Description

The Intersil HCS160MS 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 syn-

chronous 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 out-

put, TC. The terminal count output indicates a maximum

count for one clock pulse and is used to enable the next cas-

caded stage to count.

The HCS160MS utilizes advanced CMOS/SOS technology

to achieve high-speed operation. This device is a member of

radiation hardened, high-speed, CMOS/SOS Logic Family.

The HCS160MS is supplied in a 16 lead Ceramic flatpack (K

suffix) or a SBDIP Package (D suffix.)
