详细描述

UCN5821A - BiMOS II 8-BIT SERIAL-INPUT, LATCHED DRIVERS - Allegro MicroSystems

A merged combination of bipolar and MOS technology gives

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.

BiMOS II devices have much higher data-input rates than the

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.

The UCN5821/22A are furnished in a standard 16-pin plastic

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’.
