At time of up- counting, CARRY and ZERO outputs are "H” Level at "000000", and at time of down counting, CARRY output is at "H" level at "999999" (for Tc5070P), "995959" ‘Te5071P), and "595999: (for TC5072P). When CARRY output is at "H" level, CARRY output remain at "H" leve until COUNT 11s, even if RESET and LOAD-C inputs are changed to "H" level. input For COUNT and UP/DOWN inputs is shaped schmitt trigger, COUNT and UP/DORN inputs rarely miscounts if waveform is not sharp. COMPARATOR OPERATION EQUAL output is provided at " with the comparator value set by LOAD-R input. However, even {f they concide each Jevel, when the contents of the counter coincide other during setting by LOAD-C and LOAD-R put, Output operation is inhibited and "L" Level remains unchanged. LOAD COUNTER AND LOAD REGISTER OPERATIONS When the data required to preset the counter or when the comprating value is Fequired to set to the register, such operation is made by LOAD-C and LOAD:R input. ‘The presetting of data to the counter is acquired by setting LOAD-C input to "H” level, synchronizing CA~CD input with the digit counter, and setting the digits ene after another. For the purpose, the external circuits are required for timing of D6~DI output with CA~CD input. The comprator value can be set to the register in the sane way. Load register operation is independently of counting operatiot therfore, even during setting of the data to the register, counting can be performed. (Sce an example of input setting circuits.) (ote) that normal operation 1s not acquired when the data exceeding the maximum counting value (for each digit) shown on page 1 for the individual items are set to the counter and register. LATCH OPERATION At STORE input is at "L" level, the contents of counter are straight transferred to the multiplexer, and the output indicates the contents of counter. At STORE input is at "A" level, the indicating output remains unchanged although the count varies for the contents of counter are latched at the positive edge of 559TC5070P, TC5071P, 1C5072P OPERATING CONSIDERATION (Cont'd) STORE input. When STORE is turned to "L" level, the contents of counter at that time are provided. STORE input shape schmitt trigger. 5. DISPLAY OPERATION " level, the higher order 5 digits of SEOMENT-OUT output are changed to the state of leading zero blanking. At “H" level, the function of leading zero blanking is released. At SEF input is at "L" lev blanking, and the di time, the BCD-OUT output provided che data of the 6th digit. At "Hl" level, the the SEGMENT-OUT output is changed to the state of counter is reset, and D6 (MSD) only is provided. At that DIGIT-OUT output provided in the order of D6, DS, D4, ... in synchronization with SCAN, and SECMENT-OUT and CD-OUT output are also provided in synchronization. Segment Display Format (Common Cathod type LED) {© OPERATION AUTO SCAN operation can be performed by inserting a capacitor between the terminal SCAN and the terminal Vss. By adding an external clock to the terminal SCAN, MANUAL SCAN operation can be performed. SCAN OSC actuates the digit counter, and at the AUTO SCAN operation, the digit blanking is applied to each DIGIT OUT for the 1/150 period of one cycle (T) of SCAN OSC, therfore, can be prevented overlap of each DIGIT OUT. One cycle of DIGIT OUT is equal to 6 cycles of SCAN OSC SCAN signal synchronize with data signal setting by the LOAD REGISTER and/or LOAD COUNTER inputs. An external capacitor of 2000 to 20000pF is‘ required for SCAN (Ho. (Note) BCD-OUT output may involve some hazards at the change of COUNT input and DIGIT-OUT output; However, such hazards do not hinder operation bec: they occur during the blanking hours for DIGIT-OUT and SECMENT-OUT output. 560TC5070P, TC5071P, T05072P OPERATING CONSIDERATION (Cont'd) SCAN 08C ProIt oor (ae) RECOMMENDED OPERATING CONDITIONS (vs, cuaracteetstic [| sywioL] Test conprrion MIN. wax.
