资 源 简 介
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 SN74LVCH16T245 is designed so that the control pins (1DIR, 2DIR, 1OE, and 2OE) are supplied by VCCA.
The SN74LVCH16T245 is designed for asynchronous communicaTIon between two data buses. The logic levels of 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.
