Abstract
An improved current switch emitter follower (CSEF) latch has reduced 'noise' in the output signal from equal and opposite operation of the output transistors. The improvement resides in dotting the collector resistors of the input transistors in each current switch with a common shift resistor. The dotted collector resistors control the output transistors whereby one turns on and the other turns off with little change in output signal level as clock signals change to the input transistor.
