Caution: These CMOS devices have input static
protection (Class 2) but are still sus cep ti ble
to damage if exposed to extremely high static
electrical charges.
Note that the A6275EA (DIP) and the A6275ELW
(SOIC) are electrically identical and share a common
terminal number assignment.

shift register, accompanying data latches, and eight npn constant-cur-
rent sink drivers. Except for package style and allowable package
power dissipation, the two devices are identical.
microprocessor-based systems. With a 5 V logic supply, typical serial
data-input rates are up to 20 MHz. The LED drive current is de ter -
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 150 mA output devices are avail-
able as the A6277EA and A6277ELW; similar 16-bit devices
are available as the A6276EA and A6276ELW.
surface-mount SOIC (suffi x 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 oper-
ating temperature range (90 mA, 0.9 V drop, +85°C).
FEATURES
■ To 90 mA Constant-Current Outputs
■ Under-Voltage Lockout
■ Low-Power CMOS Logic and Latches
■ High Data Input Rate
■ Pin-Compatible with TB62705CP
*Pb-based variants are being phased out of the product line. The variants cited in this
footnote are in production but have been determined to be NOT FOR NEW DESIGN.
This classification indicates that sale of this device is currently restricted to existing
customer applications. The variants should not be purchased for new design applica-
tions because obsolescence in the near future is probable. Samples are no longer
available. Status change: May 1, 2006. These variants include:A6275EA, A6275ELW,
