DM7822
DM7822 is dual line receiver manufactured by National Semiconductor.
description
The DM7822/DM8822 is a dual Inverting Ime receiver which meets the requirements of EIA specification RS232 Revision B. The device con- tams both receivers on a smgle monolithic silicon chip. The receivers share mon power supply and ground connections, otherwise their operation IS fully mdependent.
I n addition to meetmg the requirements of RS232, the DM7822/DM8822 also has Independent strobe mputs which allow the receiver to be placed In the high state Independent of the Information being received at tl;1e mput.
The output of the DM7822/DM8822 IS pletely patible with five volt DTL and TTL logic families
The DM7822 is specified for operation over the -55°C to +125°e military temperature range. The DM8822 is specified for operation over the o Oe to +70°C temperature range. connection diagram
