LS3718
20-BIT SERIAL TO PARALLEL
CONVERTER
DESCRIPTION
The UTC LS3718 is a 20-bit serial to parallel converter utilizing
CMOS Technology. It is incorporates control circuit, shift register,
latch and driver into a single ship. It is suitable for MCU interface.
The effective interface assignment of MPU is available as the
connection between UTC LS3718 and MPU is required only 4
lines.
The device is designed to operate up to 5MHz. When the serial
data input to the DATA terminal and the data is output from parallel
output buffer through serial in parallel out shift register and parallel
data latches.
The data can through the shift register serial output to the SO
terminal. Therefore the UTC LS3718 can cascade connection to
expand the output data number.
The hysteresis input circuit realizes wide noise margin and the
high drive-ability output buffer (25mA) can drive LED directly.
