industrial operating temperature ranges for user flexibility of
system design. The families also support low data retention
voltage for battery back-up operation with low data retention
current.
FEATURES
Process Technology: TFT
Organization: 1M x8
Power Supply Voltage: 4.5~5.5V
Low Data Retention Voltage: 2.0V(Min)
Three state output and TTL Compatible
Package Type: 44-TSOP2-400F/R

ABSOLUTE MAXIMUM RATINGS
1)
1. Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. Functional operation should be
restricted to recommended operating condition. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
