NTE6885 thru NTE6888
Integrated Circuit
Hex 3–State Buffer/Inverter
Description:
The NTE6885 thru NTE6888 series of devices combines three features usually found desirable in
bus–oriented systems: 1) High impedance logic inputs insure that these devices do not seriously load
the bus; 2) Three–state logic configuration allows buffers not being utilized to be effectively removed
from the bus; 3) Schottky technology allows high–speed operation.
While the NTE6885 to NTE6888 are all buffers, the devices differ in that the NTE6885 (non–inverting)
and the NTE6886 (inverting) provide a two–input Enable which controls all six buffers, while the
NTE6887 (non–inverting) and the NTE6888 (inverting) provide two Enable inputs; one controlling
four buffers and the other controlling the remaining two buffers.
These units are well–suited for Address buffers on the M6800 or similar microprocessor application.
Features:
High Speed: 8.0ns (Typ)
Three–State Logic Configuration
Single +5V Power Supply Requirement
Compatible with 74LS Logic or 6800 Microprocessor Systems
High Impedance PNP Inputs Assure Minimal Loading of the Bus
