HCTS160T
Data Sheet July 1999 File Number
Radiation Hardened Synchronous
Counter
Intersil’sSatellite 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.
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
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 providedfor 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.
Specifications
Specifications for Rad Hard QML devices are controlled by
the Defense Supply Center in Columbus (DSCC). The SMD
numbers listed below must be used when ordering.
Detailed Electrical Specifications for the HCTS160T are
contained in SMD 5962-95742. A “hot-link” is provided from
our website for downloading.

H = HIGH voltage level.

h = HIGH voltage level one setup time prior to the LOW-to-HIGH clock transition.
l = LOW voltage level one setup time prior to the LOW-to-HIGH clock transition.
X = Immaterial.
q = Lower case letter indicate the state of the referenced output prior to the LOW-to-HIGH clock transition.

NOTES:
1. The TC output is HIGH when TE is HIGH and the counter is at terminal count (HHHH for 161 and HLLH for 160).
2. The HIGH-to-LOW transition of PE or TE on the 54/74161 and 54/74160 should only occur while CP is high for conventional operation.
3. The LOW-to-HIGH transition of SPE on the 54/74161 and 54/74160 should only occur while CP is high for conventional operation.
