8-BIT SERIAL-INPUT, CONSTANT-

CURRENT LATCHED LED DRIVER

The A6277x is specifically designed for LED-display applications.

Each BiCMOS device includes an 8-bit CMOS shift register, accompa-

nying data latches, and eight npn constant-current sink drivers. Two

package styles and two operating temperature ranges are available.

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. In addition, a HIGH/LOW function

enables full selected current with the application of a logic low, or 50%

The first character of the part number suffix determines the device

operating temperature range. Suffix ‘E–’ is for -40°C to +85°C, and

suffix ‘S–’ is -20°C to +85°C. Two package styles are provided for

through-hole DIP (suffix ‘–A’) or surface-mount SOIC (suffix ‘–LW’)

applications. The copper lead frame and low logic-power dissipation

allow the dual in-line package to sink 122 mA through all outputs

continuously over the operating temperature range (1.0 V drop,

+85°C).

Note that the A6277EA (DIP) and the A6277ELW

(SOIC) are electrically identical and share a

common terminal number assignment.

*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: A6277EA, A6277ELW,

A6277ELWTR, A6277SA, A6277SLW, and A6277SLWTR.

T_S........................... -55°C to +150°C

Caution: These CMOS devices have input

static protection (Class 2) but are still suscep-

tible to damage if exposed to extremely high

static electrical charges.
