Each device has an eight-bit CMOS shift register and CMOS control circuitry, eight CMOS data latches, and eight bipolar current-sinking Darlington output drivers. The 500 mA npn Darlington outputs, with integral transient-suppression diodes, are suitable for use with relays, solenoids, and other inductive loads. Except for packaging and the maximum driver output voltage ratings, the UCN5841A, UCN5841LW, A5841SLW, UCN5842A, UCN5842LW, and A5842SLW are identical. All package variations of the 5842 offer premium performance with a minimum output-breakdown voltage rating of 80 V (50 V sustaining). All drivers can be operated with a split supply where the negative supply is up to -20 V.
BiMOS II devices UCN5841A, UCN5841LW, A5841SLW, UCN5842A, UCN5842LW, and A5842SLW have higher data-input rates than the earlier 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, drivers can be cascaded for interface applications requiring additional drive lines.
The UCN5841A, UCN5841LW, A5841SLW, UCN5842A, UCN5842LW, and A5842SLW are furnished in a standard 18-pin plastic DIP; the UCN584xLW devices are in an 18-lead surface-mountable wide-body SOIC package; the A584xSLW devices are provided in a 20- lead wide-body SOIC package with improved thermal characteristics.
The A5841SLW and UCN5841LW drivers are also available for operation to a temperature of -40°C. To order, change the suffix from SLW' to 'ELW', or change the prefix from 'UCN' to 'UCQ'.
