Product specification
74ALVC162835A
AC WAVEFORMS FOR VCC = 3.0V TO 3.6V AND
VCC = 2.7V RANGE
VM = 1.5 V
VX = VOL + 0.3V
VY = VOH – 0.3V
VOL and VOH are the typical output voltage drop that occur with the
output load.
VI = 2.7V
AC WAVEFORMS FOR VCC = 2.3V TO 2.7V AND
VCC < 2.3V RANGE
VM = 0.5 VCC
VX = VOL + 0.15V
VY = VOH – 0.15V
VOL and VOH are the typical output voltage drop that occur with the
output load.
