6 / 12 page ![]() AT49F080/080T 6 AC Read Waveforms Notes: 1. CE may be delayed up to tACC - tCE after the address transition without impact on tACC. 2. OE may be delayed up to tCE - tOE after the falling edge of CE without impact on tCE or by tACC - tOE after an address change without impact on tACC. 3. tDF is specified from OE or CE whichever occurs first (CL = 5 pF). 4. This parameter is characterized and is not 100% tested AC Read Characteristics Symbol Parameter AT49F080-90 AT49F080-12 AT49F080-15 Units MinMax MinMax Min Max tACC Address to Output Delay 90 120 150 ns tCE (1) CE to Output Delay 90 120 150 ns tOE (2) OE to Output Delay 0 40 0 50 0 70 ns tDF (3)(4) CE or OE to Output Float 0 25 0 30 0 40 ns tOH Output Hold from OE, CE or Address, whichever occurred first 00 0 ns ADDRESS OUTPUT HIGH Z OUTPUT OE CE tACC tOE tDF tOH tCE VALID ADDRESS VALID Input Test Waveforms and Measurement level tR, tF < 5 ns AC MEASUREMENT LEVEL AC DRIVING LEVELS 0.0V 3.0V 1.5V Output Test Load OUTPUT PIN 5.0V 100 pF 1.8K 1.3K Note: 1.
