7 / 10 page Philips Semiconductors Product specification 74LVC16374A/ 74LVCH16374A 16-bit edge triggered D-type flip-flop with 5 Volt tolerant inputs/outputs (3-State) 1998 Mar 17 7 AC WAVEFORMS VM = 1.5V at VCC w 2.7V; VM = 0.5 VCC at VCC t 2.7V. VOL and VOH are the typical output voltage drop that occur with the output load. VX = VOL + 0.3V at VCC w 2.7V; VX = VOL + 0.1 VCC at VCC t 2.7V VY = VOH –0.3V at VCC w 2.7V; VY = VOH – 0.1 VCC at VCC t 2.7V VM VM 1/fMAX tw tPHL tPLH CP INPUT Qn OUTPUT SW00078 GND VOH VOL VI Waveform 1.
