ADDENDUM
DIFFERENCES BETWEEN THE IDT72V261LA/72V271LA AND IDT72V261L/72V271L
IDT has improved the performance of the IDT72V261/72V271 SuperSync FIFOs. The new versions are designated by the “LA” mark. The LA
part is pin-for-pin compatible with the original “L” version. Some difference exist between the two versions. The following table details these differences.

1 = 10*Tf

a fixed value, independent of the
frequency of RCLK or WCLK.

a fixed value, independent of the
frequency of RCLK or WCLK.

60ns(2) + tREF + 1 TRCLK(4)
tRTF
1 = 14*Tf

NOTES:
1. WCLK and RCLK can vary independently and can be stopped. There is no restriction on operating WCLK and RCLK.
2. This is tSKEW3.
3. Tf is the period of the ‘selected clock’.
4. TRCLK is the cycle period of the read clock.
5. Typical ICC1 is based on VCC = 3.3V, tA = 25
°C, fS = WCLK frequency = RCLK frequency (in MHz using TTL levels), data switching at fS/2, CL = Capacitive Load (in pF).
