Professional supply SN74AVC4T245RGYR 4-BIT DUAL-SUPPLY BUS TRANSCEIVER WITH CONFIGURABLE VOLTAGE TRANSLATION AND 3-STATE OUTPUTS
Voltage Level Translator 4-CH Bidirectional 16-Pin VQFN EP T/R
Product Descriptions
This 4-bit noninverting bus transceiver uses two separate configurable power-supply rails. The A port isdesigned to track VCCA. VCCA accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to trackVCCB. VCCB accepts any supply voltage from 1.2 V to 3.6 V.
The SN74AVC4T245 is optimized to operate withVCCA/VCCB set at 1.4 V to 3.6 V. It is operational with VCCA/VCCB as low as 1.2 V. This allows for universallow-voltage bidirectional translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage nodes.
The SN74AVC4T245 is designed for asynchronous communication between data buses. The device transmitsdata from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at thedirection-control (DIR) input. The output-enable (OE) input can be used to disable the outputs so the buses areeffectively isolated.
The SN74AVC4T245 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.
