Current hogging injection logic: new functionally integrated circuits

A new approach involving functionally integrated logic - Current Hogging Injection Logic (CHIL) - combines the input flexibilityo f CHL with the performance and packing density of 12L, and is fully compatible with 12L circuits. operated output NPN transistor can be turned off by applying a LO level voltage (<300 mV) to either input I1 or 12. If both inputs are turned off, the output transistor is in the on-state, since current ho=ing3 takes place between the injecting emitter E and the floating control collectors I1 and I2 (HI level >400 mV) of the lateral PNP transistor.
