M54610P

8-BIT PARALLEL DATA INTERFACE FOR PRINTER

DESCRIPTION

The M54610P is a semiconductor integrated circuit consisting of an

8-bit parallel data interface function.

FEATURES

q I/O electrical characteristics equivalent to LSTTL

q 3-state 8-bit data output

q Strobe signal with polarity switching input

q Wide operating temperature range Ta = -20 – +75°C

APPLICATION

Printer

FUNCTION

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.
