Data Sheet 26185.16A* 5833 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.

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 50 mA continuously. For high-density applications, the UCN5833EP is available. This 44-lead plastic chip carrier (quad pack) is intended for surface-mounting on solder lands with 0.050" (1.27 mm) centers. CMOS serial data outputs permit cascading for applications requiring additional drive lines. Dwg.

Typical Time Between Strobe Activation and Output Transition ........................................................................... 500 ns Serial Data present at the input is transferred to the shift register on the logic “0” to logic “1” transition of the CLOCK input pulse. On succeeding CLOCK pulses, the registers shift data information towards the SERIAL DATA OUTPUT. The SERIAL DATA must appear at the input prior to the rising edge of the CLOCK input waveform. Information present at any register is transferred to its respective latch when the STROBE is high (serial-to-parallel conversion). The latches will continue to accept new data as long as the STROBE is held high. Applications where the latches are bypassed (STROBE tied high) will require that the OUTPUT ENABLE input be low during serial data entry. When the OUTPUT ENABLE input is low, all of the output buffers are disabled (OFF) without affecting the information stored in the latches or shift register. With the OUTPUT ENABLE input high, the outputs are controlled by the state of the latches. 115 Northeast Cutoff, Box 15036 Worcester, Massachusetts 01615-0036 (508) 853-5000 5833 BiMOS II 32-BIT SERIAL-INPUT, LATCHED DRIVER UCN5833A Dimensions in Inches (controlling dimensions) 40 0.015 0.008 21 0.700 MAX 0.580 0.485 0.600 BSC 1 2 0.070 0.030 3 20 0.100 4 2.095 1.980 BSC 0.005 MIN 0.250 MAX 0.015 0.200 0.115 MIN 0.022 0.014 Dwg.
