Description
The Intersil ACTS373MS is a radiation hardened octal transparent latch with three-state outputs. The outputs are transparent to the inputs when the latch enable (LE) is high. When the LE goes low, the data is latched. When the Output Enable (OE) is high, the outputs are in the high impedance state. The latch operation is independent of the state of the output enable.
