DESCRIPTION
The
M74HC693
is
an
high
speed
CMOS
DECADE/COUNTER
REGISTER
(3
STATE)
fabricated with silicon gate C2MOS technology.
The internal circuit is composed of 3 stages
including buffer output, which offers high noise
immunity
and
stable
output.
This
device
incorporates a synchronous counter, four bit
D-type register, and quadruple two-line to one-line
multiplexers with three-state outputs in a single 20
pin package. The counter can be programmed
from the data inputs and have enable P and
enable T inputs and a ripple carry output for easy
expansion. The register/counter select input, R/C,
selects the counter when low or the register when
high for the three state-outputs, QA, QB, QC, and
QD. If the LOAD input (LOAD) is held "L" DATA
input (A - D) are loaded into the internal counter at
positive edge of counter clock input (CCK). In the
counter mode, internal counter counts up at the
positive of the counter clock. If the counter clear
inputs (CCLR) is held "L", the internal counter is
cleared synchronously to the counter clock. The
internal counter’s outputs are stored in the output
register at the positive edge of the register clock
(RCK). If the register clear input (RCLR) is held "L"
the register is cleared synchronously to register
clock.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
