DESCRIPTION
As a completely self-contained counter/display module, SCUB1/SCUB2 (5 V) and SCUB1LV (3.3 V) can be treated like an I.C. The module contains a custom counter/driver chip that performs all the counting functions together with a 6-digit LCD readout. The latchable display with the separate reset function permits the module to be used as frequency or rate meter, timer, phase-angle or pulse width indicator and for other complex readout requirements in addition to simple high speed counting.
The module is ideal for internal “on-board” applications where a readout of count, frequency, time, etc. is needed within a circuit enclosure for

SUB-CUB 1 - 0.2" (5 mm) HIGH DISPLAY
SUB-CUB 2 - 0.35" (8.9 mm) HIGH DISPLAY
SOLDERLESS, ELASTOMERIC INTERCONNECTS
ULTRA-LOW POWER
5 V: SUB-CUB 1 AND 2
3.3 V: SUB-CUB 1 ONLY
LATCHABLE DISPLAY WITH LEADING ZERO BLANKING
COUNT RATES TO 10 KHz
IDEAL IN APPLICATIONS FOR:
REGISTER, STATUS & USAGE COUNTING FREQUENCY, EPUT, & RPM INDICATION TIMER, PULSE-WIDTH & PERIOD READOUT
maintenance, diagnostic, tune-up, or other data readout requirements. The SUB­CUB 2, with its larger display, can also be mounted with the convenient bezel kit to provide a very flexible and econmical panel instrument.
SUB-CUBs snap-mount directly on any 1/16" P.C. board that has been etched to provide a mating interconnect pad pattern with two mounting holes and a polarizing “key” hole. Interconnections to the P.C. Board as well as internal connections are made with elastomeric connectors that provide corrosion-proof, gas tight, interface contacts for high reliability.
MOUNTING & DIMENSIONS
Snap in mounting on the P.C. Board is facilitated by two, split, lock-ramp pins which engage mounting holes drilled in the P.C. Board. The silicone rubber elastomeric connectors compress to accommodate P.C. Board thickness variation of ±0.005" (0.13 mm).

P.C. BOARD LAYOUT
P.C. Board pads may be gold or tin-lead plated. Pad surface must be flat
without excessive tin-lead build-up. (Layout views are from SUB-CUB
mounting side of board.)

BLOCK DIAGRAM
COUNT (C) - CMOS, Schmidt Trigger; counter increments on negative going
transition.
RESET (R) - CMOS, Schmidt Trigger; counter is reset to zero when input is
low. Counter should always be reset to zero whenever power is first applied to the unit.
LATCH (L) - CMOS, Schmidt Trigger; when pulled low, the latches are
transparent and display is updated as new counts are received. When latch input is pulled high, the display registers count existing immediately prior to activating the latch.
TEST (T) - CMOS, Schmidt Trigger; Input must be connected to VDD. This
input is used by manufacturer during factory testing.
VDD - +VDC Supply.
VSS - Common for D.C. Supply and Inputs.
* All unused inputs must be tied to either VDD or VSS, 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
