This dual-bit noninverting bus transceiver uses two
separate configurable power-supply rails. TheA port designedto track VCCA. VCCA accepts any supply
voltage from 1.65Vto 5.5V. TheB portis designed track VCCB. VCCB accepts any supply voltage from
1.65Vto 5.5V. This allows for universal low-voltage
bidirectional translation between any of the 1.8-V,
2.5-V, 3.3-V, and 5-V voltage nodes.
The SN74LVC2T45is designed for asynchronous
communication between two data buses. The logic
levels of the direction-control (DIR) input activate
either the B-port outputsor the A-port outputs. The
device transmits data from theA busto theB bus
when the B-port outputs are activated, and from theB
bus to theA bus when the A-port outputs are
activated. The input circuitry on bothA andB ports
alwaysis active and must havea logic HIGHor LOW
level appliedto prevent excess ICC and ICCZ.
The SN74LVC2T45is designedso that the DIR input
circuit is supplied by VCCA. This device is fully
specified for partial-power-down applications using
Ioff. The Ioff circuitry disables the outputs, preventing
damaging current backflow through the device whenis powered down.
The VCC isolation feature ensures thatif either VCC
inputisat GND, both ports arein the high-impedance
state. NanoFree™ package technologyisa major
breakthroughinIC packaging concepts, using the die the package.
