between low-level logic and peripheral power devices such as sole-

noids, motors, incandescent displays, heaters, and similar loads of up to

320 W per channel. Both integrated circuits include transient-suppres-

sion diodes that enable use with inductive loads. The input logic is

compatible with most TTL, DTL, LSTTL, and 5 V CMOS logic.

for output-voltage ratings. The former is rated for operation to 50 V

(35 V sustaining), while the latter has a minimum output breakdown

rating of 80 V (50 V sustaining). The lower-cost UDN2879W-2 is

recommended for applications requiring load currents of 3 A or less.

These less expensive devices are identical to the basic parts except for

the maximum allowable load-current rating.

in a 12-pin single in-line power-tab package. The tab needs no insula-

tion. External heat sinks are usually required for proper operation of

these devices.
