these devices an interface flexibility beyond the reach of standard

logic buffers and power driver arrays. The UCN5821A,

UCN5821LW, UCN5822A, and UCN5822LW each have an

eight-bit CMOS shift register and CMOS control circuitry, eight

CMOS data latches, and eight bipolar current-sinking Darlington

output drivers. The UCN5821A/LW and UCN5822A/LW are

identical except for rated output voltage.

original BiMOS circuits. With a 5 V logic supply, they will

typically operate at better than 5 MHz. With a 12 V supply,

significantly higher speeds are obtained. The CMOS inputs are

compatible with standard CMOS and NMOS logic levels. TTL

circuits may require the use of appropriate pull-up resistors. By

using the serial data output, the drivers can be cascaded for

interface applications requiring additional drive lines.

DIP; the UCN5821/22LW are in a 16-lead wide-body SOIC for

surface-mount applications. The UCN5821A is also available for

operation from -40°C to +85°C. To order, change the prefix from

‘UCN’ to ‘UCQ’.
