NT7704

www.datasheet4u.com NT7704 240 Output LCD Segment/Common Driver Features (Segment mode) ! Shift Clock frequency: 20 MHz (Max.) (VDD = 5 V ± 10%) 12 MHz (Max.) (VDD = 2.5V - 4.5V) ! Adopts a data bus system ! 4-bit/8-bit parallel input modes are selectable with a mode (MD) pin ! Automatic transfer function with an enable signal ! Automatic counting function when in "chip select" mode, which causes the internal clock to be stopped by automatically counting 240 bits of input data (Common mode) ! Shift clock frequency : 4.0 MHz (Max.) ! Built-in 240-bits bidirectional shift register (divisible into 120-bits x 2) ! Available in a single mode (240-bits shift register) or in a dual mode(120-bits shift register x 2) 1. Y1 → Y240 Single mode 2. Y240 → Y1 Single mode 3. Y1 → Y120, Y121 → Y240 Dual mode 4. Y240 → Y121, Y120 → Y1 Dual mode The above 4 shift directions are pin-selectable (Both for segment mode and common mode) ! ! ! ! ! ! ! Supply voltage for LCD driver: 15.0 to 30.0 V Number of LCD driver outputs: 240 Low output impedance Low power consumption Supply voltage for the logic system: +2.5 to +5.5 V COMS process Package: Gold bump die / 272 Pin TCP(Tape Carrier Package) ! Not designed or rated as radiation hardened General Description The NT7704 is a 240-bit output segment/common driver LSI suitable for driving large scale dot matrix LCD panels used by PDA's, personal computers and work stations for example. Through the use of COG technology, it is ideal for substantially d...
