Input/Output CMOS Generic Characteristics

The values presented in the following table apply for all CMOS inputs and/ or outputs unless specified oth-

erwise.

Table 12. CMOS IO buffers generic characteristics

The reference current is dependent on the exact buffer chosen and is a part of the buffer name. The avail-

able values are 2, 4 and 8 mA.

Input/Output TTL Generic Characteristics

The values presented in the following table apply for all TTL inputs and/or outputs unless specified other-

wise.

Table 13. TTL IO buffers generic characteristics

The reference current is dependent on the exact buffer chosen and is a part of the buffer name. The avail-

able values are currently 2, 4 and 8 mA.
