input, latched source drivers are designed for applications emphasizing
low output saturation voltages and currents to -250 mA per output.
These smart high-side octal, driver ICs merge an 8-bit CMOS shift
register, associated CMOS latches, and CMOS control logic (strobe
and output enable) with medium current emitter-follower (sourcing)
outputs. Typical applications include incandescent or LED displays
(both directly driven and multiplexed), non-impact (i.e., thermal)
printers, relays, and solenoids.
channel. The maximum supply voltage is 50 V and a minimum output
sustaining voltage rating of 35 V for inductive load applications. Under
normal operating conditions, the UCN5895A and UCN5895EP are
capable of providing -120 mA (8 outputs continuous and simultaneous)
at +65 C with a logic supply of 5 V. Similar devices, with higher output
current ratings, are the UCN5890A and UCN5891A.
With a 5 V supply, they will typically operate at better than 5 MHz.
At 12 V, significantly higher speeds are obtained.
with standard CMOS, PMOS, and NMOS circuits. TTL or DTL circuits
may require the use of appropriate pull-up resistors to ensure a proper
input-logic high. A CMOS serial data output allows cascading these
devices in multiple drive-line applications required by many dot matrix,
alphanumeric, and bar graph displays.
perature range of -20 C to +85 C. Because of limitations on package
power dissipation, the simultaneous operation of all output drivers may
require a reduction in duty cycle. The UCN5895A is supplied in a
standard 16-pin dual in-line plastic package with a copper lead frame
for increased allowable package power dissipation. The UCN5895EP
is supplied in a 20-lead plastic leaded chip carrier for minimum area,
surface-mount applications. The A5895SLW is supplied in a 16-lead
wide-body plastic SOIC.
