Product data sheet Rev. 08 — 22 March 2010 8 of 18 NXP Semiconductors 74LVT16244B; 74LVTH16244B 3.3 V 16-bit buffer/driver; 3-state [1] Typical values are measured at VCC = 3.3 V and 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 V to VCC = 3.3 V ± 0.3 V a transition time of 100 μs is permitted. This parameter is valid for T amb = 25 °C only. [5] ICC 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 [1] Typical values are measured at VCC = 3.3 V and Tamb = 25 °C. ICC supply current VCC = 3.6 V; VI = GND or VCC; IO =0A output HIGH - 0.07 0.12 mA output LOW - 4.0 6.0 mA outputs disabled [5] - 0.07 0.12 mA ΔI CC additional supply current per input pin; VCC = 3.0 V to 3.6 V; one input at VCC − 0.6 V other inputs at VCC or GND [6] -0.1 0.2 mA CI input capacitance VI = 0V or 3.0V - 3 - pF CO output capacitance outputs disabled; VO = 0 V or 3.0 V - 9 - pF Table 6.
