Overview
PT8A977B/978B/978BL 5-Function Remote Controller Features Description • PT8A977B works as encoder and PT8A978B/ 978BL works as decoder • Five pins for five control functions • Operating power-supply voltage: 2.
5V to 5.
0V (978B), 2.
0V to 5.
0V (978BL), 1.
8V to 5.
0V(977B) • Auto-power-off and oscillation-off if no press on any button (977B) • Press on any button to wake up (977B) • One output pin used for external power control (977B) • On-chip oscillator with an external resistor • On-chip reversing amplifiers (978B, 978BL) • Low operating current • Few external components needed • Package: 14-pin DIP, 14-pin SOIC, 16-pin DIP , 16-pin SOIC, die form and wafer form The PT8A977B and PT8A978B (or 978BL) provide complete control functions to the remote-controlled toy.
The PT8A977B has five input pins corresponding with the five function buttons i.
e, forward, backward, rightward, leftward and turbo.
The encoding circuit in the PT8A977B sends digital codes to the two output pins SO and SC.
