LC75742W

Ordering number : EN6142 CMOS IC LC75742E, 75742W 1/2 Duty VFD Driver with Key Input Function Overview The LC75742E and LC75742W are 1/2 duty VFD drivers that can be used for electronic tuning frequency display and other applications under the control of a microcontroller. These products can directly drive VFDs with up to 82 segments. It also includes a key scan circuit and can support input from up to 30 keys and can thus reduce the number of lines to the front panel in application systems. Package Dimensions unit: mm 3151-QFP64E [LC75742E] 17.2 14.0 0.35 33 48 49 32 1.0 1.6 1.0 0.8 1.6 1.0 0.15 Key input from up to 30 keys (Key scans are only performed when keys are pressed.) 82 segment outputs. Noise reduction circuits are built into the output drivers. Serial data I/O supports CCB format communication with the system controller. Dimmer and sleep mode can be controlled by serial data input. High generality since display data is displayed without the intervention of a decoder. All segments can be turned off with the BLK pin. 0.8 Features 17.2 14.0 17 1.0 64 1 16 3.0max 0.8 32 17 0.1 2.7 15.6 SANYO: QFP64E (QIP64E) unit: mm 3190-SQFP64 [LC75742W] 12.0 10.0 1.25 48 49 0.5 0.18 1.25 33 0.15 12.0 10.0 0.5 64 1.25 1 16 0.5 0.1 0.5 1.7max 1.25 SANYO: SQFP64 CCB is a trademark of SANYO ELECTRIC CO., LTD.
