Active production, wide supply, low quiescent draw
The MC14511BDR2G is an active-production BCD-to-7-segment latch/driver from onsemi, designed to drive LED, LCD, or vacuum-fluorescent (VF) displays from a single 3 V to 18 V supply rail. Quiescent supply current is 10 µA typical — low enough that the driver itself does not dominate the power budget in a battery-backed display panel that stays lit continuously. The operating temperature range spans -55°C to 125°C, covering military/aerospace and industrial engine-bay environments where a commercial-grade driver would drop out.
Package, supply, and compliance for BOM placement
The 3 V to 18 V supply range means a single rail powers both the logic interface and the display segments — no separate regulator for the display supply in a 5 V or 12 V system. ROHS3 compliance clears the part for EU and global markets without a RoHS exemption expiry date to track.
