UCN5833
BiMOS II 32-Bit Serial-Input Latched Drivers

The 5833 has been phased out of production as of October 31, 2005.

For samples and information on the replacement part, please refer to the A6833.

Features

• To 3.3 MHz Data Input Rate
• 30 V Minimum Output Breakdown
• Darlington Current-Sink Outputs
• Low-Power CMOS Logic and Latches

Description

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.

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.
