M81049P/SP/FP
OCTAL D-TYPE FLIP-FLOP DRIVER WITH CLEAR
DESCRIPTION
M81049 is octal D-type flip-flop driver by 20-pin package. It
has 8 same circuit units which is composed of D-type flip-flop
logic circuit and high voltage NchMOS output transistor.
M81049 has a common direct clear input and a common
clock input.
FEATURES
● _{Lineup with three packages}
● _{High breakdown voltage (BVDSX ≥ 40V)}
● _{Drain output current (IDS(max) = 200mA)}
● _{With input protection diodes}
● _{Pin assignment of input-output flow through}
● _{Wide operating temperature range (Ta = –40 to +85°C)}

FUNCTION
The common direct clear input and common clock input are
connected to every circuit unit by the same way. Signal at the
D inputs is transferred to Y outputs by D-type flip-flops on the
positive-going edge of the clock pulse.
If CLR is set to “L”, outputs Y1-Y8 will be altogether set to “H”
regardless of D1-D8 and CLK.
The maximum drain current of an output is 200mA. The
maximum between drain-source is 40V.
