MAX14548AE - 16-Channel LLTs

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.

Key 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 VCC is less than VL. The MAX14548AE output driver is designed to operate at full speed (100Mbps) with VL > 1.4V, which reduces the dynamic supply current vs. the MAX14548E. The state of I/O VCC_and I/O VL_are in high-impedance state during shutdown. The devices operate with VCC voltages from +1.7V to +3.6V and VL voltages from +1.1V to +3.

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.
