4.3 Electrical Characteristics
4.3.1 DC Characteristics
All inputs and bidirectional signals have input thresholds compatible with TTL
drive levels. All outputs are CMOS drive levels and can be used with CMOS or
TTL logic (see Table 4-6 and Table 4-7). Specific characteristics given in
Table 4-6 and Table 4-7 apply over an operating temperature range of –40° to
+85°C and a supply voltage range of 4.75 to 5.25 volts, unless otherwise noted.
