PT8A977B/978B/978BL

5-Function Remote Controller

Features

• 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

Description

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.

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.

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%.

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.

Note:

Adding E= Pb-free or Pb-free and Green

Adding X suffix=Tape/Reel
