DABiC-5 8-Bit Serial Input Latched Sink Drivers
The merging of low-power CMOS logic and bipolar output power drivers permit the A6841 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 package variations of the A6841 offer premium performance with a minimum output-breakdown voltage rating of 50 V (35 V sustaining). All drivers can be operated with a split supply where the negative supply is up to –20 V. Package LW 18-pin Wide Body SOIC The CMOS inputs are compatible with standard CMOS 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 A6841SA devices are furnished in a standard 18-pin plastic DIP. The A6841SLW device is available in an 18-lead SOIC package. A 20-pin SOIC version, A6841SLW-20 has improved thermal characteristics. The SOIC drivers are also available for operation to a temperature of –40°C (part number suffix ELW). These devices are lead (Pb) free, with 100% matte tin plated leadframes.
