GTL2003

8-bit bidirectional low voltage translator

12. Dynamic characteristics

12.1 Dynamic characteristics for translator-type application

[1]

All typical values are measured at VDD1 = 3.3 V, VDD2 = 2.5 V, Vref = 1.5 V and Tamb =25 °C.

[2]

Propagation delay is measured using Figure 9 and is a difference measurement. It is not production tested

and is guaranteed by ON-state resistance.

[3]

Cio(on) maximum of 30 pF and Cio(off) maximum of 15 pF is guaranteed by design.

Table 10.

Dynamic characteristics

Tamb = −40 °C to +85 °C; Vref = 1.365 V to 1.635 V; VDD1 = 3.0 V to 3.6 V; VDD2 = 2.36 V to 2.64 V;

GND = 0 V; tr =tf ≤ 3.0 ns; unless otherwise speciﬁed. Refer to Figure 9.
