0.180 4-Character 5x7 Dot Matrix Serial Input Dot Addressable Intelligent Display Devices Lead (Pb) Free Product / RoHS Compliant SCE574x SCE574xP-SIP SCE574xQ-SIP with right angle bends Standard Red SCE5740 Yellow SCE5741 Super-red SCE5742 Green SCE5743 High Efficiency Green SCE5744 Orange SCE5745 DESCRIPTION ALSO AVAILABLE WITH OPTIONS (see page 8) The SCE574x is a four digit, dot addressable 5 x 7 dot SCE574xP-SIP matrix, serial input, alphanumeric Intelligent Display SCE574xQ-SIP with right angle bends device. The four digits are packaged in a rugged, high quality, optically transparent, plastic 14 pin DIP with 2.54 mm (0.1 ) pin spacing. FEATURES The SCE574xP is a SIP version of SCE574x. The Four 4.57 mm (0.180 ) 5 x 7 Dot Matrix Characters in SCE574xQ is also a SIP version of the SCE574x but the Red, Yellow, Super-red, Green, High Efficiency Green, leads are at right angles to the package so that the part Orange can be mounted vertically. The SIP version parts have Optimum Display Surface Efficiency only 7 pins. The SIP parts do not have the option of using (display area to package ratio) an external clock. All the electrical descriptions for the High Speed Data Input Rate: 5.0 MHz SCE574x apply to the SIP versions except the allusions ROMless Serial Input, Dot Addressable Display to the external clock. Ideal for User Defined Characters Built-in Decoders, Multiplexers and LED Drivers The on-Board CMOS has a 140 bit RAM, one bit associ- Wide Viewing Angle, X Axis 55, Y Axis 55 ated with one LED, each to generate User Defined Char- acters. In Power Down Mode, quiescent current ATTRIBUTES is < 50 A. 140 Bit RAM for User Defined Characters The SCE574x is designed for work with the serial port of Eight Dimming Levels plus eight fine dimming lev- most common microprocessors. Data is transferred into els. the display through the Serial Data Input (DATA), clocked Power Down Model (< 250 mW) by the Serial Data Clock (SDCLK), and enabled by the Hardware/Software Clear Functions Load Input (LOAD). External Clock-SCE574x only The SCE574x Clock I/O (Clk I/O) and Clock Select (CLK- SEL) pins offer the user the capability to supply a high speed external multiplex clock. This feature can minimize audio in-band interference for portable communication equipment or eliminate the visual synchronization effects found in high vibration environments such as avionic equipment. A divide by 16 prescalar is built into the part and can be accessed by software to reduce the multiplex frequency if a high speed external clock is used. 2006-03-30 1SCE5740, SCE5741, SCE5742, SCE5743, SCE5744, SCE5745 Ordering Information Type Color of Emission Character Height Ordering Code mm (inch) SCE5740 standard red Q68100A1369 SCE5741 yellow Q68100A1370 SCE5742 super-red Q68100A1371 4.57 (0.180) SCE5743 green Q68100A1372 SCE5744 high efficiency green Q68100A1373 SCE5745 orange Q68100A1374 Package Outlines Dimensions in mm (inch) 19.91 (0.784) IDOD5006 2006-03-30 2 10.16 (0.400) 0.38 (0.015) 4.57 (0.180)
