Input/output AC characteristics

The definition and values of input/output AC characteristics are given in Figure 18 and

Table 51, respectively.

Unless otherwise specified, the parameters given are derived from tests performed under

the ambient temperature and supply voltage conditions summarized in Table 23: General

operating conditions.

1. The IIO current sourced or sunk by the device must always respect the absolute maximum rating specified inTable 20:

Voltage characteristics , and the sum of the currents sourced or sunk by all the I/Os (I/O ports and control pins) must always

respect the absolute maximum ratings ∑IIO.

2. TTL and CMOS outputs are compatible with JEDEC standards JESD36 and JESD52.

3. Specified by design – Not tested in production.
