DEVICE CONNECTIONS *
COUNT (A) - CMOS, Schmidt Trigger; used as count or
count control input, depending on the mode of operation
selected. It’s generally used as a count input. See Modes
of Operation for more details.
COUNT (B) - CMOS, Schmidt Trigger; used as count or
count control input, depending on the mode of operation
selected. It’s generally used as a count control input. See
Modes of Operation for more details.
RESET (R) - CMOS Schmidt trigger; counter is reset and
held to zero when this pin is at a low level.
INHIBIT (I) - CMOS Schmidt trigger; all counting for all
modes is inhibited when this input is at a low level. This
input is asynchronous with inputs “A” and “B”.
LATCH (L) - CMOS Schmidt trigger; data on the display is
latched when this input is at a high level. This input has no
effect on the counting operations of the unit and is
asynchronous with inputs “A” and “B”
DP1, DP2, DP3 - CMOS level-sensitive; these inputs are
used for decimal point selection and leading zero blanking
selection. See Decimal Point and Leading Zero Blanking
Selection for more details.
MS1, MS2, MS3, MS4, MS5, MS6 - CMOS level-sensitive;
these inputs are used for Mode Selection. These modes
include: Bi-Directional Counting, Quadrature Counting,
Anti-Coincidence Summing and Anti-Coincidence
Add/Subtract. See Modes of Operation for more details.
OSC. - This input provides for connection of an external 2.4
meg. resistor required by the on-board scan oscillator. The
oscillator operates at 240 Hz ±35% and has an internal
divider to provide 60 Hz back plane drive.
V DD - 2.5 to 6 VDC Supply
V SS - Common for D.C. Supply and Inputs.
* All other inputs must be tied to either V DD or V SS ,
whichever is appropriate.
BLOCK DIAGRAM
CAUTION
This device contains CMOS circuitry which requires special anti-static
handling to the same degree required by standard CMOS integrated circuits.
Units should be stored in the conductive packaging used to ship the devices.
Containers should be opened and units handled only on a conductive table
