1. General description

The 74HC75 is a quad bistable transparent latch with complementary outputs. Two latches are

simultaneously controlled by one of two active HIGH enable inputs (LE12 and LE34). When LEnn

is HIGH, the data enters the latches and appears at the nQ outputs. The nQ outputs follow the data

inputs (nD) as long as LEnn is HIGH (transparent). The data on the nD inputs one set-up time prior

to the HIGH-to-LOW transition of the LEnn will be stored in the latches. The latched outputs remain

stable as long as the LEnn is LOW. Inputs include clamp diodes. This enables the use of current

limiting resistors to interface inputs to voltages in excess of VCC.
