8-BIT SERIAL-INPUT, CONSTANT-

CURRENT LATCHED LED DRIVER

PRELIMINARY INFORMATION

(Subject to change without notice)

July 20, 2000

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%

selected current with the application of a logic high.

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).

Dwg. PP-029-17A

Note that the A6277EA (DIP) and the A6277ELW

(SOIC) are electrically identical and share a

common terminal number assignment.

tible to damage if exposed to extremely high

static electrical charges.

Always order by complete part number, e.g., A6277EA .
