Japan's Renesas Electronics agreed to buy U.S. chipmaker Integrated Device Technology (NSE: IDTI) for $6.7 billion, or $49 per share.

Why it's a big deal: Because it's an interesting test for U.S. and Chinese antitrust authorities, both of which have become reluctant to approve global semiconductor mergers.

Renesas has said it isn't worried, pointing to a lack of product overlap, but acquirers never express concern on announcement day.

Per Reuters' Makiko Yamazaki:

"Renesas has been keen to get its hands on IDT’s know-how in analog semiconductors for wireless networks and sensors — expertise crucial to develop autonomous driving and connected car technology."

Leopoldo López, a former political prisoner and prominent Venezuelan opposition leader, has left the country, his Popular Will party confirmed in a statement Saturday.

Why it matters: He's been highly influential in the push to oust President Nicolás Maduro's regime and a mentor to opposition leader Juan Guaidó. He'd been in the Spanish ambassador's Caracas residence since escaping house arrest in April 2019 following a failed military uprising.
