9 / 32 page ![]() Obsolete Product(s) - Obsolete Product(s) Obsolete Product(s) - Obsolete Product(s) M48T59, M48T59Y, M48T59V Operation modes 9/32 The state of the eight three-state Data I/O signals is controlled by E and G. If the outputs are activated before tAVQV, the data lines will be driven to an indeterminate state until tAVQV. If the Address Inputs are changed while E and G remain active, output data will remain valid for Output Data Hold time (tAXQX) but will go indeterminate until the next Address Access. Figure 5. Read mode AC waveforms Note: WRITE enable (W) = High. Table 3. Read mode AC characteristics Symbol Parameter(1) 1. Valid for ambient operating temperature: TA = 0 to 70°C; VCC = 4.5 to 5.5 V, 4.75 to 5.5 V, or 3.0 to 3.6 V (except where noted). M48T59/Y/V Unit –70 Min Max tAVAV READ cycle time 70 ns tAVQV (2) 2.
