4 / 7 page  8.10 4 IDT74FCT163952/A/C 3.3V CMOS 16-BIT REGISTERED TRANSCEIVER COMMERCIAL TEMPERATURE RANGE NOTES: 1. For conditions shown as max. or min., use appropriate value specified under Electrical Characteristics for the applicable device type. 2. Typical values are at VCC = 3.3V, +25 °C ambient. 3. Per TTL driven input; all other inputs at VCC or GND. 4. This parameter is not directly testable, but is derived for use in Total Power Supply Calculations. 5. Values for these conditions are examples of the ICC formula. These limits are guaranteed but not tested. 6. IC = IQUIESCENT + IINPUTS + IDYNAMIC IC = ICC + ∆ICC DHNT + ICCD (fCPNCP/2 + fiNi) ICC = Quiescent Current (ICCL, ICCH and ICCZ) ∆ICC = Power Supply Current for a TTL High Input DH = Duty Cycle for TTL Inputs High NT = Number of TTL Inputs at DH ICCD = Dynamic Current Caused by an Input Transition Pair (HLH or LHL) fCP = Clock Frequency for Register Devices (Zero for Non-Register Devices) NCP = Number of Clock Inputs at fCP fi = Input Frequency Ni = Number of Inputs at fi POWER SUPPLY CHARACTERISTICS Symbol Parameter Test Conditions (1) Min.
