The inverting input logic (VIL=1V, VIH=2V) and independent channel architecture allow the two outputs to be driven from separate PWM signals or paralleled for higher output current. Supply voltage spans 4V to 15V, covering common 5V and 12V gate-drive rails without an extra regulator.

Frequently asked questions
What is the replacement for UCC27423DRG4?
No official TI successor is listed for the UCC27423DRG4. The UCC27424DRG4 (non-inverting input variant) shares the same package and pinout but differs in input polarity — verify the logic sense before substituting. For a drop-in replacement with the same inverting inputs, consider the UCC27423D (SOIC-8, active) or the UCC27423QDG4Q1 (automotive-qualified, active), both from TI.
