· Direct interface with TTL levels· All data inputs have bus hold (74ALVCH16245 only)· Output drive capability 50 transmission lines @ 85°C· Current drive 3.0 V

DESCRIPTION

The a 16-bit transceiver featuring non-inverting 3-State bus compatible outputs in both send and receive directions. The 74ALVC16245(74ALVCH16245) features two output enable (nOE) inputs for easy cascading and two send/receive (nDIR) inputs for direction control. nOE controls the outputs so that the buses are effectively isolated. This device can be used as two 8-bit transceivers or one 16-bit transceiver. The 74ALVCH16245 has active bus hold circuitry which is provided to hold unused or floating data inputs at a valid logic level. This feature eliminates the need for external pull-up or pull-down resistors. The 74ALVC16245 has 5V tolerant inputs.

NOTE: 1. CPD is used to determine the dynamic power dissipation (PD in µW): PD = CPD + S (CL VCC2 × fo) where: fi = input frequency in MHz; CL = output load capacitance in pF; fo = output frequency in MHz; VCC = supply voltage V; S (CL VCC2 × fo) = sum of the outputs.
