Description

This 16-bit (dual-octal) noninverting bus transceiver SN74LVCHR16245A is designed for 1.65-V to 3.6-V V_CC operation.

The SN74LVCHR16245A is designed for asynchronous communication between data buses. The control-function implementation minimizes external-timing requirements.

This device SN74LVCHR16245A 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 on the logic level at the direction-control (DIR) input. The output-enable (OE) input can disable the device so that the buses are effectively isolated.

SN74LVCHR16245A All outputs, which are designed to sink up to 12 mA, include equivalent 26-series resistors to reduce overshoot and undershoot.

To ensure the high-impedance state during power up or power down, SN74LVCHR16245A OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

SN74LVCHR16245A Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators in a mixed 3.3-V/5-V system environment.

Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level. The SN74LVCHR16245A is characterized for operation from 40 to 85.
