Features
• QML Class T, Per MIL-PRF-38535
Intersil’s Satellite Applications FlowTM (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.
• Radiation Performance

- Single Event Upset (SEU) Immunity < 2 x 10
Errors/Bit-Day (Typ)
The Intersil HCTS160T is a Radiation Hardened High Speed
Presettable BCD Decade Synchronous Counter that
features an asynchronous reset and look-ahead carry logic.
Counting and parallel presetting are accomplished
• 3 Micron Radiation Hardened SOS CMOS
• Fanout (Over Temperature Range)
- Standard Outputs 10 LSTTL Loads
synchronously with the low-to-high transition of the clock. A
low level on the synchronous parallel enable input, SPE,
disables counting and allows data at the preset inputs, P0 -
P3, to be loaded into the counter. The counter is reset by a
low on the master reset input, MR. Two count enables, PE
and TE are provided for n-bit cascading. TE also controls the
terminal count output, TC. The terminal count output
indicates a maximum count for one clock pulse and is used
to enable the next cascaded stage to count.
• Significant Power Reduction Compared to LSTTL ICs
• DC Operating Voltage Range: 4.5V to 5.5V
• LSTTL Input Compatibility
