SP3232ECN-L Pinout

Package: SOIC-16

Notes

• SP3232ECN-L is a 16-pin SOIC variant (SP3232E family).
• The SP3232E variant does not include EN (Receiver Enable) or SHDN (Shutdown Control) pins present in SP3222E variants.
• All pin numbers extracted from the SP3232E column of the source pin-function table.
• Pin names and descriptions match the datasheet exactly as listed.

Unless otherwise noted, the following specifications apply for V CC = 3.0V to 5.5V with T AMB = T MIN to T MAX , typical values apply at V CC = 3.3V or 5.0V and T AMB = 25°C.
