HCTS190MS  
Radiation Hardened  
Synchronous 4-Bit Up/Down Counter  
September 1995  
Features  
Description  
• 3 Micron Radiation Hardened CMOS SOS  
The Intersil HCTS190MS is an asynchronously presettable  
BCD Decade synchronous counter. Presetting the counter to  
the number on the preset data inputs (P0 - P3) is accom-  
plished by a low on the parallel load input (PL). Counting  
occurs when (PL) is high, Count Enable (CE) is low and the  
Up/Down (U/D) input is either low for up-counting or high for  
down-counting. The counter is incremented or decremented  
synchronously with the low-to-high transition of the clock.  
• Total Dose 200K RAD (Si)  
• SEP Effective LET No Upsets: >100 MEV-cm2/mg  
• Single Event Upset (SEU) Immunity < 2 x 10-9 Errors/  
Bit-Day (Typ)  
• Dose Rate Survivability: >1 x 1012 RAD (Si)/s  
• Dose Rate Upset >1010 RAD (Si)/s 20ns Pulse  
• Latch-Up Free Under Any Conditions  
When an overflow or underflow of the counter occurs, the  
Terminal Count output (TC), which is low during counting,  
goes high and remains high for one clock cycle. This output  
can be used for look-ahead carry in high speed cascading.  
The TC output also initiates the Ripple Clock output (RC)  
which, normally high, goes low and remains low for the low-  
level portion of the clock pulse. These counter can be cas-  
caded using the Ripple Carry output.  
• Fanout (Over Temperature Range)  
- Standard Outputs - 10 LSTTL Loads  
• Military Temperature Range: -55oC to +125oC  
• Significant Power Reduction Compared to LSTTL ICs  
• DC Operating Voltage Range: 4.5V to 5.5V  
If the decade counter is preset to an illegal state or assumes  
an illegal state when power is applied, it will return to the  
normal sequence in one or two counts  
• LSTTL Input Compatibility  
- VIL = 0.8V Max  
The HCTS190MS utilizes advanced CMOS/SOS technology  
to achieve high-speed operation. This device is a member of  
radiation hardened, high-speed, CMOS/SOS Logic Family.  
- VIH = VCC/2 Min  
• Input Current Levels Ii 5µA @ VOL, VOH  
The HCTS190MS is supplied in a 16 lead Ceramic flatpack  
(K suffix) or a SBDIP Package (D suffix).
