TTL INPUT DC CHARACTERISTICS VCC = 4.75 V to 5.25 V; TA = −40°C to 85°C Symbol Characteristic Condition Min Typ Max Unit IIH Input HIGH Current VIN = 2.7 V 20 mA IIHH Input HIGH Current VIN = 7.0 V 100 mA IIL Input LOW Current VIN = 0.5 V −0.6 mA VIK Input Clamp Diode Voltage IIN = −18 mA −1.2 V VIH Input HIGH Voltage 2.0 V VIL Input LOW Voltage 0.8 V NOTE: Device will meet the specifications after thermal equilibrium has been established when mounted in a test socket or printed circuit board with maintained transverse airflow greater than 500 lfpm. Electrical parameters are guaranteed only over the declared operating temperature range. Functional operation of the device exceeding these conditions is not implied. Device specification limit values are applied individually under normal operating conditions and not valid simultaneously. Table 8.
