DESCRIPTION
The ACT163 is a high-speed CMOS
SYNCRONOUS PRESETTABLE COUNTER
fabricated with sub-micron silicon gate and
double-layer metal wiring C2MOS technology. It is
ideal for low power applications mantaining high
speed operation similar to eqivalent Bipolar
Schottky TTL. It is a 4 bit binary counter with
Synchronous Clear.
The circuits have four fundamental modes of
operation, in order of preference: synchronous
reset, parallel load, count-up and hold. Four
control inputs, Master Reset (CLEAR), Parallel
PIN CONNECTION AND IEC LOGIC SYMBOLS

ORDER CODES :

74ACT163M
Enable Input (LOAD), Count Enable Input (PE)
and Count Enable Carry Input (TE), determine
the mode of operation as shown in the Truth
Table. A LOW signal on CLEAR overrides
counting and parallel loading and allows all
output to go LOW on the next rising edge of
CLOCK. A LOW signal on LOAD overrides
counting and allows information on Parallel Data
Qn inputs to be loaded into the flip-flops on the
next rising edge of CLOCK. With LOAD and
CLEAR, PE and TE permit counting when both
are HIGH. Conversely, a LOW signal on either
PE and TE inhibits counting.
The device is designed to interface directly High
Speed CMOS systems with TTL, NMOS and
CMOS output voltage levels.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
