Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore (_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild_questions@onsemi.com.

The low on resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. ■ 4Ω switch connection between two ports. The device can be used in applications where two buses need to be addressed simultaneously. The FST16233 can be used as two 8-bit to 16-bit multiplexers or as one 16-bit to 32-bit multiplexer. ■ Control inputs compatible with TTL level. ■ Minimal propagation delay through the switch. ■ Low lCC. ■ Zero bounce in flow-through mode. Two select (S1, S0) and two test (TEST0, TEST1) inputs provide switch enable and multiplexer select control. The FST16233 is designed to prevent through-current when switching buses.
