Логическая ИС SN74LVTH162244DL

Буфер / драйвер линии , неинвертирующий, 3 состояния, 2.7В до 3.6В, SSOP-48

The SN74LVTH162244DL is a 16-bit Buffer/Line Driver designed for low-voltage (3.3V) VCC operation, but with the capability to provide a TTL interface to a 5V system environment. This device can be used as four 4-bit buffers, two 8-bit buffers or one 16-bit buffer. This device provides true outputs and symmetrical active-low output-enable (OE) inputs. The outputs, which are designed to source or sink up to 12mA, include equivalent 22R series resistors to reduce overshoot and undershoot. Active bus-hold circuitry holds unused or un-driven inputs at a valid logic state. Use of pull-up/pull-down resistors with the bus-hold circuitry is not recommended. When VCC is between 0 and 1.5V, the device is in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 1.5V, OE should be tied to VCC through a pull-up resistor and the minimum value of the resistor is determined by the current-sinking capability of the driver.

• Support mixed-mode signal operation
• IOFF and power-up 3-state support hot insertion
• Bus hold on data inputs eliminates the need for external pull-up/pull-down resistors
• Distributed VCC and GND pins minimize high-speed switching noise
• Flow-through architecture optimizes PCB layout
• Latch-up performance exceeds 500mA per JESD 17
• Support unregulated battery operation down to 2.7V
• <0.8V at VCC = 3.3V, TA = 25°C VOLP (output ground bounce)
• Green product and no Sb/Br
