NPIC6C4894D: Power logic 12-bit shift register; open-drain outputs
The NPIC6C4894 is a 12-stage serial shift register. It has a storage latch associated with
each stage for strobing data from the serial input (D) to the parallel open-drain outputs
(QP0 to QP11). Data is shifted on positive-going clock (CP) transitions. The data in each
shift register stage is transferred to the storage register when the latch enable (LE) input is
HIGH. Data in the storage register drives the gate of the output extended-drain NMOS
transistor whenever the output enable input (OE) is HIGH. A LOW on OE causes the
outputs to assume a high-impedance OFF-state. Operation of the OE input does not affect
the state of the registers. Two serial outputs (QS1 and QS2) are available for cascading a
number of NIC6C4894 devices. Serial data is available at QS1 on positive-going clock
edges to allow high-speed operation in cascaded systems with a fast clock rise time. The
same serial data is available at QS2 on the next negative going clock edge. It is used for
cascading NPIC6C4894 devices when the clock has a slow rise time. The open-drain
outputs are 33 V/100 mA continuous current extended-drain NMOS transistors designed
for use in systems that require moderate load power such as LEDs. Integrated voltage
clamps in the outputs, provide protection against inductive transients. This protection
makes the device suitable for power driver applications such as relays, solenoids and
other low-current or medium-voltage loads.
