DESCRIPTION (CONTINUED)

SN74ALVCHG162280

16-BIT TO 32-BIT REGISTERED BUS EXCHANGER

WITH BYTE MASKS AND 3-STATE OUTPUTS

SCES093D – FEBRUARY 1997 – REVISED OCTOBER 2004

The A-port N-channel output transistors are sized at 450

µm, and the P-channel output transistors are sized at

700

µm. All A-port outputs have equivalent 50-Ω series resistors. The B-port N-channel output transistors are

sized at 225

µm, and the P-channel output transistors are sized at 560 µm. All B-port outputs have equivalent

20-

Ω series resistors.

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

Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.

The switching characteristics are based on 25-pF (A port) and 80-pF (B and D ports) loads, but are tested with

the standard 50-pF load.

The SN74ALVCHG162280 is characterized for operation from 0

°C to 70°C.
