Description
The Intersil ACTS373MS is a radiation hardened octal transpar-
ent 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.
The ACTS373MS utilizes advanced CMOS/SOS technology to
achieve high-speed operation. This device is a member of the
radiation hardened, high-speed, CMOS/SOS Logic Family.
