16-BIT SERIAL-INPUT, CONSTANT-

CURRENT LATCHED LED DRIVER

The A6276EA and A6276ELW are specifically designed for LED-

display applications. Each BiCMOS device includes a 16-bit CMOS

shift register, accompanying data latches, and 16 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 8-bit devices are available as the

A6275EA and A6275ELW.

Two package styles are provided for through-hole DIP (suffix A) or

surface-mount SOIC (suffix LW). Under normal applications, a copper

lead frame and low logic-power dissipation allow the dual in-line

package to sink maximum rated current through all outputs continu-

ously over the operating temperature range (90 mA, 0.75 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’.

Note that the A6276EA (DIP) and the A6276ELW

(SOIC) are electrically identical and share a

common terminal number assignment.
