DESCRIPTION
The DG408L/409L are low voltage pin-for-pin compatible
companion devices to the industry standard DG408/409 with
improved performance.
designed to connect one of eight inputs to a common output as
determined by a 3-bit binary address (A0, A1, A2). The DG409L
is a dual 4-channel differential analog multiplexer designed to
connect one of four differential inputs to a common dual output
as determined by its 2-bit binary address (A0, A1).
Break-before-make switching action to protect against
momentary crosstalk between adjacent channels.
Using BiCMOS wafer fabrication technology allows the
DG408L/409L to operate on single and dual supplies. Single
supply voltage ranges from 3- to 12-V while dual supply
operation is recommended with "3 to "6 V.
The DG408L/409L provides lower on-resistance, faster
switching time, lower leakage, less power consumption and
higher off-Isolation than the DG408/409.
The DG408L is an 8-channel single-ended analog multiplexer

Notes
a. Leakage parameters are guaranteed by worst case test condition and not subject to production test.
b. Room = 25_C, Full = as determined by the operating temperature suffix.
c. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
d. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.
e. Guaranteed by design, not subject to production test.
