Description
The merging of low-power CMOS logic and bipolar output power drivers permit the UCN5841A, UCN5841LW, and A5841SLW integrated circuits to be used in a wide variety of peripheral power driver applications. 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. All drivers can be operated with a split supply where the negative supply is up to -20 V.
BiMOS II devices 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.
