DH0028C/DH0028CN*hammer driver
general description
The DH0028C/DH0028CN is a high current
hammer driver designed for utilization in a wide
variety of printer applications. The device is
capable of driving 6 amp pulsed loads at duty
cycles up to 10% (1 ms ON/10 ms OFF). The
input is DTL/TTL compatible and requires only a
single voltage supply in the range of 10V to 45V.
