Features
Introduction
The PT8A976, PT8A976A and PT8A976B are CMOS LST
designed for the remote controlled toy. The received signal is
amplified by the three-stage amplifier, and then the appropri-
ate amplified signal is sampled, fault-tolerantly checked and
decoded to control the actions of the remote-controlled
toy.There is an oscillator in all of the PT8A976 , PT8A976A
and PT8A976B. By adding an external resistor conveniently,
the oscillator will be constructed. The oscillator frequency
can be adjusted by the external resistor. Pressing the ON/OFF
button can control the output level of the PC pin.
Common features

•
Operating power-supply voltage range: 2.0 to 5.5V
Manual-powe-on/off with ON/OFF button
One output pin used for external power control
On-chip oscillator with an external resistor
On-chip reversing amplifiers
Low operating current
Few external components needed
Package: 16-pin DIP and 16-pin SOIC
PT8A976
PT8A976, the auto-power-off function is achieved by an in-
ternal counter. When the PT8A976 is powered on the counter
is reset and begin to count. Any received encoding signal also
reset the counter. The PC output pin will keep on a high level
until the counter counts up to about 6 minutes. The PC output
is used to control on/off state of the external power supply.
•
Four output pins for three functions
•
Auto-power-off if no signals received in 6 minutes
PT8A976A
•
Four output pins for three functions
•
Manual Power on/off function
PT8A976A/976B not provide auto-power-off function.
PT8A976B
•
•
Two output pins for three functions
Compatible with RX3 and MR3
PT8A976/976A have four output pins corresponding with the
three actions: Forward (Forward), Backward and Left.
PT8A976B has only two output pins corresponding with the
two actions: Forward and Backward.
