16-BIT 2.5-V TO 3.3-V/3.3-V TO 5-V LEVEL-SHIFTING TRANSCEIVER

WITH 3-STATE OUTPUTS

SCAS416P – MARCH 1994 – REVISED NOVEMBER 2005

• Member of the Texas Instruments Widebus™

Family

• Max t

of 5.8 ns at 3.3 V

• ± 24-mA Output Drive at 3.3 V

• Control Inputs V

Levels Are Referenced

to V

CCA

Voltage

• Latch-Up Performance Exceeds 250 mA Per

JESD 17

This 16-bit (dual-octal) noninverting bus transceiver

contains two separate supply rails. B port has V

CCB

which is set to operate at 3.3 V and 5 V. A port has

CCA

, which is set to operate at 2.5 V and 3.3 V. This

allows for translation from a 2.5-V to a 3.3-V

environment, and vice versa, or from a 3.3-V to a 5-V

environment, and vice versa.

The SN74ALVC164245 is designed for asynchronous

communication between data buses. The control

circuitry (1DIR, 2DIR, 1 OE, and 2 OE) is powered by

CCA

To ensure the high-impedance state during power up

or power down, the output-enable ( OE) input should

be tied to V

through a pullup resistor; the minimum

value of the resistor is determined by the

current-sinking capability of the driver.
