WebLike, TTL 74LHS Series, has a range from 0 to 0.8V for logic “LOW” and from 2.8 to 5.0V for logic “HIGH”. The pull-up or down resistance value depends on the logic state of the input. At logic “LOW”, the input becomes a source (positive current) and a sink (negative current), otherwise (logic “HIGH). WebModel Number 16 channel Relay module. Condition New. Type Voltage Regulator.
