28-LINE DECODER/DRIVER
Intended for use in ink-jet printer applications, the A5817SEP
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

R _{Caution: CMOS devices have input static}
(OUT_An and/or OUT_Bn). Special internal circuitry is programmed at the
time of manufacture to adjust the output pulse timing and thereby the
energy the device delivers to the ink-jet print head.
The CMOS inputs cause minimal loading and are compatible with
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.
The A5817SEP is furnished in a 44-lead plastic chip carrier
(quad pack) for minimum-area, surface-mount applications.
