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 discharge by diode clamps to VCC and GND.
Features
s Wide supply voltage range: 3.0V to 15V s Guaranteed noise margin: 1.0V s High noise immunity: 0.45 VCC (typ.) s TTL compatibility: Drive 1 TTL Load

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 devices should be operated at these limits. The Electrical Characteristic table provides conditions for actual device operation.
