Overview

www.DataSheet.co.kr MOTOROLA SEMICONDUCTOR TECHNICAL DATA M u Iti-Character lED CMOS The MC144898 is a flexible light-emitting-diode driver which directly interfaces to individual lamps, 7-segment displays, or various combinations of both.

LEOs wired with common cathodes are driven in a multiplexed-by-5 fashion.

Communication with an MCUIMPU is established through a synchronous serial port.

Key Features

data retention plus decode and scan circuitry, thus relieving processor overhead. A single, current-setting resistor is the only ancillary component required. A single device can drive anyone of the following: a 5-digit display plus decimals, a 4-112-digit display plus decimals and sign, or 25 lamps. A special technique allows driving 5 112 digits; see Figure 16. A configuration register allows the drive capability to be partitioned off to suit many additional.
