MM82C19 16-Line to 1-Line Multiplexer
October 1987
Revised January 2004
MM82C19
16-Line to 1-Line Multiplexer
General Description
The MM82C19 multiplex 16 digital lines to 1 output. A 4-bit
address code determines the particular 1-of-16 inputs
which is routed to the output. The data is inverted from
input to output.
A strobe override places the output of MM82C19 in the
high-impedance state.
All inputs are protected from damage due to static dis-
charge by diode clamps to V
CC
and GND.

“Absolute Maximum Ratings” are those values beyond which the
safety of the device cannot be guaranteed. Except for “Operating Tempera-
ture Range” they are not meant to imply that the devices should be oper-
ated at these limits. The Electrical Characteristic table provides conditions
for actual device operation.
