Caution: CMOS devices have input-static protection,
but are susceptible to damage when exposed to
extremely high static-electrical charges.
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 sufx ELW). These devices are lead (Pb) free, with 100%
matte tin plated leadframes.
