7 / 30 page DataSheet S14791EJ1V0DS 5 µµµµPD16721 (2/2) Pin Symbol Pin Name I/O Description MODE Output reset control I MODE = H or open: Output reset MODE = L: No output reset MODE is pulled up to the VDD1 in the LSI. POL21, POL22 Data inversion I Select of inversion or no inversion for input data. POL21: Data inversion or no inversion of Port1. POL22: Data inversion or no inversion of Port2 POL21/22 = H: Data are inverted in the LSI. POL21/22 = L: Data are not inverted in the LSI. VSEL Driver voltage select I The driver voltage can be switched by controlling the stationary bias current of the output amplifier via VSEL. VSEL = H: VDD2 = 13.0 V (large bias current) VSEL = L or open: VDD2 = 15.0 V (small bias current) LPC is pulled down to the VSS1 in the LSI. V0 to V15 γ -corrected power supplies − Input the γ -corrected power supplies from outside by using operational amplifier. During the gray scale voltage output, be sure to keep the gray scale level power supply at a constant level. Make sure to maintain the following relationships. VDD2–0.2 V ≥ V0 > V1 > V2 > ....... > V6 > V7 ≥ 0.5 VDD2 + 0.5 V 0.5 VDD2–0.5 V ≥ V8 > V9 > V10 > ....... V14 > V15 ≥ VSS2 + 0.2 V TEST Test I Normally, set the TEST pin to high level or leave open. This pin is pulled up to VDD1 in the LSI. VDD1 Logic power supply − 2.5 to 3.4 V VDD2 Driver power supply − 13.0 ± 0.5 V or 15.0 ± 0.5 V VSS1 Logic ground − Grounding VSS2 Driver ground − Grounding Cautions 1. The power start sequence must be VDD1, logic input, and VDD2 & V0 to V15 in that order. Reverse this sequence to shut down. 2. To stabilize the supply voltage, please be sure to insert a 0.47 µµµµF bypass capacitor between VDD1 to VSS1 and VDD2 to VSS2. Furthermore, for increased precision of the D/A converter, insertion of a bypass capacitor of about 0.1 µµµµF is also advised between the γγγγ-corrected power supply terminals (V0, V1, V2,....., V15) and VSS2. 5 5 |
