Octal Bidirectional Transceiver with 3-STATE
Inputs/Outputs
General Description
The AC/ACT245 contains eight non-inverting bidirectional
buffers with 3-STATE outputs and is intended for bus-ori-
ented applications. Current sinking capability is 24 mA at
both the A and B ports. The Transmit/Receive (T/R) input
determines the direction of data flow through the bidirec-
tional transceiver. Transmit (active-HIGH) enables data
from A ports to B ports; Receive (active-LOW) enables
data from B ports to A ports. The Output Enable input,
when HIGH, disables both A and B ports by placing them in
a HIGH Z condition.
Ordering Code:
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
Pb-Free package per JEDEC J-STD-020B.
Note 1: “_NL” indicates Pb-Free package (per JEDEC J-STD-020B). Device available in Tape and Reel only.
