DESCRIPTION

The μPD64A and 65 feature low-voltage 2.0 V operation, and incorporate a carrier generator for infrared remote control transmission, a standby release function through key entry, and a programmable timer, making them ideal for infrared remote control transmitters. A one-time PROM product, the μPD6P5 is also available for program evaluation or small-quantity production.
