Note that the A6276EA (DIP) and the A6276ELW
(SOIC) are electrically identical and share a
common terminal number assignment.

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.
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’.
