. The device operates within a supply voltage range of 2.3 V to 3.6 V and includes a selectable level translation function via the SEL pin. It provides bidirectional signal switching with low power dissipation and minimal ground bounce noise in an 8-lead SOT-23 package.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides bidirectional switching with extremely low propagation delay and high switching speed.
• Enables selectable voltage level translation between 3.3 V, 2.5 V, and 1.8 V domains using the SEL control pin.
• Offers low on-resistance and small signal bandwidth suitable for high-speed digital interfaces.
• Maintains high impedance state during power-up and power-down sequences to protect connected circuitry.

Signal Switches, Multiplexers, Decoders Applications

• Voltage translation between 3.3 V and 2.5 V systems
• Voltage translation between 3.3 V and 1.8 V systems
• Voltage translation between 2.5 V and 1.8 V systems

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify that the specific ordering suffix matches the required packaging format, as the BRJ-R2 designation indicates a reel configuration distinct from other variants like REEL7. Confirm the temperature range and lead-free status against the official Analog Devices ordering guide to ensure compliance with project specifications before finalizing procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when interfacing mixed-voltage logic families requiring bidirectional data transfer with minimal timing skew. The integrated level translation capability eliminates the need for external clamping diodes or separate translators. Ensure the application voltage does not exceed the maximum pass voltage limits defined in the specifications for the chosen supply configuration.

Signal Switches, Multiplexers, Decoders Part Context

This device belongs to the ADG3242 series of bus switches manufactured by Analog Devices. It is part of a family of low-voltage CMOS switches designed for high-speed data routing and voltage domain interfacing. The RJ-8 package variant offers a compact footprint suitable for space-constrained printed circuit board layouts.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Direct substitutes include ADG3242BRJ-REEL and ADG3242BRJZ-REEL7, which share identical electrical characteristics and pinouts but differ in packaging quantities or lead-free certification.
