Product specification

74ALVC162836A

AC WAVEFORMS FOR VCC = 3.0 V TO 3.6 V AND

VCC = 2.7 V RANGE

VM = 1.5 V

VX = VOL + 0.3 V

VY = VOH – 0.3 V

VOL and VOH are the typical output voltage drop that occur with the

output load.

VI = 2.7 V

AC WAVEFORMS FOR VCC = 2.3 V TO 2.7 V AND

VCC < 2.3 V RANGE

VM = 0.5 VCC

VX = VOL + 0.15 V

VY = VOH – 0.15 V

VOL and VOH are the typical output voltage drop that occur with the

output load.
