Description
The Intersil ACS373MS 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.
The ACS373MS 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.
