Product data sheet Rev. 06 — 6 March 2006 7 of 16 Philips Semiconductors 74LVT125; 74LVTH125 3.3 V quad buffer; 3-state [1] Typical values are measured at VCC = 3.3 V and 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 = 3.0 V to 3.6 V a transition time of 100 µs is permitted. This parameter is valid for Tamb =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. Dynamic characteristics [1] Typical values are at VCC = 3.3 V and Tamb =25 °C. ∆I CC additional quiescent supply current per input pin; VCC = 3 V to 3.6 V; one input at VCC − 0.6 V and other inputs at VCC or GND [6] - 0.1 0.2 mA Ci input capacitance VI = 0 V or 3.0 V - 4 - pF Co output capacitance outputs disabled; VO = 0 V or 3.0 V -8 -pF Table 7. Static characteristics …continued At recommended operating conditions; voltages are referenced to GND (ground = 0 V). Symbol Parameter Conditions Min Typ Max Unit Table 8. Dynamic characteristics Voltages are referenced to GND (ground = 0 V); for test circuit see Figure 8.
