PulseCount 1.1 board

Does anyboady know what IC’s are use for the level shifting on the pulse inputs of the Pulsecount 1.1 board ? IC type is not mentionned in the schematics on the website. (two small 6-pin IC’s).
Would those be capable of shifting from 0/24V levels ?


@ StefaanV - The part number for the logic ICs is 74LVC1G57GW,125.

OK Aron, thanks for the input.
