SN74LVC2T45DCUR, 2-разрядный двухканальный приемопередатчик с настраиваемым сдвигом уровня напряжения и 3 состояниями на выходе

Описание SN74LVC2T45DCUR The SN74LVC2T45DCUR is a 2-bit non-inverting 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 to 5.5V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65 to 5.5V. This allows for universal low-voltage bidirectional translation between any of the 1.8, 2.5, 3.3 and 5 voltage nodes. The SN74LVC2T45 is designed for asynchronous communication between two data buses. The logic levels of the direction-control (DIR) input activate either the B-port outputs or the A-port outputs. 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. • DIR Input circuit referenced to VCCA • Low power consumption • Ioff Supports partial-power-down mode operation • Latch-up performance exceeds 100mA per JESD, 78 class II • ±24mA Output drive at 3.3V ТипТранслятор Уровня НапряженияТип каналадвунаправленныйКол-во схем1Кол-во каналов в схеме2Напряжение - VCC(A), В1.65…5.5Напряжение - VCC(B), В1.65…5.5Тип выхода3-state, non-invertedСкорость передачи данных420 mbpsРабочая температура, °C-40…+85Корпусvssop-8Вес, г0.08
