ACTS573T

Radiation Hardened Octal Three-State

Transparent Latch

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 ACTS573T is a Radiation Hardened Octal

Transparent Latch with an active low output enable. The

outputs are transparent to the inputs when the latch enable

(LE) is High. When the latch goes low the data is latched.

The output enable controls the three-state outputs. When

the output enable pins (OE) are high the output is in a high

impedance state. The latch operation is independent of the

state of output enable.
