5L4433A Dual/Quad 4x8 Reed Matrix

L4433A Simplified Schematic for One-Wire Mode

		Matrix 1
1C1	1C2	1C8
1C1 bypass	1C2 bypass	1C8 bypass

NOTE: Although rows are numbered the same across the matrices, they are electrically separate from one another.

NOTE:

Matrix Relays: Reed non-latching

Analog Bus Relays: Armature non-latching

NOTE: All series resistors shown are 100Ω.
