3 Description
This 4-bit noninverting bus transceiver uses two
separate configurable power-supply rails. The A port
is designed to track VCCA. VCCA accepts any supply
voltage from 1.1 V to 3.6V. The B port is designed
to track VCCB. VCCB accepts any supply voltage
from 1.1 to 3.6V. The SN74AVC4T774 is optimized
to operate with VCCA/VCCB set at 1.4V to 3.6V.
It is operational with VCCA/VCCB as low as 1.2V.
This allows for universal low-voltage bi-directional
translation between any of the 1.2V, 1.5V, 1.8V, 2.5V,
and 3.3V voltage nodes.
The SN74AVC4T774 is designed for asynchronous
communication between data buses. The logic levels
of the direction-control (DIR) input and the outputenable( OE) input activate either the B-port outputs
or the A-port outputs or place both output ports in
the high-impedance mode. The device transmits data
from the A bus to the B bus when the B outputs are
activated, and from the B bus to the A bus when the
A outputs are activated. The input circuitry on both A
and B ports is always active and must have a logic
HIGH or LOW level applied to prevent excess ICC and
ICCZ.
The SN74AVC4T774 is designed so that the control
pins (DIR1, DIR2, DIR3, DIR4, and OE) are supplied
by VCCA. This device is fully specified for partialpower-
down applications using Ioff. 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, then both ports are in the highimpedance
state.
For a high-impedance state during power-up or
power-down, OE should be tied to VCCA through a
pullup resistor; the minimum value of the resistor
is determined by the current-sinking capability of
the driver. Since this device has CMOS inputs, it
is very important to not allow them to float. If the
inputs are not driven to either a high VCC state,
or a low-GND state, an undesirable larger than
expected ICC current may result. Since the input
voltage settlement is governed by many factors
(for example, capacitance, board-layout, package
inductance, surrounding conditions, and so forth),
ensuring that they these inputs are kept out of
erroneous switching states and tying them to either
a high or a low level minimizes the leakage-current.
