addressable 28-line decoder/driver combines low-power CMOS inputs

and logic with 28 high-current, high-voltage bipolar outputs. A 4-to-14

line decoder determines the selected output driver (n) in each

14-driver bank. Two independent output enable inputs (active low)

then provide the final decoding to activate 1- or 2-of-28 outputs

standard CMOS, PMOS, and NMOS logic. Use with TTL or DTL

circuits may require appropriate pull-up resistors to ensure an input

logic high. The internal CMOS logic operates from a 5 V supply.

A CHIP ENABLE function is provided to lock out the drivers during

system power up. The 28 bipolar power outputs are open-collector

30 V Darlington drivers capable of sinking 500 mA at ambient

temperatures up to 85 C.
