The PT8A977B and PT8A9781 provide a complete control functions to the remote-controlled toy. The PT8A9781 has four output pins corresponding with the four actions i.e, forward, backward, right, left. The received signals are amplified by the three-stage amplifier, and then the appropriate amplified signals are sampled, fault-tolerantly checked and decoded to.
• PT8A977B works as encoder and PT8A9781 works as decoder
• Four control functions
• Operating power-supply voltage: 1.8V to 5.0V(977B) 1.0V to 1.5V (9781)
• Auto-power-off and oscillation-off if no press on any button (977B)
• Press on any button to wake up (977B)
• On-chip oscillator with an external resistor (977B)
• On-chip oscillator with an external resistor and capacitor (9781)
• On-chip amplifiers (9781)
• Low operating current
• Few external components needed
