SN75556 - Electroluminescent Column Drivers

Download the SN75556 datasheet PDF. This datasheet also covers the SN75555 variant, as both devices belong to the same electroluminescent column drivers family and are provided as variant models within a single manufacturer datasheet.

Description

The SN65555, SN75555, SN65556, and SN75556 are monolithic BIDFET† integrated circuits designed to drive the column electrodes of an electroluminescent display.

The SN65556 and SN75556 output sequence is reversed from the SN65555 and SN75555 for ease in printed-circuitboard layout.

Each Device Drives 32 Electrodes 90-V Output Voltage Swing Capability Using Ramped Supply 15-mA Output Source and Sink Current Capability High-Speed Serially-Shifted Data Input Totem-Pole Outputs Latches on All Driver Outputs description The SN65555, SN75555, SN65556, and SN75556 are monolithic BIDFET† integrated circuits designed to drive the column electrodes of an electroluminescent display. The SN65556 and SN75556 output sequence is reversed from the SN65555 and SN75555 for ease in printed-circuitboard layout. The devices consist of a 32-bit shift register, 32 latches, and 32 output AND gates. Serial data is entered into the shift register on the low-to-high transition of CLOCK. When high, LATCH ENABLE transfers the shift register contents to the outputs of the 32 latches.
