Description
The Intersil HCTS373MS is a Radiation Hardened octal transparent three-state latch with an active-low output enable. The outputs are transparent to the inputs when the Latch Enable (LE) is
HIGH. When the Latch Enable (LE) goes LOW, the data is
latched. The Output Enable (OE) controls the three-state outputs.
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 HCTS373MS utilizes advanced CMOS/SOS technology to
achieve high-speed operation. This device is a member of
radiation hardened, high-speed, CMOS/SOS Logic Family.
