UCN5833

5833 UCN5833EP SERIAL DATA OUT POWER GROUND OUTPUT ENABLE SERIAL DATA IN BiMOS II 32-BIT SERIAL-INPUT, LATCHED DRIVER Designed to reduce logic supply current, chip size, and system cost, the UCN5833A/EP integrated circuits offer high-speed operation for thermal printers. These devices can also be used to drive multiplexed LED displays or incandescent lamps within their 125 mA peak output current rating. The combination of bipolar and MOS technologies gives BiMOS II smart power ICs an interface flexibility beyond the reach of standard buffers and power driver circuits. 39 38 37 36 Data Sheet 26185.16A* STROBE LOGIC SUPPLY CLOCK OUT32 41 OUT1 NC CLK 44 43 OE 42 VDD 1 ST 4 40 5 6 3 2 NC OUT 2 OUT 3 OUT 4 OUT 5 OUT 6 OUT 7 OUT 8 OUT 9 OUT10 OUT11 OUT 12 7 8 9 10 OUT31 OUT30 OUT29 OUT28 OUT27 OUT26 OUT25 OUT24 OUT23 OUT22 OUT21 11 12 13 14 15 16 17 35 34 33 32 31 30 29 These 32-bit drivers have bipolar open-collector npn Darlington outputs, a CMOS data latch for each of the drivers, a 32-bit CMOS shift register, and CMOS control circuitry. The high-speed CMOS shift registers and latches allow operation with most microprocessor-based systems at data input rates above 3.3 MHz. Use of these drivers with TTL may require input pull-up resistors to ensure an input logic high. The UCN5833A is supplied in a 40-pin dual in-line plastic package with 0.600" (15.24 mm) row spacing. At an ambient temperature of +75°C, all outputs of the DlP-packaged device will sustain ...
