LM168/LM368 MOS sense amplifiers (MOS to TTL converters)
general description
This is a new series of hex sense amplifiers. The LM 165/
LM365 and LM166/LM366 have TRI·STATE outputs.
The LM167/LM367 and LM168/LM363 have both
TRI·STATE inputs and outputs. High impedance states
are controlled by an enable input.
The current threshold, at which the outputs change
state is determined by the current at the programming
pin. The current threshold is i OOIlA with the pro-
gramming pin grounded and 350llA with the pin
unconnected. It can be set from 100llA to 350llA by
connecting a resistor from the pin to ground, and set
,above 350llA by connecting a resistor from the pin to
the positive supply.
The outputs are high current drivers capable of sinking
50 mA in the low state and sourcing 5.0 mA in the
high state. The circuits feature high speed direct MOS
sense capability with high impedance states to allow
use of a common bus line.

ote1: "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. Except for "Operating
emperature Range" they are not meant to imply that the devices should be operated at these limits. The table of "Electrical Characteristics"
rovides conditions for actual device operation.
ot.2: Unless otherwise specified min/max limits apply across the -55°e to +125°e temperature range for the LM165, LM166, LM167, LM168
,d across the 0° e to +70° e range for the LM365, LM366, LM367, LM368. All typicals are given for Vee = 7.0V and TA = 25° e.
ate 3: All currents into device PinS shown as positive, out of device pms as negative. All voltages referenced to ground unless otherwise noted. All
Ilues shown as max or min on absolute value basIs.
ote 4:' Only one output at a time should be shorted.
