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
