Rainbow Electronics MAX13045E User Manual

General Description

The MAX13042E–MAX13045E 4-channel, bidirectional level translators provide the level shifting necessary for 100Mbps data transfer in multivoltage systems. The MAX13042E–MAX13045E are ideally suited for level translation in systems with four channels. Externally applied voltages, VCCand VL, set the logic levels on either side of the device. Logic signals present on the VLside of the device appear as a high-voltage logic signal on the VCCside of the device and vice-versa.

The MAX13042E–MAX13045E operate at full speed with external drivers that source as little as 4mA output current or larger. Each input/output (I/O) channel is pulled up to V

or VLby an internal 30µA current source, allowing the MAX13042E–MAX13045E to be driven by either push-pull or open-drain drivers.

The MAX13042E–MAX13045E feature an enable (EN) input that places the devices into a low-power shutdown mode when driven low. The MAX13042E–MAX13045E feature an automatic shutdown mode that disables the part when VCCis less than VL. The state of I/O V

CC_

and I/O VL_during shutdown is chosen by selecting the appropriate part version. (See the Ordering Information/ Selector Guide).

The MAX13042E–MAX13045E operate with VCCvoltages from +2.2V to +3.6V and VLvoltages from +1.62V to +3.2V, making them ideal for data transfer between low-voltage ASIC/PLDs and higher voltage systems. The MAX13042E–MAX13045E are available in 12-bump UCSP™ (1.54mm x 2.12mm) and 14-pin TDFN (3mm x 3mm) packages, and operate over the extended -40°C to +85°C temperature range.

Note 1: All units are 100% production tested at T

= +25°C. Limits over the operating temperature range are guaranteed by

correlation and design and not production tested.

Note 2: V

must be less than or equal to VCCduring normal operation. However, VLcan be greater than VCCduring startup and

shutdown conditions.

Note 3: When V

is below VLby more than the VL- VCCshutdown threshold, the device turns off its pullup generators and the I/Os

enter their respective shutdown states.

Note 4: Guaranteed by design. Note 5: Input thresholds are referenced to the boost circuit.
