6-Channel High-Speed Logic-Level Translators
–MAX1035E
General Description
Features
The MAX13030E–MAX13035E 6-channel, bidirectional
level translators provide the level shifting necessary for
100Mbps data transfer in multivoltage systems. The
MAX13030E–MAX13035E are ideally suited for memo-
ry-card level translation, as well as generic level trans-
lation in systems with six channels. Externally applied

Typical Operating Circuits
The MAX13030E–MAX13034E feature an enable (EN)
input that places the device into a low-power shutdown
mode when driven low. The MAX13030E–MAX13035E
features an automatic shutdown mode that disables the
