8-BIT PARALLEL DATA INTERFACE FOR PRINTER M 54610P MITSUBISHI <CONTROL / DRIVER IC> PIN C O N FIG URAT IO N TO P VIEW DES CRIPT IO N The M54610P is a semiconductor integrated circuit consisting of an 8-bit parallel data interface function. FEAT URES l I/O electrical characteristics equivalent to LSTTL l 3-state 8-bit data output l Strobe signal with polarity switching input l Wide operating temperature range Ta = -20 – +75 C APP LICAT IO N Printer FUNCT IO N The M54610P, when used in a printer, is capable of implementing a standard 8-bit parallel data interface. As shown in the timing diagram, printing data DIN 1 through 8 and strobe pulses STB are input from a host computer. Data are exchanged by outputing the BUSY and ACK (ACKNOWLEDGE) signals to the host computer. Control signals EBSY, CS, WR, RD and ACKI are input from a printer controller, and this IC outputs DOU 1 through 8, and BSYF.
