LC79400D

No. 4346-2/8

Allowable Operating Ranges at Ta = –20 to +75°C, VSS = 0 V

Note:2. The voltages V1, V3, V4, V7, VDD and VEE must obey the relationships: VDD ≥ V1 > V3 > V4 > VEE, VDD – V3 ≤ 7V, V4 – VEE ≤

7V.

3. When applying power, apply power to the LCD drive block after applying power to the logic block or apply power to both the blocks

simultaneously. When turning off power, turn off power to the logic block after turning off power to the LCD drive block or turn

off power to both the blocks simultaneously.

Electrical Characteristics at Ta = 25±2°C, VSS = 0 V, VDD = 5 V±10%

Note:4. VDE = V1 or V3 or V4 or VEE, V1 = VDD, V3 = 15/17 (VDD-VEE), V4 = 2/17 (VDD-VEE)

5. ISS current flows from VDD to VSS.

6. IEE current flows from VDD to VEE.
