These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam  
during storage or handling to prevent electrostatic damage to the MOS gates.

(1) For operation in ambient temperatures above 25°C, the device must be derated based on a 150°C maximum junction temperature and a  
thermal resistance of 101°C/W junction to ambient for LM2907-8 and LM2917-8, and 79°C/W junction to ambient for LM2907-14 and  
LM2917-14.

(1) Hysteresis is the sum +VTH (VTH), offset voltage is their difference. See test circuit.  
(2) VOH is equal to ¾ × VCC 1 VBE, VOL is equal to ¼ × VCC 1 VBE therefore VOH VOL = VCC/2. The difference, VOH VOL, and the  
mirror gain, I2/I3, are the two factors that cause the tachometer gain constant to vary from 1.0.  
(3) Be sure when choosing the time constant R1 × C1 that R1 is such that the maximum anticipated output voltage at pin 3 can be reached  
with I3 × R1. The maximum value for R1 is limited by the output resistance of pin 3 which is greater than 10 MΩ typically.  
(4) Nonlinearity is defined as the deviation of VOUT (@ pin 3) for fIN = 5 kHz from a straight line defined by the VOUT @ 1 kHz and VOUT  
10 kHz. C1 = 1000 pF, R1 = 68k and C2 = 0.22 mFd.
