M48Z35, M48Z35Y

Table 8. WRITE Mode AC Characteristics

Note: 1. Valid for Ambient Operating Temperature: TA = 0 to 70°C or –40 to 85°C; VCC = 4.75 to 5.5V or 4.5 to 5.5V (except where noted).

2. CL = 5pF (see Figure 7, page 6).

3. If E goes low simultaneously with W going low, the outputs remain in the high impedance state.
