description/ordering information

This 24-bit noninverting bus transceiver uses two separate configurable power-supply rails. The

SN74AVCH24T245 is optimized to operate with V

as low as 1.2 V. The A port is designed to track V

. V

CCA CCA

B port is designed to track V

. V

accepts any supply voltage from 1.2 V to 3.6 V. This allows for universal

CCB CCB

low-voltage bidirectional translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage nodes.

The SN74AVCH24T245 is designed for asynchronous communication between data buses. The device

transmits data 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 be used to disable the outputs so the buses are

effectively isolated.

The SN74AVCH24T245 is designed so that the control pins (1DIR, 2DIR, 3DIR, 4DIR, 5DIR, 6DIR, 1OE, 2OE,

3OE, 4OE, 5OE, and 6OE) are supplied by V

.

CCA

This device is fully specified for partial-power-down applications using I . The I circuitry disables the outputs,

The V

isolation feature ensures that if either V

input is at GND, then both ports are in the high-impedance

CC

Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors

with the bus-hold circuitry is not recommended.

To ensure the high-impedance state during power up or power down, OE should be tied to V

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES: 1. The input voltage and output negative-voltage ratings may be exceeded if the input and output current ratings are observed.

2. The output positive-voltage rating may be exceeded up to 4.6 V maximum if the output current rating is observed.

3. The package thermal impedance is calculated in accordance with JESD 51-7.

TBD: The Pb-Free/Green conversion plan has not been defined.

Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements

for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered

at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.

Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame

retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
