description
The TPIC6273 is a monolithic high-voltage
high-current power logic octal D-type latch with
DMOS transistor outputs 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 medium-current or high-voltage loads.
The TPIC6273 contains eight positive-edge-
triggered D-type flip-flops with a direct clear input.
Each flip-flop features an open-drain power
DMOS transistor output.
When clear (CLR) is high, information at the D
inputs meeting the setup time requirements is
transferred to the DRAIN outputs on the positive-
going edge of the clock pulse. Clock triggering
occurs at a particular voltage level and is not
directly related to the transition time of the
positive-going pulse. When the clock input (CLK)
is at either the high or low level, the D input signal
has no effect at the output. An asynchronous CLR
is provided to turn all eight DMOS-transistor
outputs off.
The TPIC6273 is characterized for operation over
the operating case temperature range of – 40°C
to 125°C.
