5 AC Read Characteristics

Table 5-2. AC Read Characteristics
Parameter	Symbol	AT28C010‑12		AT28C010‑15		AT28C010‑20		AT28C010‑25		Units
Parameter	Symbol	Min.	Max.	Min.	Max.	Min.	Max.	Min.	Max.	Units
Address to Output Delay	t_ACC	—	120	—	150	—	200	—	250	ns
CE to Output Delay	t_CE⁽¹⁾	—	120	—	150	—	200	—	250	ns
OE to Output Delay	t_OE⁽²⁾	0	50	0	55	0	55	0	55	ns
CE or OE to Output Float	t_DF^(3,4)	0	50	0	55	0	55	0	55	ns
Output Hold from OE, CE or Address, whichever occurred first	t_OH	0		0		0		0		ns
CE Pulse High Time	t_CEPH⁽⁵⁾	50	—	50	—	50	—	50	—	ns

Note:

CE may be delayed up to t_ACC‑t_CE after the address transition without impact on t_ACC.
OE may be delayed up to t_CE‑t_OE after the falling edge of CE without impact on t_CE or by t_ACC‑t_OE after an address change without impact in t_ACC.
t_DF is specified from OE or CE, whichever occurs first (C_L = 5 pF).
This parameter is characterized and is not 100% tested.
If CE is de-asserted, it must remain de-asserted for at least 50 ns during read operations, otherwise incorrect data may be read.
