NTE922, NTE922M, & NTE922SM
Integrated Circuit
Voltage Comparator
Description:
The NTE922, NTE922M, and NTE922SM are voltage comparators that have input currents nearly
a thousand times lower than devices like the NTE910 or NTE910D. They are also designed to operate
over a wider range of supply voltages: from standard
±15V op amp supplies down to the single 5V
supply used for IC logic. Their output is compatible with RTL, DTL and TTL as well as MOS circuits.
Further, they can drive lamps or relays, switching voltages up to 50V at currents as high as 50mA.
Both the input and the output of these devices can be isolated from system ground, and the output
can drive loads referred to ground, the positive supply or the negative supply. Offset balancing and
strobe capability are provided and outputs can be wire OR’ed. Although slower than the NTE910 and
NTE910D (200ns response time vs 40ns) the devices are also much less prone to spurious oscilla-
tions.
Features:
D Operates from single 5V supply
D Input current: 150nA max. over temperature
D Offset current: 20nA max. over temperature
D Differential input voltage range: ±30V
D Power consumption: 135mW at ± 15V
D Available in 3 Different Case Styles:
8–Lead Metal Can: NTE922
8–Lead Mini DIP: NTE922M
8–Lead SOIC (Surface Mount): NTE922SM

Note 1. This rating applied for
±15V supplies. The positive input voltage limit is 30V above the nega-
tive supply. The negative input voltage limit is equal to the negative supply voltage or 30V
below the positive supply, whichever is less.
Note 2. The maximum junction temperature is 110
°C. For operating at elevated temperature, the
NTE922 must be derated based on a thermal resistance of 150
°C/W, junction–to–ambient,
or 45
°C/W, junction–to–case. The thermal resistance of the NTE922M and the NTE922SM
is 100
°C/W, junction–to–ambient.
