The PT8A9701 and PT8A973/973L is a pair of CMOS LSIs designed for remote controlled toy car application. They have seven control keys for controlling the corresponding motion (forward, backward, left, right, turbo and 2 functional keys) of the remote controlled car. They also have ‘Forward (Backward)’ and ‘Turbo’ combination application. Ordering Informatio.
• The PT8A9701 works as the encoder and the PT8A973/973L works as the decoder
• Seven output pins, 5 for forward, backward, left, right and turbo functions, and 2 functional keys
• Operation power supply for PT8A9701: 3V to 12V (with series resistor)
• Auto power-off if no key pressed (PT8A9701)
• Motor current limit to meet toy safety standard HD271 (PT8A973/973L)
• Low operating current
• On-chip oscillator with an external resistor
• On-chip reversing amplifiers
• Built-in 3.7V Zener (Vz) (PT8A973) and 3.1V Zener (Vz) (PT8A973L)
• Few external components needed
• Pin to pin compatible with.
