Product data sheet Rev. 05 — 21 March 2006 7 of 16 Philips 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. 11.
