E910.52 Datasheet PDF - ELMOS Semiconductor AG

DESCRIPTION
The IC is intended to reduce the costs of products with a large number of inputs and also to reduce software overhead by generating an interrupt on pin change. To decrease the system power dissipation the external driver transistors are only active for 20µs of a 7ms frame corresponding to 140 Hz polling frequency.

FEATURES
► Supply range VDD 3.8V to 6V
► Supply range VS 5.5V to 18V
► Maximum over voltage protection up to 45V
► Low standby current (typical < 100µA)
► Parallel to serial interface
► High noise immunity
► Contact status monitoring by comparison to internal reference
► Interrupt request generated on debounced pin change
► Filtering of all inputs
► – 40°C to + 105°C operating temperature
► SO28w package

APPLICATION
► Automotive electronics
► Monitor for mechanical switches
► Monitor for voltage levels
