LS3718

UNISONIC TECHNOLOGIES CO., LTD 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.  FEATURES * 20-Bit serial in parallel out * Cascade connection * Operating voltage 5V±10% * Hysteresis input 0.5V typ * Output current 25mA * Operating frequency 5MHz or more  ORDERING INFORMATION Ordering Number LS3718G-S28-R Package SOP-28 CMOS IC Packing Tape Reel  MARKING www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd 1 of 8 QW-R121-015.B LS3718  PIN CONFIGURATION P9 1 P10 2 P11 3 P12 4 P13 5 P14 6 VSS 7 P15 8 P16 9 P17 10 P18 11 P19 12 P20 13 SO 14 28 VDD 27 P8 26 P7 25 P6 24 P5 23 P4 22 P3 21 VSS 20 P2 19 P1 18 CLR 17 STB...
