FLASHER IC
DESCRIPTION
The UTC UU4761 is a miconductor integrated circuit designed
for relay-controlled automotive flashers where a high level EMC is
required.
Lamp outage is indicated by frequency doubling during hazard
warning as well as direction mode.
FEATURES
* The static operating current<5mA
* Wide operating voltage range
* Very low susceptibility to EMI
