Hex LED Digit Driver
Description:
The NTE2027 is an interface circuit in a 14–Lead DIP typ package designed to be used in conjunction
with MOS integrated circuits and common cathode LED’s in serially addressed multi–digit displays.
The number of drivers required for this time–multiplexed system is minimized as a result of the seg-
ment–address–and–digit–scan method of LED drive.
Features:
D Sink Capability Per Driver: 350mA
D MOS Compatibility (Low Input Current)
D Low Standby Power
D High–Gain Darlington Circuits

Note 1. “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot
be guaranteed. Except for “Operating Temperature Range” they are not meant to imply that
the device should be operated at these limits. The table of “Electrical Characteristics” pro-
vides conditions for actual device operation.
Note 2. The input is the only device pin which may be negative with respect to GND.
