Product data sheet Rev. 03 — 7 May 2008 6 of 16 NXP Semiconductors 74LVT241 3.3 V octal buffer/line driver; 3-state [1] All typical values are measured at Tamb =25 °C. [2] Unused pins at VCC or GND. [3] This is the bus hold overdrive current required to force the input to the opposite logic state. [4] This parameter is valid for any VCC between 0 V and 1.2 V with a transition time of up to 10 ms. From VCC =1.2 VtoVCC = 3.3 V ± 0.3 V a transition time of 100 ms is permitted. This parameter is valid for Tamb = +25 °C only. [5] ICC with the outputs disabled is measured with outputs pulled to VCC or GND. [6] This is the increase in supply current for each input at the specified voltage level other than VCC or GND. 10. Dynamic characteristics ICC supply current VCC = 3.6 V; VI =VCC or GND; IO =0A outputs HIGH - 0.12 0.19 mA outputs LOW - 3 12 mA outputs disabled [5] - 0.12 0.19 mA ∆ICC additional supply current per input pin; VCC = 3.0 V to 3.6 V; one input = VCC − 0.6 V other inputs at VCC or GND [6] - 0.1 0.25 mA CI input capacitance 1OE and 2OE inputs; outputs disabled; VI = 0 V or 3.0 V -4 - pF CI/O input/output capacitance at input/output data pins, outputs disabled; VI/O = 0 V or 3.0 V -8 - pF Table 6.
