description
The TPIC6B595 is a monolithic, high-voltage,
medium-current power 8-bit shift register
designed for use in systems that require relatively
high load power. The device contains a built-in
voltage clamp on the outputs for inductive
transient protection. Power driver applications
include relays, solenoids, and other mediumcurrent
or high-voltage loads.
This device contains an 8-bit serial-in, parallel-out
shift register that feeds an 8-bit D-type storage
register. Data transfers through both the shift and
storage registers on the rising edge of the
shift-register clock (SRCK) and the register clock
(RCK), respectively. The storage register
transfers data to the output buffer when shiftregister
clear (SRCLR) is high. When SRCLR is
low, the input shift register is cleared. When output
enable (G) is held high, all data in the output
buffers is held low and all drain outputs are off.
When G is held low, data from the storage register
is transparent to the output buffers. When data in
the output buffers is low, the DMOS-transistor
outputs are off. When data is high, the DMOStransistor
outputs have sink-current capability.
The serial output (SER OUT) allows for cascading
of the data from the shift register to additional
devices.
