NJU3718 Ver.2003-11-18 20-BIT SERIAL TO PARALLEL CONVERTER GENERAL DESCRIPTION The NJU3718 is a 20-bit serial to parallel converter especially applying to MPU outport expander. The effective outport assignment of MPU is available as the connection between NJU3718 and MPU using only 4 lines. The serial data synchronizing with 5MHz or more clock can be input to the serial data input terminal and the data are output from parallel output buffer through serial in parallel out shift register and parallel data latches. Furthermore, the NJU3718 outputs the serial data from SO terminal through the shift register. Therefore, it connects with other SIPO ICs like as NJU3711 in cascade for expanding the parallel conversion outputs. The hysteresis input circuit realizes wide noise margin and the high drive-ability output buffer (25mA) can drive LED directly.

NJU3555 718 - 3 - Ver.2003-11-18 FUNCTIONAL DESCRIPTION (1) Reset When the "L" level is input to the CLR terminal, all latches are reset and all of parallel conversion output are "L" level. Normally, the CLR terminal should be "H" level. (2) Data Transmission In the STB terminal is "H" level and the clock signals are inputted to the CLK terminal, the serial data into the DATA terminal are shifted in the shift register synchronizing at a rising edge of the clock signal. When the STB terminal is changed to "L" level, the data in the shift register are transferred to the latches. Even if the STB terminal is "L" level, the input clock signal shifts the data in the shift register, therefore, the clock signal should be controlled for data order. (3) Cascade Connection The serial data input from DATA terminal is output from the SO terminal through internal shift register unrelated with the CLR and STB status. Furthermore, the 4 input circuits provide a hysteresis characteristics using the schmitt trigger structure to protect the noise. CLK STB CLR OPERATION X X L All of latches are reset (the data in the shift register is no change). All of parallel conversion outputs are "L". H H The serial data into the DATA terminal are inputted to the shift register. In this stage, the data in the latch is not changed. L H The data in the shift register is transferred to the latch. And the data in the latch is output from the parallel conversion output terminals. L H When the clock signal is inputted into the CLK terminal in state of the STB="L" and CLR="H", the data is shifted in the shift register and latched data is also changed in accordance with the shift register. Note 1) X: Don’t care
