MC14489BP General Description

The MC14489BP is a versatile 4x7-Key Matrix Scan IC designed for applications requiring keypad input, featuring a 28-key scanning array organized in a 4x7 matrix. Its built-in debounce circuitry ensures accurate key detection, while the serial interface allows for convenient communication with external devices or microcontrollers. With a voltage range of 2.0V to 5.5V, it is suitable for a wide range of electronic devices, making it a highly adaptable and versatile choice. Its low standby current consumption of less than 1uA furthers its appeal, offering energy efficiency and prolonged battery life, particularly in battery-operated applications

Key Features

Multy-Character LED Display/Lamp Driver CMOS

The MC144898 is a flexible light-emitting-diode driver which directly in terfaces 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. The MC 144898 features data retention plus decode and scan circuitry, thus relieving processor overhead. A single, current-setting resistor is the only ancillary component required.
