Features
Description
• PT8A977B works as encoder and PT8A978B/
978BL works as decoder
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.
The digital codes correspond to the definite function
buttons or their combinations. The SO and SC outputs
are used in wireless and infra-red applications
respectively.
• 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
The PT8A978B (or 978BL) has five output pins
corresponding with the five actions. The received signals
are amplified by the three-stage amplifier, and then the
appropriate amplified signals are sampled, fault-tolerantly
checked and decoded to control the actions of the remote-
controlled toy.
• Few external components needed
• Package: 14-pin DIP, 14-pin SOIC, 16-pin DIP
, 16-pin SOIC, die form and wafer form
There is an internal oscillator in the PT8A977B and 978B/
978BL respectively. 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%.

Die Form
Wafer Form
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.
