by UDN2596A and UDN2597A sink driver ICs. These devices can be
used as interface buffers between standard low-power digital logic
(particularly MOS) and high-power loads such as relays, solenoids,
stepping motors, and LED or incandescent displays. The eight satu-
rated sink drivers in each device feature high-voltage, high-current
open-collector outputs. Transient suppression clamp diodes and a
minimum 35 V output sustaining voltage allow their use with many
inductive loads.
emitter voltage drops as well as improved turn-off times due to an
active pull-down function within the output predrive section. The
UDN2596A is for use with output loads to 500 mA while the
UDN2597A is for use with loads to 1 A. Adjacent outputs may be
paralleled for higher load currents.
logic level consistent with the much greater sinking capability associ-
ated with NMOS, CMOS, and TTL logic. The UDN2596A and
UDN2597A are rated for use with 5 V logic levels.
leadframes for improved thermal characteristics. The UDN2596A is
also available for operation between -40 C and +85 C. To order,
change the prefix from ‘UDN’ to ‘UDQ’.
