6-Channel High-Speed Logic-Level Translators
General Description
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 memory-card level translation, as well as generic level translation in systems with six channels. Externally applied voltages, VCC and VL, set the logic levels on either side of the device. Logic signals present on the VL side of the device appear as a higher voltage logic signal on the V CC side of the device and vice versa. The MAX13035E features a CLK_RET output that returns the same clock signal applied to the CLK_VL input. The MAX13030E–MAX13035E operate at full speed with external drivers that source as little as 4mA output current. Each I/O channel is pulled up to VCC or VL by an internal 30µA current source, allowing the MAX13030E–MAX13035E to be driven by either pushpull or open-drain drivers. 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 www.DataSheet4U.com part when V CC is less than VL. The state of I/O VCC_ and I/O VL_ during shutdown is chosen by selecting the appropriate part version (see Ordering Information/ Selector Guide). The MAX13030E–MAX13035E accept V CC voltages from +2.2V to +3.6V and VL voltages from +1.62V to +3.2V, making them ideal for data transfer between low-voltage ASIC/PLDs and higher voltage systems. The MAX13030E–MAX13035E are available in 16-bump UCSP (2mm x 2mm) and 16-pin TQFN (4mm x 4mm) packages, and operate over the extended -40°C to +85°C temperature range. o 100Mbps Guaranteed Data Rate o Six Bidirectional Channels o Clock Return Output (MAX13035E) o Enable Input (MAX13030E–MAX13034E) o ±15kV ESD Protection on I/O VCC Lines o +1.62V ≤ VL ≤ +3.2V and +2.2V ≤ VCC ≤ +3.6V Supply Voltage Range o Lead-Free, 16-Bump UCSP (2mm x 2mm) and 16-pin TQFN (4mm x 4mm) Packages
