Features
• The PT8A9702 works as the encoder and the
PT8A973/974/973L/974L works as the decoder
• 8-direction control
• Operation power supply for PT8A9702: 3V to 12V
(with series resistor)
• Auto power-off if no key pressed (PT8A9702)
www.DataSheet4UM.coomtor current limit to meet toy safety standard
HD271 (PT8A973/974/973L/974L)
• Low operating current
• On-chip oscillator with an external resistor
• On-chip reversing amplifiers
• Built-in 3.8V Zener (9702), 3.7V Zener (Vz)
(973/974) and 3.1V Zener (Vz) (973L/974L)
• Few external components needed
• Pin to pin compatible with TX6/RX6
General Description
The PT8A9702P works as encoder, it can provide 8-
direction remote control for toy car application with
PT8A973/973L/PT8A974/974L together. Input 8-
direction named F, FL, L, BL, BR, R, FR, and B they
are combined with F, L, B, and R four signals. In
decoder side, use output signal Left & Right to drive
Right Motor, and use For & Back to drive Left Motor.
Their detail relations please see truth table.
