| 描述与应用 | DUAL-BIT DUAL-SUPPLY BUS TRANSCEIVER WITH CONFIGURABLE VOLTAGE TRANSLATION AND 3-STATE OUTPUTS 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. The SN74LVC2T45 is designed so that the DIR input circuit is supplied by VCCA. This device is fully specified for partial-power-down applications using I off The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down. The VCC isolation feature ensures that if either VCC input is at GND, both ports are in the high-impedance state. NanoFree™ package technology is a major breakthrough in IC packaging concepts, using the die as the package. Available in the Texas Instruments NanoFree™ Package • Fully Configurable Dual-Rail Design Allows Each Port to Operate Over the Full 1.65-V to 5.5-V Power-Supply Range • VCC Isolation Feature – If Either VCC Input Is at GND, Both Ports Are in the High-Impedance State • DIR Input Circuit Referenced to VCCA • Low Power Consumption, 10-µA Max I CC • ±24-mA Output Drive at 3.3 V • off Supports Partial-Power-Down Mode Operation • Max Data Rates – 420 Mbps (3.3-V to 5-V Translation) – 210 Mbps (Translate to 3.3 V) – 140 Mbps (Translate to 2.5 V) – 75 Mbps (Translate to 1.8 V) • Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II • ESD Protection Exceeds JESD 22 – 4000-V Human-Body Model (A114-A) – 200-V Machine Model (A115-A) – 1000-V Charged-Device Model (C101) |
