TB62785NG,TB62785FTG TOSHIBA Bi-CMOS INTEGRATED CIRCUIT SILICON MONOLITHIC TB62785NG, TB62785FTG 7-SEGMENT DRIVERS WITH BUILT-IN DECODERS (COMMON ANODE CAPABILITY, MAXIMUM 4-DIGIT CONTROL) TB62785NG The TB62785NG / TB62785FTG are multifunctional, compact, 7-egment LED display drivers. These ICs can directly drive 7-segment displays and individual LEDs, and can control either a 4-digit display with decimal points, or 32 individual LEDs. These ICs can also be used with common-anode displays. Their outputs are constant current, the ampere levels at which are set using an external resistor. A synchronous serial port connects the IC to the CPU. SDIP24-P-300-1.78 The different modes of control provided by this device including Weight 1.22g (typ.) Duty Control Register Set, Digit Set, Decode Set and Standby Set, are all based on every 16-bit of serial data. TB62785FTG FEATURES Control circuit power supply : VDD = 4.5 to 5.5 V Digit output rating : 17 V / -400 mA Decoder output rating : 17 V / 50 mA Built-in decoder P-VQFN24-0404-0.50-001 : Decodes the numerals 0 to 9, certain alphabetic Weight 0.037g (typ.) characters, and of course blanks code. Digit control function : Can scan digit outputs DIG-0 to DIG-3 when connected to the common anode pins of a 7-segment display. Maximum transmission frequency : fCLK = 15 MHz Decoder outputs (OUT-a to OUT-Dp) Output current can be set up to a 40mA maximum using an external resistor. Constant current tolerance (Ta = 25C, VDD = 5.0 V) : Variation between bits = 7%, variation between devices (including variation between bits) = 15% at VCE 0.7 V Package : TB62785NG SDIP24-P-300-1.78 : TB62785FTG P-VQFN24-0404-0.50-001 1 2015-01-07 TB62785NG,TB62785FTG PIN ASSIGNMENT (Top view) < TB62785NG (SDIP24) > V 1 24 L-GND DD DATA-IN 2 23 DATA-OUT CLOCK 3 22 R-EXT LOAD 4 21 P-GND OUT-f 5 20 DIG-3 OUT-g 6 19 DIG-2 TOP VIEW OUT-e 7 18 V CC OUT-d 8 17 DIG-1 OUT-Dp 9 16 DIG-0 OUT-c 10 15 TEST-IN1 OUT-b 11 14 TEST-IN2 OUT-a 12 13 P-GND < TB62785FTG (VQFN24) > R-EXT 19 12 TEST-IN1 DATA-OUT 20 11 TEST-IN2 (Note) L-GND 21 10 P-GND TOP VIEW 22 9 OUT-a (Note) V DD DATA-IN 23 8 OUT-b CLOCK 24 7 OUT-c *Note: VDD and L-GND are adjacent in TB62785FTG.
