NTE8212
Integrated Circuit
Schottky, 8鈥揃it Input/Output Port
Description:
The NTE8212 input/output port is an integrated circuit in a 24鈥揕ead DIP type package and consists
of an 8鈥揵it latch with three鈥搒tate output buffers along with control and device selection logic. Also
included is a service request flip鈥揻lop for the control and generation of interrupts to the microprocessor.

Note 1. Stress above those listed under 鈥淎bsolute Maximum Ratings鈥?may cause permanent dam-
age to the device. This is a stress rating only and functional operation of the device at these
or any other conditions above those indicated in the operational sections of this specification
is not implied. Exposure to absolute maximum rating conditions for extended periods may
affect device reliability.
