DM7556DM8556 TRI-STATE
Programmable
Binary Counters
General Description
These circuits are synchronous edge-sensitive fully-pro-
grammable 4-bit counters The counters feature both con-
ventional totem-pole and TRI-STATE outputs such that
when the outputs are in the high impedance mode they can
be used to enter data from the bus lines In addition the
clear input operates completely independent of all other in-
puts During the programming operation data is loaded into
the flip-flops on the positive-going edge of the clock pulse
To facilitate cascading of these counters the MAX COUNT
output can be tied directly into the count enable input of the
next counter

The IO pins are used as inputs when they are TRI-STATED and the LOAD input is Low They are outputs and active
when LOAD input is High and OD is Low
H e High Level (Steady State)
L e Low Level (Steady State)
X e Don’t Care including transitions
a b c d e The level of the steady state input at inputs A B C D respectively
QA0 QB0 QC0 QD0 e The level of QA QB QC QD respectively before the indicated steady state input conditions
were established
