Description

The Intersil HCTS160MS 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 lowto-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.

The HCTS160MS 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 HCTS160MS is supplied in a 16 lead Ceramic flatpack

(K suffix) or a SBDIP Package (D suffix).
