www.DataSheet4U.com 19-5248; Rev 0; 4/10 TION KIT EVALUA BLE IL AVA A 100Mbps, 16-Channel LLTs MAX14548E/MAX14548AE General Description The MAX14548E/MAX14548AE 16-channel, bidirectional level translators (LLTs) provide the level shifting necessary for 100Mbps data transfer in multivoltage systems. 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 high-voltage logic signal on the VCC side of the device and vice versa. The devices feature a programming frequency input (PF) that adjusts the one-shot accelerator on-time to guarantee a bit rate of 100Mbps with a load capacitance < 15pF and VL > 1.1V (MAX14548E) or VL > 1.4V (MAX14548AE) when driven low. The MAX14548E can drive capacitive loads up to 50/R 1.1pF with a guaranteed bit rate of 40Mbps when VL > 1.1/R 1.1V and PF is driven high. The MAX14548AE can drive capacitive loads up to 50pF with a guaranteed bit rate of 40Mbps when VL > 1.1V and PF is driven high. The device operate at full speed with external drivers that source as low as 4mA output current. Each I/O channel is pulled up to VCC or VL by an internal 35FA current source, allowing both devices to be driven by either push-pull or open-drain drivers. The devices feature multiple power-saving features including an enable input (EN) that places the device into a low-power shutdown mode when driven low and an automatic shutdown mode that disables the part when VC...
