A low-voltage latch adapted for differential mode with a supply voltage of 2.5V and a voltage swing of 200mV to 300mV is described. Two inverters are used, each having a non-inverting and an inverting input terminal and a non-inverted and an inverted output terminal. The non-inverted output terminals are connected to the input of an OR structure, and the inverted output terminals are connected to the input of another OR structure. The input terminals of one inverter form the input terminals of the latch. The input terminals of the other inverter are connected to the output terminals of the OR structures and form the output of the latch. The supply voltages of the inverters are varied, so that at any given time, only one inverter has an appropriate supply voltage. This inverter then controls the output of the latch. In this way, a latch function is achieved.
