A6841

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 sup-

ply is up to –20 V.

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 appli-

cations 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 sufﬁ x ELW). These devices are lead (Pb) free, with 100%

matte tin plated leadframes.
