HIGH-VOLTAGE, HIGH-CURRENT
SOURCE DRIVERS
Series UDS2980H and UDS2980R hermetically sealed source
drivers link standard low-power digital logic and relays, solenoids,
magnetic print hammers, stepping motors, LEDs, and lamps in
applications requiring separate logic and load grounds, load supply
voltages to +80V, and load currents to 500 mA.
Types UDS2981H/R and UDS2983H/R are intended for use
with 5v logic systems(TTL, Schottky TTL. DTL and 5V CMOS).
UDS2982H/R and UDS2984H/R integrated circuits are intended for
MOS interface (PMOS and CMOS) operating from supply voltages
of from 6 to 16V.
Types UDS2981H/R and UDS2982H/R will withstand an output
OFF voltage of 50 V. UDS2983H/R and UDS2984H/R drivers will
withstand a maximum output OFF voltage of 80V.
Under normal operating conditions, the devices will sustain 50
mA continuously on each of the eight outputs at an ambient
temperature of +85°c and with a supply voltage of 15V. All types
include input current-limiting resistors and output transient-
suppression diodes. In all cases, outputs are swiched ON by an
active high input level.
Note that the maximum current rating may not be obtained at -
55°c because of reduced beta, or at +125°c because of package
power limitations.
Series UDS2980H drivers are furnished in 18-pin
ceramic/metal(side-brazed) hermetic dual in-line packages. Series
UDS2980R drivers are supplied in ceramic/glass(cer-DIP) hermetic
packages. Both are processed to the requirements of MIL-STD-883.
Class B.
The same circuits are also available in 18-pin plastic dual in-line
packages (Series UDN2980A) for operation over a limited
temperature range, or where higher package power dissipation is
needes.
