File Number
4628.1
Radiation Hardened Octal Transparent
Latch, Three-State
Intersil’s Satellite Applications Flow
TM
(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 HCTS373T 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.
