Mitsubishi M62261FP Datasheet
DESCRIPTION
PIN CONFIGURATION (TOP VIEW)
OSC
The M62261FP is a C-MOS semiconductor circuit for driving
MMIC, by connecting to the external capacitance, it can generate
2-times of inverting input voltage.
With resident charge-pump type 2-times inverting input voltage
circuit, -Vout and -2Vout can perform 2 kinds of negative source
system.
