LSF0204: If can be used for 1.8V LVCMOS level shifter

Gary Jiang

Part Number: LSF0204

Hi team,

My customer used to use LSF0204, but now they need 1.8V LVCMOS level shifter. I checked datasheet, the VIL and VIH of port A can meet the LVCMOS specification, but I find no spec on VOL and VOH. Can LSF0204 be used for 1.8V LVCMOS?

Thanks!

The LSF is a passive switch; The V_OL of the LSF is the V_OL of the driving device plus the voltage drop over the switch.

The actual voltage depends on the drive strength of the other device and on the current (i.e., the size of the pull-up resistors).

Depending on the application, other level shifters are easier to use.
