Преобразователи логического уровня SN74LVC16T245DGGR

Приемопередатчик , неинвертирующий, 1.65В до 5.5В, TSSOP-48

The SN74LVC16T245DGGR is a 16-bit dual-supply Bus Transceiver with configurable level-shifting or voltage translation. The SN74LVC16T245 device 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 always is active and must have a logic HIGH or LOW level applied to prevent excess ICC and ICCZ.

• Control inputs VIH/VIL levels are referenced to VCCA voltage
• Overvoltage-tolerant inputs and outputs allow mixed voltage-mode data communications
• Fully configurable dual-rail design
• IOFF supports partial-power-down mode operation
• Latch-up performance exceeds 100mA per JESD 78
• ESD protection exceeds JESD 22

Области применения

Промышленное, Связь и Сеть This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
