Sanyo Electric LC79400D
The LC79400D is a large-scale dot matrix LCD segment driver LSI. The LC79400D can be used in conjunction with common driver LC7943D (QIP80D) as well as LC79430D (QIP100D) and LC79431D (QIP100D) to drive a widescreen LCD panel. The voltages V1, V3, V4, V7, VDD and VEE must obey the relationships: VDD ≥ V1 > V3 > V4 > VEE, VDD – V3 ≤ 7V, V4 – VEE ≤ 7V.| Part No. | LC79400D |
