This 16-bit noninverting bus transceiver uses two
separate configurable power-supply rails. The A port
is designed to track VCCA. VCCA accepts any supply
voltage from 1.65 V to 5.5 V. The B port is designed
to track VCCB. VCCB accepts any supply voltage from
1.65 V to 5.5 V. This allows for universal low-voltage
bidirectional translation between any of the 1.8-V,
2.5-V, 3.3-V, and 5-V voltage nodes.
the direction-control (DIR) input and the output-enable (OE) input activate either the B-port outputs or the A-port
outputs or place both output ports into the high-impedance mode. The device transmits data from the A bus to
the B bus when the B-port outputs are activated, and from the B bus to the A bus when the A-port outputs are
activated. The input circuitry on both A and B ports is always active and must have a logic HIGH or LOW level
applied to prevent excess ICC and ICCZ.
The SN74LVC16T245 is designed so that the control pins (1DIR, 2DIR, 1OE, and 2OE) are supplied by VCCA.
This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.
