Pin
Functions
Equivalent circuit
11
N2
Speed discriminator count switching
Low: 0 to 1.5 V
High: 4.0 V to VCC
An open state functions as a high-level input.
The hysteresis is about 0.45 V.
12
FGSOUT
FG amplifier output (after the Schmitt circuit)
This is an open collector output.
13
FGOUT
FG amplifier output
This pin is connected to the FG Schmitt comparator circuit
internally in the IC.
14
FGIN–
FG amplifier inverting input
15
FGIN+
FG amplifier noninverting input (1/2 VCC potential)
An initial reset is applied to the logic circuit block by
connecting an external capacitor (of about 0.1 μF) between
the FGIN+ pin and ground.
16 to 18
38 to 40
GND
Ground connections
These pins are all connected internally to the frame.
