ISL8323IB

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL8323IB is a dual RS-232 transceiver manufactured by Intersil, designed for low-power applications. It operates within a supply voltage range of 3V to 5.5V and supports data rates up to 120kbps. The device integrates charge pumps that require only two external 0.1µF capacitors, eliminating the need for inductors or transformers. It features ±7.5kV ESD protection on all pins and meets TIA/EIA-232-F standards. Packaged in a 16-pin SOIC, it functions over an industrial temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the manufacturer source carefully, as Intersil was acquired by Renesas Electronics. Confirm the specific suffix 'IB' corresponds to the standard SOIC package and industrial temperature grade. Request official datasheets to validate pinout compatibility and electrical characteristics against current design requirements before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing space-constrained portable devices requiring RS-232 communication. Ensure the system power budget accommodates the 3V to 5.5V operating range. Verify that the 120kbps maximum data rate satisfies the application's throughput needs. Check for alternative packages if surface area constraints differ from the SOIC-16 footprint.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ISL83xx family of RS-232 transceivers, which are characterized by low power consumption and single-supply operation. The family includes variants with different driver/receiver counts and ESD ratings. The ISL8323 specifically provides two drivers and two receivers, balancing performance and pin count for general-purpose serial communication interfaces.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Consider the MAX3232 or TRS3232 as functional equivalents. Verify pin-to-pin compatibility and ensure the replacement supports the required 3V to 5.5V supply range and ESD protection levels.
