Slow memory mode timing. 10. Fast memory or DMA mode of operation, except the first conversion which is equal to tCONV. 11. Maximum specification to prevent multiple triggering with WR. 12. All input drive signals are specified with tr = tf ≤ 20ns and shall swing from VIL -0.4V to VIH +0.4V for all timing specifications. A signal is considered to change state as it crosses a 1.4V threshold (except tRD and tRX). 13. tr and tf load is CL = 100pF (including stray capacitance) to DG and is measured from the 10 - 90% point. 14. tRD is the time required for the data output level to change by 10% in response to RD crossing a voltage level of 1.4V. High-Z to VOH is measured with RL = 2.5kΩ and CL = 100pF (including stray) to DG. High-Z to VOL is measured with RL = 2.5kΩ to V+ and CL = 100pF (including stray) to DG. 15. tRX is the time required for the data output level to change by 10% in response to RD crossing a voltage level of 1.4V. VOH to High-Z is measured with RL = 2.5kΩ and CL = 10pF (including stray) to DG. VOL to High-Z is measured with RL = 2.5kΩ to V+ and CL = 10pF (including stray) to DG. HI-7152 |
