Description

The Intersil ACTS161MS is a Radiation Hardened 4-Bit Binary Syn-

chronous Counter, featuring asynchronous reset and load ahead

carry logic. The MR is an active low master reset. SPE is an active

low Synchronous Parallel Enable which disables counting and

allows data at the preset inputs (P0 - P3) to load the counter. CP is

the positive edge clock. TC is the terminal count or carry output.

Both TE and PE must be high for counting to occur, but are irrele-

vant to loading. TE low will keep TC low.

The ACTS161MS utilizes advanced CMOS/SOS technology to

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

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

The ACTS161MS is supplied in a 16 lead Ceramic Flatpack

(K suffix) or a Ceramic Dual-In-Line Package (D suffix).
