M82C55A-2 I/O Expander IC 40-DIP

From the shop's description

M82C55A-2 I/O Expander IC 40-DIP for Efficient Digital Control The MSM82C55A-2 is a programmable universal I/O interface device which operates as high speed and on low power consumption due to 3m silicon gate CMOS technology. It is the best fit as an I/O port in a system which employs the 8-bit parallel processing MSM80C85AH CPU. This device has 24-bit I/O pins equivalent to three 8-bit I/O ports and all inputs/outputs are TTL interface compatible. Features: High speed and low power consumption due to 3m silicon gate CMOS technology 3 V to 6 V single power supply Full static operation Programmable 24-bit I/O ports Bidirectional bus operation (Port A) Bit set/reset function (Port C) TTL compatible Compatible with 8255A-5 40-pin Plastic DIP (DIP40-P-600-2.54): (Product name: MSM82C55A-2RS) Specifications: I/O port 24 bits programmable Supply voltage 3-6V Minimum operating temperature – 40°C Maximum operating temperature + 85°C Mounting type Through hole Packing style 40-DIP MSM82C55A-2RS Datasheet
