SNx4ACT244 Octal Buffers and Drivers With 3-State Outputs

1 Features

• 4.5V to 5.5V VCC operation

• Inputs accept voltages to 5.5V

• Maximum tpd of 9.5ns at 5V

• Inputs are TTL-compatible

• On products compliant to MIL-PRF-38535,

all parameters are tested unless otherwise noted.

On all other products, production processing does

not necessarily include testing of all parameters.

2 Applications

• LED displays

• Servers and telecommunication

• Switching networks

3 Description

These SNx4ACT244 octal buffers and drivers are

designed specifically to improve the performance and

density of 3-state memory address drivers, clock

drivers, and bus-oriented receivers and transmitters.

The SNx4ACT244 devices are organized as two 4-

bit buffers and drivers with separate output-enable

(OE) inputs. When OE is low, the device passes non-

inverted data from the A inputs to the Y outputs.

When OE is high, the outputs are in the high-

impedance state.
