Product Details

ROHM's low voltage CMOS comparators (BU7251, BU7231, BU7252, and BU7232) integrate input full swing / push-pull output functionality and 1 or 2 circuits on single chip. A low operating voltage range of between 1.8V and 5.5V (single supply configuration) and low current consumption with ultra-low input bias current make them suitable for a wide variety of applications.

Low operating supply voltage (+1.8[V]~+5.5[V])
+1.8 [V]~+5.5[V](single supply)
±0.9[V]~±2.75[V](split supply)
Input and Output full swing
Push-pull output type
High speed operation
Internal ESD protection
Human body model (HBM) ±4000[V](Typ.)
Wide temperature range
