CAPACITANCE(1) Symbol Parameter Test Conditions TYP(2) Unit VCCA = VCCB = 3.3 V, VI = 0 V or CIN Control Pin Input Capacitance 3.5 pF VCCA/B VCCA = VCCB = 3.3 V, VI = 0 V or CI/O I/O Pin Input capacitance 5.0 pF VCCA/B VCCA = VCCB = 3.3 V, VI = 0 V or CPD Power Dissipation Capacitance 33 pF VCCA/B, f = 10 MHz (1) CPD is defined as the value of the IC's equivalent capacitance from which the operating current can be calculated from: ICC(operating) ≈ CPD × VCC × fIN × NSW where ICC = ICCA + ICCB and NSW = total number of outputs switching. (2) Typical values are at TA = +25 °C. Copyright © 2011, Texas Instruments Incorporated Submit Documentation Feedback 5 Product Folder Link(s): SN74AVC2T244 |
