Custom Monolithic Horizontal Lockout Logic IC: A 16-pin DIP custom circuit designed to handle multi-source timebase routing logic, collecting status loops from chop/alternate binaries and delay switches to resolve sweep lockout constraints. Unit Sourcing Compatibility: This component came out of the horizontal display control mainboards and master interlock modules of the Tektronix 11A11, 11B11, and 7000-series multi-plugin oscilloscope mainframes.
