M48T212Y, M48T212V
12/32
Table 6. WRITE Mode AC Characteristics
Note: 1. Valid for Ambient Operating Temperature: TA = 0 to 70°C or –40 to 85°C; VCC = 4.5 to 5.5V or 3.0 to 3.6V (except where noted).
2. CL = 5pF
3. If E goes low simultaneously with W going low, the outputs remain in the high impedance state.
