BiMOS II 8-BIT SERIAL-INPUT,
LATCHED DRIVERS
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’.
FEATURES
I To 3.3 MHz Data Input Rate
I CMOS, NMOS, TTL Compatible
I Internal Pull-Down Resistors
I Low-Power CMOS Logic & Latches
I High-Voltage Current-Sink Outputs
I Automotive Capable
