The PTA977P (or 977W) and PT8A978P (or 978LW) provide a complete control functions to the remotecontrolled toy. The PT8A977P/977W has five input pins corresponding with the five function buttons i.e, forward, backward, rightward, leftward and turbo. The encoding circuit in the PT8A977P/977W sends digital codes to the two output pins SO and SC. The digital co.
• PT8A977P/977W works as encoder and PT8A978P/978LW works as decoder
• Five pins for five control functions
• Operating power-supply voltage: 2.5V to 5.0V (977P, 977W, 978P), 2.0V to 5.0V (978LW)
• Auto-power-off if no press on any button in 8s or continuously press on any button over 4 minues
• Press on any button as wake up (977P, 977W)
• Manual-power-off with OFF button
• One output pin used for external power control (977P, 977W)
• On-chip oscillator with an external resistor
• On-chip reversing amplifiers (978P, 978LW)
• Low operating current
• Few external components needed
• Package: 14.
