The UCN5821A from Allegro MicroSystems is an 8-bit serial input latched driver utilizing BiMOS II technology, a combination of bipolar and MOS processes. This integration provides enhanced interface flexibility.
The device incorporates an eight-bit CMOS shift register, CMOS control circuitry, eight CMOS data latches, and eight bipolar current-sinking Darlington output drivers. It supports a data input rate of up to 5 MHz with a 5V logic supply, with significantly higher speeds achievable at 12V. The CMOS inputs are compatible with standard CMOS, NMOS, and TTL logic levels, though TTL circuits may require pull-up resistors.
Designed for through-hole mounting in a DIP package, the UCN5821A operates within a temperature range of -20°C to 85°C. The output drivers are capable of sinking current up to 350mA. Drivers can be cascaded using the serial data output for applications requiring additional drive lines.
This part is classified as Last Time Buy, indicating it is obsolete and not recommended for new designs. Sale is restricted to existing customer applications.
