HCS373T
Data Sheet
July 1999
File Number
4617.1
Radiation Hardened Octal Transparent
Latch, Three-State
Intersil’s Satellite Applications
(SAF) devices are fully
tested and guaranteed to 100kRAD total dose. These QML
Class T devices are processed to a standard flow intended
to meet the cost and shorter lead-time needs of large
volume satellite manufacturers, while maintaining a high
level of reliability.
The Intersil HCS373T is a Radiation Hardened Octal
Transparent Three-State Latch with an active-low output
enable. The HCS373T utilizes advanced CMOS/SOS
technology. 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.
