IDT70P258/248L

Low Power 1.8V 8K/4K x 16 Dual-Port Static RAM

Industrial Temperature Range

5

Capacitance

(TA = +25°C, f = 1.0MHz)

NOTES:

1.

This parameter is determined by device characterization but is not production

tested.

2.

3dV references the interpolated capacitance when the input and output signals

switch from 0V to 3V or from 3V to 0V.
