Caution: These CMOS devices have input static

protection (Class 3) but are still susceptible to damage if

exposed to extremely high static electrical charges.

Note that the A6B273KA (DIP) and the A6B273KLW

(SOIC) are electrically identical and share a common

terminal number assignment.

triggered D-type) data latches and DMOS outputs for systems requiring

relatively high load power. Driver applications include relays, sole-

noids, and other medium-current or high-voltage peripheral power

loads. The CMOS inputs and latches allow direct interfacing with

microprocessor-based systems. Use with TTL may require appropriate

pull-up resistors to ensure an input logic high.

drivers are disabled (the DMOS sink drivers turned OFF) with the

CLEAR input low. The A6B273KA/KLW DMOS open-drain outputs

are capable of sinking up to 500 mA. Similar devices with reduced

package. The A6B273KLW is furnished in a 20-lead wide-body,

small-outline plastic package (SOIC) with gull-wing leads for surface-

mount applications. Copper lead frames, reduced supply current

requirements, and low on-state resistance allow both devices to sink

150 mA from all outputs continuously, to ambient temperatures over

85 C.
