PT8A9781DE Datasheet (pt8a977b / Pt8a9781) Pt8a977b/9781 5-function Remote Controller For 1v Micro Cars

Manufacturer: Pericom Semiconductor (now Diodes Incorporated)

Overview: www.DataSheet4U.com Data Sheet PT8A977B/9781 5-Function Remote Controller for 1V Micro.

General Description

The PT8A977B and PT8A9781 provide a complete control functions to the remote-controlled toy.

The PT8A9781 has four output pins corresponding with the four actions i.e, forward, backward, right, left.

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.
