8-BIT SERIAL-INPUT, CONSTANT-
CURRENT LATCHED LED DRIVER
Always order by complete part number, e.g.,
A6275EA
.
The A6275EA and A6275ELW are specifically designed for LED-
display applications. Each BiCMOS device includes an 8-bit CMOS
shift register, accompanying data latches, and eight npn constant-
current sink drivers. Except for package style and allowable package
power dissipation, the two devices are identical.
The CMOS shift register and latches allow direct interfacing with
microprocessor-based systems. With a 5 V logic supply, typical serial
data-input rates are up to 20 MHz. The LED drive current is deter-
mined by the user’s selection of a single resistor. A CMOS serial data
output permits cascade connections in applications requiring additional
drive lines. For inter-digit blanking, all output drivers can be disabled
with an ENABLE input high. Similar 16-bit devices are available as
the A6276EA and A6276ELW.
Two package styles are provided for through-hole DIP (suffix A) or
surface-mount SOIC (suffix LW). Under normal applications, copper
lead frames and low logic-power dissipation allow these devices to
sink maximum rated current through all outputs continuously over the
operating temperature range (90 mA, 0.9 V drop, +85
°
C). Both
devices are also available for operation over the standard temperature
range of -20
°
C to +85
°
C. To order, change the suffix letter ‘E’ to ‘S’.
