CMOS IC

LC75700T

Key Scan IC

Overview

Package Dimensions

unit: mm

The LC75700T is a key scanning LSI that accepts input

from up to 30 keys and can control up to four general-

purpose output ports. Therefore it can reduce the number

of lines to the front panel in application systems.

3246-TSSOP20

[LC75700T]

6.5

Features

• Key input function for up to 30 keys.

• General-purpose output ports for up to four pins.

• A key scan is performed only when a key is pressed, and

thus power dissipation is reduced.

• Serial data I/O supports CCB format communication

with the system controller.

• Switching between the key scan output port and general-

purpose output port functions can be controlled by the

control data.

•

The RES pin is provided. This pin disables key scanning,

and forces the general-purpose output ports to the low

level.
