MITSUBISHI 〈DIGITAL ASSP MITSUBISHI 〈DIGITAL ASSP 〉 〉 M66007P/FP M66007P/FP 12-BIT INPUT EXPANDER 12-BIT INPUT EXPANDER DESCRIPTION The M66007 is a semiconductor integrated circuit providing the 12-bit parallel input-serial output shift register function. This product is completely designed with CMOS to sharply reduce power consumption compared with bipolar or BiCMOS product. The M66007, developed as an input only expander IC necessary for microcomputer periphery, is widely applicable as a data parallel/serial conversion IC. FEATURES Control signals of only two pins including LE/D and CLK Low power consumption of 50 µW/package maximum (Vcc=5V, Ta=25°C at time of standstill) Schmitt triggered input (LE/D, CLK, D0 to D11) Wide operating supply voltage range (Vcc=2~6V) Wide operating temperature range (Ta=–20~75°C) APPLICATION Parallel/serial data conversion for microcomputer periphery FUNCTION The M66007 uses a silicon gate CMOS process to achieve low power consumption and high noise margin. For control signals, this IC adopts only the two pins of latch input/serial data output LE/D and clock input CLK. Each bit of shift register of 12-bit parallel input-serial output consists of flip-flop for shift. When LE/D is placed in input mode, CLK is set to “H” and LE/ D changes from “H” to “L”, the status of parallel data inputs D0 to D11 at that time is latched with the flip-flop for shift and LE/ D is switched to output mode to output “L”.
