READ CYCLES 1 AND 2 (See Notes 1 and 2) MCM6709BR–6 MCM6709BR–7 MCM6709BR–8 Parameter Symbol Min Max Min Max Min Max Unit Notes Read Cycle Time tAVAV 6 — 7 — 8 — ns 3 Address Access Time tAVQV — 6 — 7 — 8 ns Chip Enable Access Time tELQV — 6 — 7 — 8 ns Output Enable Access Time tGLQV — 4 — 4 — 4 ns Output Hold from Address Change tAXQX 3 — 3 — 3 — ns Chip Enable Low to Output Active tELQX 3 — 3 — 3 — ns 4, 5, 6 Output Enable Low to Output Active tGLQX 0 — 0 — 0 — ns 4, 5, 6 Chip Enable High to Output High–Z tEHQZ — 3 — 3.5 — 3.5 ns 4, 5, 6 Output Enable High to Output High–Z tGHQZ — 3 — 3.5 — 3.5 ns 4, 5, 6 NOTES: 1. W is high for read cycle. 2. Product sensitivities to noise require proper grounding and decoupling of power supplies as well as minimization or elimination of bus contention conditions during read and write cycles. 3. All read cycle timings are referenced from the last valid address to the first transitioning address. 4. At any given voltage and temperature, tEHQZ max is less than tELQX min, and tGHQZ max is less than tGLQX min, both for a given device and from device to device. 5. Transition is measured 200 mV from steady–state voltage with load of Figure 1b. 6. This parameter is sampled and not 100% tested. OUTPUT Z0 = 50 Ω RL = 50 Ω VL = 1.5 V (a) (b) 5 pF +5 V OUTPUT 255 Ω 480 Ω The table of timing values shows either a minimum or a maximum limit for each param- eter. Input requirements are specified from the external system point of view. Thus, ad- dress setup time is shown as a minimum since the system must supply at least that much time. On the other hand, responses from the memory are specified from the de- vice point of view. Thus, the access time is shown as a maximum since the device never provides data later than that time.
