AC Read Characteristics

Table 1. AC Read Characteristics
Parameter Symbol AT28C010‑12 AT28C010‑15 AT28C010‑20 AT28C010‑25 Units
Min. Max. Min. Max. Min. Max. Min. Max.
Address to Output Delay tACC 120 150 200 250 ns
CE to Output Delay tCE(1) 120 150 200 250 ns
OE to Output Delay tOE(2) 0 50 0 55 0 55 0 55 ns
CE or OE to Output Float tDF(3,4) 0 50 0 55 0 55 0 55 ns

Output Hold from OE, CE or Address, whichever occurred first

tOH 0   0   0   0   ns
CE Pulse High Time tCEPH(5) 50 50 50 50 ns
Notes:
  1. 1.CE may be delayed up to tACC‑tCE after the address transition without impact on tACC.
  2. 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 in tACC.
  3. 3.tDF is specified from OE or CE, whichever occurs first (CL = 5 pF).
  4. 4.This parameter is characterized and is not 100% tested.
  5. 5.If CE is de-asserted, it must remain de-asserted for at least 50 ns during read operations, otherwise incorrect data may be read.
