SCF5740 Datasheet | Siemens Semiconductor Group

FEATURES DESCRIPTION The SCF574X is a four digit, dot addressable 5x7 dot matrix, serial input, alphanumeric Intelligent Display. The four digits are packaged in a rugged, high quality, optically transparent, plastic 22 pin DIP with 0.1” pin spacing. The on-board CMOS has a 140 bit RAM, one bit associated with one LED, each to generate User Defined Characters. In Power Down Mode, quiescent current is <50 µA. The SCF574X is designed for work with the serial port of most mon microprocessors. Data is transferred into the display through the Serial Data Input (DATA), clocked by the Serial Data Clock (SDCLK), and enabled by the Load Input (LOAD). The 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 munication equipment or eliminate the visual sychronization effects found in high vibration environments such as avionic equipment. 2- 200 Maximum Rating DC Supply Voltage - 0.5 to +7.0 Vdc Input Voltage Levels Relative to Ground - 0.5 to VCC+0.5 Vdc Operating Temperature - 40°C to +85°C Storage Temperature - 40°C to +100°C Maximum Solder Temperature 0.063" below Seating Plane, t<5 sec 260°C Relative Humidity at 85°C 85% Maximum Number of LEDs at 100% Brightness 64 Maximum Power Dissipation 0.65 W ESD (100 p F, 1.5 KΩ) 2 KV Maximum Input Current ± 186 m A Switching...
