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,
