UCN4810A

The UCN4810A has the following features including Each Device Drives 10 Lines;60-V Output Voltage Rating;40-mA Output Source Current;High-Speed Serially-Shined Data Input CMOS-Compatible Inputs;Latches on Ail Driver Outputs;Designed to be Interchangeable with Sprague UCN4810A.The UCN4810A is a monolithic BIDFET integrated circuit designed to drive a dot matrix or segmented vacuum fluorescent display (VFD). This device features a serial data output to cascade additional devices for large display arrays.A 10-bit data word is serially loaded into the shift register on the positive-going transinons or me ciocK.Parallel data is transferred to the output buffers through a 10-bit D-type latch while the latch enable input is high and will be latched when the latch enable is low. When the blanking input is high, all outputs are low.Outputs are totem-pole structures formed by n-p-n emitter-follower and double-diffused MOS (DMOS) transistors with output voltage ratings of 60 volts, and 40 milliamperes source-current capability.All inputs are compatible with CMOS and TTL levels, but each requires the addition of a pull-up resistor VDD when driven by TTL logic.

The products UCN4810A described in this document are designed, developed and manufactured as contemplated for general use, including without limitation, ordinary industrial use, general office use, personal use, and household use, but are not designed, developed and manufactured as contemplated (1) for any use that includes fatal risks or dangers that, unless extremely high safety is secured, could have a serious effect to the public, and could lead directly to death, personal injury, severe physical damage or other loss (i.e., nuclear reaction control in nuclear facility, aircraft flight control, air traffic control, mass transport control, medical life support system, missile launch control in weapon system), or (2) for any use where chance of failure is intolerable (i.e., submersible repeater and artificial satellite).
