operation.
16-bit
(dual-octal)
noninverting
bus
The SN74LVCR162245 is designed for asynchronous communication between data buses. The control
function implementation minimizes external timing requirements.
This device can be used as two 8-bit transceivers or one 16-bit transceiver. It allows data transmission from the
A bus to the B bus or from the B bus to the A bus, depending upon the logic level at the direction-control (DIR)
input. The output-enable (OE) input can be used to disable the device so that the buses are effectively isolated.
All outputs, which are designed to sink up to 12 mA, include 26-
resistors to reduce overshoot and undershoot.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
To ensure the high-impedance state during power up or power down, OE should be tied to V
CC
through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The SN74LVCR162245 is characterized for operation from –40
°
C to 85
°
C.
