Storage Temperature ........................Com’l -55 °C to +125°C Ambient Temperature with Power Applied....................................Com’l -55 °C to +125°C DC Input Voltage ........................................... –0.5V to +7.0V DC Output Voltage......................................... –0.5V to +7.0V DC Output Current (Maximum Sink Current/Pin) ........................–60 to +120 mA Power Dissipation .......................................................... 1.0W Static Discharge Voltage............................................>2001V (per MIL-STD-883, Method 3015) Notes: 1. On CY74FCT162H245T these pins have bus hold. 2. H = HIGH Voltage Level. L = LOW Voltage Level. X = Don’t Care. Z = High Impedance. 3. Operation beyond the limits set forth may impair the useful life of the device. Unless otherwise noted, these limits are over the operating free-air temperature range. 4. Unused inputs must always be connected to an appropriate logic voltage level, preferably either VCC or ground.
