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 completely compatible 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 oOe to +70°C temperature range. connection diagram Vee INPUT STROBE D~TPUT INPUT STROBE OUTPUT *MllkenoconnlC1lo.
