PT8A978BL Overview
PT8A977B works as encoder and PT8A978B/ 978BL works as decoder Five pins for five control functions Operating power-supply voltage: 14-pin DIP, 14-pin SOIC, 16-pin DIP , 16-pin SOIC, die form and wafer form The PT8A977B and PT8A978B (or 978BL) provide plete control functions to the remote-controlled toy. The PT8A977B has five input pins corresponding with the five function buttons i.e, forward, backward, rightward,...
