SN74LVC8T245QPWRQ1

Приемопередатчик, 3 состояния, неинвертирующий, 1.65В до 5.5В, TSSOP-24.

The SN74LVC8T245QPWRQ1 is a 8-bit dual-supply Bus Transceiver with voltage translation and 3-state outputs. The non-inverting bus transceiver uses two separate configurable power-supply rails. It is optimized to operate with VCCA and VCCB set at 1.65 to 5.5V. The A port is designed to track VCCA. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65 to 5.5V. It 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. 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.
