The encoding circuit in the PT8A977B • Auto-power-off and oscillation-off if no press on sends digital codes to the two output pins SO and SC. any button (977B) The digital codes correspond to the definite function • Press on any button to wake up (977B) buttons or their combinations. The SO and SC outputs • One output pin used for external power control are used in wireless and infra-red applications (977B) respectively. • On-chip oscillator with an external resistor • On-chip reversing amplifiers (978B, 978BL) The PT8A978B (or 978BL) has five output pins • Low operating current corresponding with the five actions. The received signals • Few external components needed are amplified by the three-stage amplifier, and then the • Package: 14-pin DIP, 14-pin SOIC, appropriate amplified signals are sampled, fault-tolerantly 16-pin DIP checked and decoded to control the actions of the remote- , 16-pin SOIC, die form and wafer form controlled toy. Ordering Information There is an internal oscillator in the PT8A977B and 978B/ P a r t N o.

By adding an external resistor conveniently, the oscillator will be constructed. The oscillator frequency can be adjusted by the external resistor. The relative error between the frequencies of the two on-chip oscillators in the PT8A977B and PT8A978B/978BL must be less than ±25%. The auto-power-off function is achieved by an internal counter (977B). The PC output is used to control on/off state of the external power supply. Press on any function button will wake up the chip promptly.
