Octal-Bus Transceiver,
Three-State, Non-Inverting
Description
The ’AC245 and ’ACT245 are octal-bus transceivers that
utilize Advanced CMOS Logic technology. They are non-
inverting
three-state
bidirectional
transceiver-buffers
intended for two-way transmission from “A” bus to “B” bus or
“B” bus to “A”. The logic level present on the direction input
(DIR) determines the data direction. When the output enable
input (OE) is HIGH, the outputs are in the high-impedance
state.
Features
• Buffered Inputs
• Typical Propagation Delay
- 4ns at V

• SCR-Latchup-Resistant CMOS Process and Circuit
Design
• Speed of Bipolar FAST™/AS/S with Significantly
Reduced Power Consumption
• Balanced Propagation Delays
• AC Types Feature 1.5V to 5.5V Operation and
Balanced Noise Immunity at 30% of the Supply
