Pin Capacitance (f = 1 MHz T = 25°C) (1) Typ Max Units Conditions CIN 410 pF VIN = 0V COUT 812 pF VOUT = 0V Note: 1. Typical values for nominal supply voltage. This parameter is only sampled and is not 100% tested. AC Waveforms for Read Operation (1) Notes: 1. Timing measurement reference level is 1.5V for -45 and -55 devices. Input AC drive levels are VIL = 0.0V and VIH = 3.0V. Timing measurement reference levels for all other speed grades are VOL = 0.8V and VOH = 2.0V. Input AC drive levels are VIL = 0.45V and VIH = 2.4V. 2. OE may be delayed up to tCE - tOE after the falling edge of CE without impact on tCE . 3. OE may be delayed up to tACC - tOE after the address is valid without impact on tACC . 4. This parameter is only sampled and is not 100% tested. 5. Output float is defined as the point when data is no longer driven. Input Test Waveforms and Measurement Levels tR, tF < 5 ns (10% to 90%) For -45, -55, and -70 Devices Only: Output Test Load Note: CL = 100 pF including jig capacitance except -45, -55 and -70 devices, where CL = 30 pF. tR, tF < 20 ns (10% to 90%) For -85 and -10 Devices Only: AT27C516 3-149 |
