The following conditions apply unless otherwise specified: Commercial: TA = 0 °C to +70°C, VCC = 5.0V ± 5%; Military: TA = –55°C to +125°C, VCC = 5.0V ± 10% Symbol Parameter Test Conditions (1) Min. Typ. (2) Max. Unit ICCQ Quiescent Power Supply Current VIN = VCC or GND — — 5 mA CMOS Input Levels VCC = Max. All Inputs Outputs Disabled ICCQT Quiescent Power Supply Current VIH = 3.4V, VIL = 0V — — 1 mA/ TTL Input Levels VCC = Max. All Inputs input Outputs Disabled ICCD1 Dynamic Power Supply Current fCP = 10MHz, 50% Duty Cycle COM'L. — — 100 mA f = 10MHz VIH = VCC, VIL = GND Read Mode, Outputs Disabled MIL. — — 115 ICCD2 Dynamic Power Supply Current fCP = 20MHz, 50% Duty Cycle COM'L. — — 200 mA f = 20MHz VIH = VCC, VIL = GND Read Mode, Outputs Disabled MIL. — — 230 NOTES: 2552 tbl 22 1. For conditions shown as Min. or Max., use appropriate value specified above for the applicable device type. 2. Typical values are at VCC = 5.0V, +25 °C ambient temperature, and maximum loading. 3. Total supply current is the sum of the Quiescent current and the dynamic current and is calculated as follows: ICC = ICCQ + ICCQT (NT x DT) + ICCD (fOP) where: NT = Total # of quiescent TTL inputs DT = AC Duty cycle – % of time high (TTL) fOP = Operating frequency |
