DEVICE CONNECTIONS *
SIG - CMOS input with series 4.7 K resistor.
Timer Modes - SUB-CUB-T accumulates time when SIG is at V DD ,
SUB-CUB-T stops timing when SIG is at V SS .
Counter Modes - SUB-CUB-T increments a count on the rising edge of
the SIG input.
C0-C3 - CMOS latched inputs. These inputs select the mode of operation of
the SUB-CUB-T. Refer to “MODE SELECTION”.
WINK - CMOS output. Connect this output to either DP1 or DP2 input to
enable a decimal point.
DP1 - LCD input. Connect this input to the WINK output to enable the first
position decimal point. Connect to BP to disable this decimal point.
DP2 - LCD input. Connect this input to the WINK output to enable the
second position decimal point. Connect to BP to disable this decimal
point.
BP - CMOS output. Connect this output to either DP1 or DP2 to disable a
decimal point.
V DD - 2.5 to 5.5 VDC supply.
V SS - Common for D.C. Supply and Inputs.
* All unused inputs must be tied to V SS or V DD , whichever is appropriate.

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
top by personnel wearing wrist-strap grounding equipment. These devices
have the same protection circuits as standard CMOS devices to prevent

* An internal 4.7 K series resistor will protect the SIG input from input voltages up to 9.7 V AC or DC (w/V DD = 5.0).
At higher input voltages, an external resistor should be used to limit the input current to less than 1 mA.
** Inputs C0-C3 are latched internally and will draw little or no current after switching. During switching, a 90 μA peak
current may be drawn for up to 10 nS.
