Description
The Intersil ACS161MS is a Radiation Hardened 4-Bit Binary Synchronous
Counter. 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 irrelevant to loading. TE low will keep TC low.
The ACS161MS 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 ACS161MS is supplied in a 16 lead Ceramic Flatpack (K suffix) or a
Ceramic Dual-In-Line Package (D suffix).

H = High Steady State, L = Low Steady State, h = High voltage level one setup time prior to the Low-to-High clock transition, I = Low volt-
age level one setup time prior to the Low-to-High clock transition, X = Don’t Care,q = Lower case letters indicate the state of the referenced
output prior to the Low-to-High clock transition,
= Low-to-High Transition.
NOTES:
1. The TC output is High when TE is High and the counter is at Terminal Count (HHHH).
2. The High-to-Low transition of PE or TE should only occur while ZCP is High for conventional operation.
3. The Low-to-High transition of SPE should only occur while CP is High for conventional operation.
4. The TC output is High when TE is High and the counter is at Terminal Count (HHHH).
