DESCRIPTION (CONTINUED)
SN74ALVCHG162282
18-BIT TO 36-BIT REGISTERED BUS EXCHANGER
WITH 3-STATE OUTPUTS
SCES094D – FEBRUARY 1997 – REVISED OCTOBER 2004
The A-port N-channel output transistors are sized at 450
m, and the P-channel output transistors are sized at
700
m. All A-port outputs have equivalent 50- series resistors. The B-port N-channel output transistors are
sized at 225
m, and the P-channel output transistors are sized at 560 m. All B-port outputs have equivalent
20-
series resistors
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 port) loads, but are tested with the
standard 50-pF load.
The SN74ALVCHG162282 is characterized for operation from 0
°C to 70°C.

loaded in the first register when SEL is low and propagates to the
second register when SEL is high.
